‘Every building sits on a thermal asset’: how networked geothermal power could change cities
2024-08-09, The Guardian (One of the UK's Leading Newspapers)
Posted: 2024-10-01 13:49:22

There is a massive battery right under your feet. Unlike a flammable lithium ion battery, though, this one is perfectly stable, free to use, and ripe for sustainable exploitation: the Earth itself. While temperatures above ground fluctuate throughout the year, the ground stays a stable temperature, meaning that it is humming with geothermal energy. “Every building sits on a thermal asset,” said Cameron Best, director of business development at Brightcore Energy in New York, which deploys geothermal systems. “I really don’t think there’s any more efficient or better way to heat and cool our homes.” A couple of months ago Eversource Energy commissioned the US’s first networked geothermal neighbourhood operated by a utility, in Framingham, Massachusetts. Pipes run down boreholes 600-700ft (about 180-215 metres) deep, where the temperature of the rock is consistently 55F (13C). A mixture of water and propylene glycol ... pumps through the piping, absorbing that geothermal energy. Heat pumps use the liquid to either heat or cool a space. If deployed across the country, these geothermal systems could go a long way in helping decarbonise buildings, which are responsible for about a third of total greenhouse gas emissions in the US. Once a system is in place, buildings can draw heat from water pumped from below their foundations, instead of burning natural gas. The networks ... can be set up almost anywhere.

How a gas company and environmentalists united on a first-of-its-kind geothermal project
2024-08-29, Christian Science Monitor

In December 2016, William Akley sat down in his sprawling headquarters for the biggest gas utility in Massachusetts, Eversource. Across the table were three women from a group that had become increasingly troublesome to his company. The group was Mothers Out Front, and it had been doing things like dressing up in orange costumes depicting gas flames and putting big signs where the company’s natural gas lines leaked into the air. As the meeting started, Zeyneb Magavi and each of the other mothers calmly explained their passion to Mr. Akley: “I have three kids,” Ms. Magavi said. “I’m worried about climate change. And I’m worried about their future.” It was the start of an unlikely partnership that eventually became an audacious idea: to use heat from underground – instead of natural gas – to both cool and heat homes and buildings. The test of that idea is now blinking on in Framingham, Massachusetts. Eversource workers have buried a mile-long loop of plastic pipe underground ... to collect geothermal energy. They are now connecting the loop to heat and cool 36 buildings – homes, a fire station, and businesses. It is the first U.S. trial of this innovative technology being provided to an entire neighborhood by a major utility. It’s the kind of scaled-up model that could bring a wholesale change to the nation’s infrastructure, replacing natural gas just as natural gas supplanted coal and oil in much of the United States.

Robot controlled by a king oyster mushroom blends living organisms and machines

https://www.cnn.com/2024/09/04/science/fungus-robot-mushroom-biohybrid/index....

A wheeled bot rolls across the floor. A soft-bodied robotic star bends its five legs, moving with an awkward shuffle. Powered by conventional electricity via plug or battery, these simple robotic creations would be unremarkable, but what sets these two robots apart is that they are controlled by a living entity: a king oyster mushroom. By growing the mushroom’s mycelium, or rootlike threads, into the robot’s hardware, a team led by Cornell University researchers has engineered two types of robots that sense and respond to the environment by harnessing electrical signals made by the fungus and its sensitivity to light. The robots are the latest accomplishment of scientists in a field known as biohybrid robotics who seek to combine biological, living materials such as plant and animal cells or insects with synthetic components to make partly living and partly engineered entities. [Lead author Anand] Mishra engineered an electrical interface that accurately reads the mycelia’s raw electrical activity, then processes and converts it into digital information that can activate the robot’s actuators or moving parts. The robots were able to walk and roll as a response to the electrical spikes generated by the mycelia. [Professor of unconventional computing at the University of the West of England Andrew Adamatzky's] lab has produced more than 30 sensing and computing devices using live fungi, including growing a self-healing skin for robots that can react to light and touch. “When an adequate drivetrain (transmission system) is provided, the robot can, for example, monitor the health of ecological systems. The fungal controller would react to changes, such as air pollution, and guide the robot accordingly,” Adamatzky said.

How Nature Inspires Technology: The Field of Biomimicry

Posted: 2024-08-12 22:42:53
https://www.miragenews.com/how-nature-inspires-technology-the-field-of-1023128/

Biomimicry is grounded in the concept that nature, with its 3.8 billion years of evolution, has already solved many of the problems we grapple with today. Animals, plants, and microbes are the consummate engineers. Rather than designing new technology from scratch, scientists and engineers often look to nature for inspiration. In its approach, biomimicry involves three essential aspects: Emulating natural forms, mimicking natural processes, and imitating ecosystems. Nature operates under specific principles: it runs on sunlight, uses only the energy it needs, fits form to function, recycles everything, rewards cooperation, banks on diversity, demands local expertise, curbs excesses from within, and taps the power of limits. By aligning our technologies and practices with these principles, we can create not only innovative but also sustainable solutions to our challenges. Architects and engineers are designing buildings that mimic termite mounds, which maintain constant temperature despite external fluctuations. This biomimetic approach reduces energy consumption for heating and cooling. The self-cleaning properties of lotus leaves have inspired a whole range of products. The microscopic structure of a lotus leaf repels water and dirt particles. Today, we have self-cleaning paints and fabrics based on this principle. The bumps on the fins of humpback whales, called tubercles, increase their efficiency in water. Applying this concept to the design of wind turbines has led to blades that produce power more efficiently. Corals can heal themselves by producing an organic mineral in response to physical damage. Scientists have mimicked this process to create a type of concrete that can "heal" its own cracks.

Posted: 2024-07-02 11:12:38
https://reasonstobecheerful.world/philadelphia-reforestation-hub-carbon-smart...

Each year, US cities lose an estimated 36 million trees to development, disease and old age, many of which ultimately end up in landfills. Losing these urban trees — known to help cool their neighborhoods, lower carbon emissions and improve mental health, among other benefits — costs an estimated $96 million annually. In Philadelphia, a partnership is giving the City of Brotherly Love’s fallen trees new life. Philadelphia Parks & Rec joined forces with Cambium Carbon, a Washington, D.C.-based startup that repurposes waste wood, and PowerCorpsPHL, a local nonprofit that creates job opportunities for unemployed and under-employed 18- to 30-year-olds, to launch the Reforestation Hub. Rather than sending trees straight to the landfill or the city’s organic recycling center to simply become mulch or wood chips, the Reforestation Hub (which is co-located in the city’s organic recycling center) will salvage as many trees as it can. As many as possible will be turned into Cambium’s Carbon Smart Wood, which stores 5.23 pounds of carbon in each board foot. Fifteen percent of sales that come out of the hub will be donated to Tree Philly at the end of each year to support tree planting and maintenance across the city. While the hub formally launched only recently, in the year and a half that it’s taken to get the infrastructure in place, it has already diverted 542 logs to create 28,000 board feet of Carbon Smart Wood.

How the virtual world is inspiring gamers to become botanists

https://www.positive.news/society/virtual-world-inspiring-gamers-become-botan...

What if computer games could facilitate a tangible, meaningful connection with nature? Now they can thanks to a new botany project that empowers gamers to cultivate plants featured in their favourite video game. The idea was that of Hannah Young and Aleks Atanasovski, two gamers who wanted to fuse their love of nature with their passion for gaming. The result is Seed Saga, a botanical pilot that allows players of Guild Wars – a popular roleplaying game renowned for its spectacular flora – to apply for seed packs so they can grow plants that feature in the game. The pair pitched the idea to the developer behind Guild Wars, Arena Net, which was “really up for it”. So much so, that the firm provided renders from the game for the seed packets and gave the project a push on its social channels. Due to the limited availability of seeds ... gamers must submit an application explaining why they want them. The responses, says Young, have been heartening. Said one applicant: “[Guild Wars] saved my life during a period of deep depression. It would be an honour to grow [crimson sunflowers] in my yard to pay homage to the game and support the surrounding insects that could benefit from these flowers.” The first seed packs went out in April. The idea now is to partner with other players in the industry and scale the concept to cultivate a new generation of botanists. Doing so could boost mental health: research shows that interacting with plants counteracts stress brought on by computers.

Entrepreneurs in Jordan have created a sophisticated machine that pulls water from the desert air at a rate that could cure the country’s water woes. 1,000 units of their flagship device have already been pre-ordered by the Jordanian government, and the success of the invention has allowed the innovators to attract dozens of promising scientists who can hopefully expand on their success and bring water resources up to speed in the relatively-stable Near Eastern nation. Aquaporo [is] a relatively straightforward, air conditioning-sized machine that can harvest 35 liters of water every day in a desert climate of 20% humidity. Aquaporo CEO Kyle Cordova and engineering director Husam Almassad got their start at Jordan’s Royal Scientific Society. Their invention looked a bit like a chest freezer. Inside, rows of nanomaterials formed into tubes and other shapes act like a sieve that filters water out of the air. The physics behind it are much the same as those found in this Classical Indian architectural feature and takes advantage of air’s tendency to speed up as it moves through a narrow passageway; called the Venturi Effect. It leaves behind the heavier water vapor, which condenses, drops into a collection apparatus, and is fed then into a reservoir. Research on the efficacy of Aquaporo’s invention shows it can achieve levels of water purity greater than Nestle brand bottled water, and collects it from the air at double the rate of existing moisture capture technology.

Deep underground, robotic teamwork saves the day

When a Manhattan parking garage collapsed in April this year, rescuers were reluctant to stay in the damaged building, fearing further danger. So they used a combination of flying drones and a doglike walking robot to inspect the damage, look for survivors and make sure the site was safe for human rescuers to return. Soon, rescuers may be able to call on a much more sophisticated robotic search-and-rescue response. Researchers are developing teams of flying, walking and rolling robots that can cooperate to explore areas that no one robot could navigate on its own. And they are giving robots the ability to communicate with one another and make many of their own decisions independent of their human controller. Such teams of robots could be useful in other challenging environments like caves or mines where it can be difficult for rescuers to find and reach survivors. In cities, collapsed buildings and underground sites such as subways or utility tunnels often have hazardous areas where human rescuers can’t be sure of the dangers. As robots become better, teams of them may one day be able to go into a hazardous disaster site, locate survivors and report back to their human operators with a minimum of supervision. “More work ... needs to be done,” [roboticist Viktor] Orekhov says. “But at the same time, we’ve seen the ability of the teams advanced so rapidly that even now, with their current capabilities, they’re able to make a significant difference in real-life environments.”

https://reasonstobecheerful.world/future-affordable-housing-3d-printed-recycl...

When you imagine a 3D-printed home, you probably picture a boxy concrete structure. As 3D printing’s popularity has grown in the construction industry — thanks to its efficiency when it comes to time, energy and cost — carbon-intensive concrete has become the go-to building material. But a project in Maine has set its sights on something different: a neighborhood of 600-square-foot, 3D-printed, bio-based houses crafted from materials like wood fibers and bioresins. The aim: a complex of 100-percent recyclable buildings that will provide homes to those experiencing houselessness. In late 2022, an initiative between the University of Maine and local nonprofit Penquis unveiled its prototype — BioHome3D, the first 100-percent recyclable house. Now, the pioneering project is working toward completing its first livable housing complex. It will be fully bio-based, meaning all materials will be derived from living organisms such as plants and other renewable agricultural, marine and forestry materials. As the materials are all 100-percent recyclable, so become the buildings. The materials are also all renewable. And thanks to its natural composition, the home acts as a carbon sink, sequestering 46 tons of carbon dioxide per 600-square-foot unit. The materials for this project will mainly come from wood left over by local mills. “The wood fiber material that’s used in the mix is essentially waste wood here in Maine,” says Jason Bird, director of housing development for Penquis.

More than 300 electric cooperatives across the United States are building their own Internet with high-speed fiber networks. These locally-owned networks are poised to do what federal and state governments and the marketplace have not accomplished. First, they are protecting open Internet access from the Internet service providers (ISPs) that stand to pocket the profits from the rollbacks of net neutrality the Trump administration announced. Second, they are making affordable and fast Internet accessible to anyone. In Detroit, for example, 40 percent of the population has no access of any kind to the Internet. Detroit residents started a grassroots movement called the Equitable Internet Initiative, through which locals have begun to build their own high-speed Internet. The initiative started by enlisting digital stewards—locals who were interested in working for the nonprofit coalition. They aim to build shared tools, like a forum and a secured emergency communication network—and to educate their communities on digital literacy. Just 30 of the more than 300 tribal reservations in the United States have Internet access. Seventeen tribal reservation communities in San Diego County have secured wireless Internet access under the Tribal Digital Village initiative. Another local effort, Co-Mo Electric Cooperative ... has organized to crowdfund the necessary resources to establish its own network. The biggest dilemma for cities is the erosion of the capacity for communities to solve their own problems. As a result, local Internet service providers are bringing the power back to their people.

Social media platforms have become an integral part of our lives, but they also pose significant challenges for our society. From spreading misinformation and hate speech to undermining democracy and privacy, social media can have negative impacts on the public good. How can we harness the power of social media for positive purposes, such as civic engagement, social justice, and education? One possible solution is to create a new kind of social media platform that is designed to serve the public interest, not the profit motive. This platform would be owned and governed by its users, who would have a say in how it operates and what content it promotes. Such a platform may sound utopian, but it is not impossible. In fact, there are already some examples of social media platforms that are trying to achieve these goals, such as Mastodon, Diaspora, and Aether. These platforms are based on the principles of decentralization, federation, and peer-to-peer communication, which allow users to have more control and autonomy over their online interactions. Civic Works ... is an emerging social networking platform that provides a more democratic, inclusive, and responsible online space for everyone. It is built on the idea that social media can be a force for good when the objective is not subverted by advertisers, marketers, or shadowy political operatives. It is a platform that inspires people to become active citizens, through civic, political, economic, and/or educational actions.

'Ways of Being' Review: Whole Earth Network

The artist, writer and technologist James Bridle begins "Ways of Being" with an uncanny discovery: a line of stakes tagged with unfathomable letters and numbers in thick marker pen. The region of [Greece] is rich in oil, we learn, and the company that won the contract to extract it from the foothills of the Pindus mountains is using "cognitive technologies" to "augment ... strategic decision making." The grid of wooden stakes left by "unmarked vans, helicopters and work crews in hi-vis jackets" are the "tooth- and claw-marks of Artificial Intelligence, at the exact point where it meets the earth." "Ways of Being" sets off on a tour of the natural world, arguing that intelligence is something that "arises ... from thinking and working together," and that "everything is intelligent." We hear of elephants, chimpanzees and dolphins who resist and subvert experiments testing their sense of self. We find redwoods communicating through underground networks. In the most extraordinary result of all, in 2014 the Australian biologist Monica Gagliano showed that mimosa plants can remember a sudden fall for a month. Ever since the Industrial Revolution, science and technology have been used to analyze, conquer and control. But "Ways of Being" argues that they can equally be used to explore and augment connection and empathy. The author cites researchers studying migration patterns with military radar and astronomers turning telescopes designed for surveillance on Earth into instruments for investigating the dark energy of the cosmos.

Researchers Use Algae to Power a Computer for Months

https://www.smithsonianmag.com/smart-news/researchers-use-algae-to-power-comp...

Researchers have discovered how to use cyanobacteria—commonly called blue-green algae—to continuously power a microprocessor for a span of more than six months. The system, which uses inexpensive and largely recyclable materials, contains a type of non-toxic photosynthetic algae called Synechocystis, per a statement. The research was published in the journal Energy & Environmental Science. “We were impressed by how consistently the system worked over a long period of time—we thought it might stop after a few weeks but it just kept going,” says Paolo Bombelli, a researcher from the University of Cambridge’s Department of Biochemistry and lead author of the paper. The scientists created an enclosure out of aluminum and clear plastic and put the bacteria inside it. The device, which is about the size of a AA battery, was placed on a windowsill in Bombelli’s home during Covid-19 lockdown in 2021 and remained there from February to August. The bacteria powered an Arm Cortex M0+ processor—a microprocessor widely used in the network of appliances connected to the internet, also called the Internet of Things (IoT). The cyanobacteria produced energy even without light, perhaps because they process some of their food in the dark, which generates an electrical current. Several billion IoT devices already exist, and that number is expected to rise to one trillion by 2035. Powering all those devices would require 109,000 tons of lithium, which is three times more than what the world produced in 2017.

New Mobile Phone Service Shows We Can Have Both Privacy and Nice Things

Posted: 2023-04-10 13:03:04
https://wp.api.aclu.org/news/privacy-technology/new-mobile-phone-service-show...

The recent launch of a new mobile phone service introduced significant new privacy protections into the mobile phone system. This exciting new approach highlights the failure of the existing mobile phone infrastructure to protect privacy, and points the way forward for a wide variety of technologies. Today’s cellphones are generally a privacy disaster. Partly that’s the result of the two companies that control the operating system software on the vast majority of the world’s pocket computers. In order for your carrier to route calls and data to your phone, the network needs to constantly know which cell tower your phone is near. And when you make a call or use data, the provider can see where that traffic is going. Cell carriers track and store this accidental byproduct of the technology in order to record people’s location history and network activity for marketing purposes and, in certain circumstances, for sharing with law enforcement. The new phone service, called Pretty Good Phone Privacy (PGPP), uses encryption techniques to deliberately blind itself so that it can’t know that the user of a mobile device is you, or what data you are sending from that phone. You connect to the PGPP service for payment, and that’s all. With PGPP’s approach, the carrier simply does not have the data to turn over to anyone. It cannot be sold, leaked, or hacked, let alone offered to overreaching law enforcement agencies. Verizon, T-Mobile, AT&T, and their smaller competitors could be offering such a privacy-protecting service, but don’t want to.

‘Dead’ Electric Car Batteries Find a Second Life Powering Cities

https://reasonstobecheerful.world/electric-vehicle-batteries-reused-power-sta...

Last month, a small warehouse in the English city of Nottingham received the crucial final components for a project that leverages the power of used EV batteries to create a new kind of circular economy. Inside, city authorities have installed 40 two-way electric vehicle chargers that are connected to solar panels and a pioneering battery energy storage system, which will together power a number of on-site facilities and a fleet of 200 municipal vehicles. Each day Nottingham will send a combination of solar-generated energy — and whatever is left in the vehicles after the day’s use — from its storage devices into the national grid. What makes the project truly circular is the battery technology itself. Funded by the European Union’s Interreg North-West Europe Programme, the energy storage system, E-STOR, is made out of used EV batteries by the British company Connected Energy. After around a decade, an EV battery no longer provides sufficient performance for car journeys. However, they still can retain up to 80 percent of their original capacity, and with this great remaining power comes great reusability. “As the batteries degrade, they lose their usefulness for vehicles,” says Matthew Lumsden, chairman of Connected Energy. “But batteries can be used for so many other things, and to not do so results in waste and more mining of natural resources.” One study ... calculated that a second life battery system saved 450 tons of CO2 per MWh over its lifetime.

Minecraft has established itself as a cultural phenomenon for many reasons: it’s creative, collaborative, and sufficiently facile as to be considered accessible to almost anybody. These benefits ... form the perfect vehicle for Reporters Without Borders’ Uncensored Library, a virtual hub housing a collection of otherwise inaccessible journalism from all over the world, with specific sections devoted to Russia, Egypt, Mexico, Saudi Arabia, and Vietnam. “In Egypt there’s no free information,” Reporters Without Borders media and public relations officer Kristin Bässe tells me. Mexico is the country where journalists are most at risk, she adds, with governmental and cartel interference often culminating in the death of those voices deemed dissident. “It’s a different form of censorship,” Bässe explains. “People don’t want to publish because they’re scared.” “In the Mexico room we built memorials to 12 Mexican journalists who have been murdered,” [said Blockworks managing director James] Delaney. Delaney tells me that the forms of censorship in Egypt are more blatant. “The articles you see in this room are actually banned,” he explains. “If you live in Egypt you’re unable to access them unless you come to our Minecraft server.” This is the case for the Russian, Vietnamese, and Saudi Arabian sections, too. “The content you find in these rooms is illegal, but we can see from the server logins that we’ve already had people from all five of these countries join and read up on this information,” he says.

https://thepulse.one/2022/10/20/a-device-that-literally-generates-electricity...

A study published in Nature in February 2020 entitled “Power generation from ambient humidity using protein nanowires” discovered an interesting way to harvest energy from the environment, creating the potential for another clean power generating system that is self-sustaining. According to the authors, “Thin-film devices made from nanometre-scale protein wires harvested from the microbe Geobacter sulfurreducens can generate continuous electric power in the ambient environment. The devices produce a sustained voltage of around 0.5 volts across a 7-micrometre-thick film, with a current density of around 17 microamperes per square centimetre. We find the driving force behind this energy generation to be a self-maintained moisture gradient that forms within the film when the film is exposed to the humidity that is naturally present in air.” The study also mentions that “connecting several devices linearly scales up the voltage and current to power electronics” and that their results “demonstrate the feasibility of a continuous energy-harvesting strategy that is less restricted by location or environmental conditions than other sustainable approaches.” One of the electrical engineers, Jun Yao, from the University of Massachusetts Amherst, stated that they are “literally making electricity out of thin air.” They are calling it the “Air-gen” and it generates clean energy 24/7, thanks to the electrically conductive protein nanowires produced by Geobacter.

Scientists Have Used Mushrooms to Make Biodegradable Computer Chip Parts

https://www.cnn.com/2022/11/15/world/mushroom-skin-electrical-circuits-scn-sc...

New research has shown that mushroom skins could provide a biodegradable alternative to some plastics used in batteries and computer chips, making them easier to recycle. Researchers from the Johannes Kepler University in Austria were working on flexible and stretchable electronics, with a focus on sustainable materials to replace non-degradable materials, when they made their discovery, published in the journal Science Advances. “There was a fair share of serendipity involved,” Martin Kaltenbrunner ... co-author of the paper, told CNN. At the time, a member of the team had been looking at using fungus-derived materials for use in other areas. This work led to the latest study, which shows how Ganoderma lucidum mushroom skin could work as a substitute for the substrate used in electrical circuits. A substrate is the base of a circuit that insulates and cools the conductive metals sitting on top of it. Typically, they are made of non-degradable plastics, which are discarded after use. The mushroom ... forms a compact protective skin made of mycelium, a root-like network, to protect its growth medium (the wood). The skin has many properties that set it apart from other biodegradable materials, Kaltenbrunner said, “but most importantly, it can simply be grown from waste wood and does not need energy or cost intensive processing.” “Our mycelium ... can last a long time if kept dry, but in just a standard household compost, it would degrade entirely within two weeks or less,” he added.

Mushroom walls and waste-fuelled stoves: inside the self-sufficient home of tomorrow

Joost Bakker believes a house can be more than a place to live: it can be a self-sustaining weapon against the climate crisis. A new Australian documentary explores his bold blueprint. Bakker – a multi-disciplinary designer, no-waste advocate and the film’s eponymous protagonist – has long been something of a provocateur. In 2020, the Dutch-born, Australian-raised designer’s two decades of high-concept sustainability projects came to a head when he hit go on the construction of Future Food System. Erected in one of the busiest areas of Melbourne, the off-grid, three-storey house and urban farm produced all of its own power and food. Even the cooking gas was generated from human and food waste. “We can have it all,” Bakker [says]. “We can have houses covered with biology, plants, ecosystems and waterfalls. It’s not necessary for us to be destroying the planet or killing each other with materials that are making us sick. The infrastructure is already there. It’s just about reimagining our suburbs and reimagining our buildings.” Shadowing Bakker throughout the project from set-up to pack-down, was film-maker Nick Batzias ... who squeezes plenty of action into the pacy 90-minute documentary. The bulk of the film focuses on the building’s green-thinking initiatives. Steam from the showers is used to grow mushrooms; the foundation-less building is anchored by self-watering garden beds filled with 35 tonnes of soil.

https://www.goodnewsnetwork.org/company-mimics-spiders-to-create-faux-silk-10...

By mimicking how a spider spins silk at room temperature, an Oxford University venture has created a high performance, biodegradable textile that is 1,000 times more efficient than current methods for making man-made fabrics, which emit tons of carbon. Over the course of millions of years, spiders have evolved the ability to create one of the world’s strongest and most adaptable materials—silk. The secret to a spider’s ability to create silk lies within their spinnerets, a specialized organ that turns the liquid silk gel within the spider’s abdomen into a solid thread. After years of research into this unique mechanism, Spintex has managed to mimic the spider’s amazing ability: The company has created a process to spin textile fibers from a liquid gel, at room temperature, with water and biodegradable textile fibers as the only outputs. Last week, the nonprofit Biomimicry Institute awarded $100,000 to the English researchers, naming Spintex the winner of this year’s Ray of Hope Prize, which honors the world’s top nature-inspired startups. More than 50% of silk’s environmental footprint lies in the raw material processing, which uses thousands of liters of water that must be boiled every day, so it’s very energy intensive. Currently, there are no sustainable alternatives to traditional silk. “Spintex provides the only truly sustainable option for silk production that can produce bers with the quality, performance and luster of traditional silk,” says the company website.

The Amish use tech differently than you think. We should emulate them.
2020-02-17, Washington Post
Posted: 2020-03-09 16:27:14
https://www.washingtonpost.com/opinions/to-learn-how-to-practice-humane-techn...

Technology promised to connect us but divided us instead. As people worry about smartphone addiction and vow to spend less time on their laptops, social media companies are scrambling to placate a world that has caught on to their products ability to turn us against one another, tip elections and even incite violence. The growing anxiety about technology has prompted a humane technology movement among former Silicon Valley insiders disquieted by what their industry has wrought. But theres another group, utterly unconnected to Google or Facebook or Apple, that has been practicing humane technology for generations: the Amish. Each church community of about 30 families ... has latitude in setting its technology boundaries. When a church member asks to use a new technology, the families discuss the idea and vote to accept or reject. The conversation centers on how a device will strengthen or weaken relationships within the community and within families. Imagine if the United States had conducted a similar discussion when social media platforms were developing algorithms designed to amplify differences and then pit us against one another, because anger drives traffic and traffic drives profits. Americans will never abandon technology for a horse-and-buggy life, but millions of us have begun weighing the costs of constant connectivity. When pondering how to strike the right balance, we might do well at least to pause and consider taking a personal version of the Amish approach.

https://www.nbcnews.com/health/health-news/virtual-reality-helps-cure-real-li...

Virtual reality can help act as a do-it-yourself therapist, helping people overcome their fear of heights without a professional at their side, British researchers reported. A half dozen virtual reality sessions over two weeks significantly reduced the fear of heights for more than two-thirds of people who tried it, the team at the University of Oxford reported. Some even ventured onto rope bridges and mountainsides. The outcome results are brilliant. They are better than I expected, [said] Daniel Freeman, the University of Oxford clinical psychologist who led the study team. The team tested 100 volunteers, 49 of whom were given six virtual reality sessions over two weeks. The rest got no treatment. On average, the volunteers had been afraid of heights for 30 years. After six weeks, those who got no treatment remained just as afraid of heights as they had always been. But 34 of the 49 volunteers who did the virtual reality found they were no longer afraid of heights. Real-life exposure to heights has verified this. Afterwards, people even found they could go to places that they wouldnt have imagined possible, such as walk up a steep mountain, go with their children on a rope bridge, or simply use an escalator in a shopping center without fear, [Freeman said]. The software can be whimsical, offering scenarios from walking across a virtual rope bridge to rescuing a cat from a limb. Freeman said the experiences are meant to strongly immerse people in a sensation of height and then encourage them to challenge their reluctance to take part.

Wave-Powered Desalination Promises To Deliver Clean Water To Developing Countries And Island Nations
2019-07-10, Forbes
Posted: 2019-07-22 18:15:17
https://www.forbes.com/sites/natalieparletta/2019/07/10/wave-powered-desalina...

Using the power of ocean waves, innovators from Boston, U.S., have developed a technology that can produce fresh water off-grid and without the costly infrastructure of desalination plants. This invention could help many of the 2.1 billion people around the world who struggle to access safe drinking water, most of those in low-income countries. The technology, Wave2O, was developed by start-up company Resolute Marine Energy. Chief Operating Officer Olivier Ceberio says it targets off-grid coastal communities in developing nations where a solution to persistent water shortages is urgently needed. Importantly, it fills a gaping hole between industrial-scale utilities that are costly and time-consuming to build, and micro-scale solutions for individual households. The only technology currently offered in between involves diesel-powered desalination systems. And Wave2O can be delivered competitively because it uses free energy from a consistent and inexhaustible renewable energy resource: ocean waves, says Ceberio. By eliminating the need for diesel generators, the invention not only saves money but reduces carbon dioxide emissions. Each 4,000 [cubic meter per] day plant that displaces an equivalently sized diesel-powered plant will cut CO2 emissions by 4,300 tons per year, explains Ceberio, the equivalent of taking 936 cars off the road or of the carbon sequestered by 2,070 hectares of forest.

How tech is bringing Israelis and Palestinians together
2019-04-30, BBC

https://www.bbc.com/news/business-48053200

Israel may be known as the Start-up Nation, famed for its tech start-ups that are supported by one of the largest venture-capital industries per capita in the world. But Israeli-Palestinian relations have been relentlessly grim. Initiatives like Tech2Peace are trying to bridge divides between the two communities. The student and volunteer-led programme brings Israeli and Palestinian youths together to learn tech skills - 3D and graphic design, website creation, app development - and to engage in conflict resolution dialogue. [Participant Zada] Haj says she had "zero knowledge" of animation or 3D modelling before, but by the end of the session she was able to turn her ideas into creation and develop skills that would help her get a job. Palestinian entrepreneur Adnan Awni Jaber also says Tech2Peace was the gateway for him to make Jewish friends in Israel. "I believe that technology can break walls between any two sides of the conflict because it's borderless," he tells the BBC. When [Tomer Cohen] and his Israeli and Palestinian co-founders were thinking of ways they could foster long-term partnerships between youngsters, they came up with the idea of giving them life skills that could enable them to continue working together. "We thought, OK, let's do this with technology and programming," says Mr Cohen. "When young people come to our seminar, they're not thinking, 'OK, you're Palestinian and I'm Israeli,' they're thinking, 'I want to improve my life and you want to, as well. We have something in common'."

Indoor vertical farming startup Bowery is in the process of building a second facility which it claims will be the most technologically sophisticated indoor farm in the world. The operation will be in Kearny, N.J., and grow 30 times more produce than its current indoor farm thats located nearby, and supply 100 types of leafy greens and herbs. Bowery is applying robotics, machine learning, and predictive analytics to the agriculture sector, a segment of the economy that has been slow to adopt technology and digital advancements. Software is the brains of the farm, says Bowery CEO and founder Irving Fain. Small adjustmentswater flow, light intensity, temperature, humiditycan then be made in response to data inputs to impact outcomes like taste and flavor, such as growing a mustard green thats got a spicier pick. These changes get pushed out automatically into our system, says Fain. The precision and level of control is unparalleled. Fain says that Bowery is more than 100 times more efficient than a square foot of farmland, in large part because the startup can grow 365 days a year. Bowery doesnt use any pesticides or agri-chemicals. Normally out in a field that would lead to reduction in yield, but Bowery has more crop cycles per year, grows twice as fast as a field, and has higher yield per crop cycle, says Fain. Its a better product for us and better way of growing and less destructive to the earth, says Fain. Were using technology to grow the purest food possible.

The sprawling, gated campus of the Energy Research Center of the Netherlands (ECN) sits on a spit of land about an hour north of Amsterdam. In a nearby control room, engineers ... were working on one of clean energys intransigent problems: how to turn waste into electricity without producing more waste. Decades ago, scientists discovered that when heated to extreme temperatures, wood and agricultural leftovers, as well as plastic and textile waste, turn into a gas composed of underlying chemical components. The resulting synthetic gas, or syngas, can be harnessed as a power source, generating heat or electricity. But gasified waste has serious shortcomings: it contains tars, which clog engines and disrupt catalysts, breaking machinery, and in turn, lowering efficiency and raising costs. This is what the Dutch technology is designed to fix. The MILENA-OLGA system, as they call it, is a revolutionary carbon-neutral energy plant that turns waste into electricity with little or no harmful byproducts. The MILENA-OLGA process ... is 11 percent more efficient than most existing energy-from-waste plants and over 50 percent more efficient than incinerators of a comparable scale. The process also emits zero wastewater and produces no particulates or other pollutants. Just 4 percent of the original material is left over as inert white ash, which can be used to make cement.

A microbrewery in Delray Beach, Florida has devised a crafty solution to plastic six-pack rings that often wreak havoc on marine wildlife. After years of research and development, Saltwater Brewery has introduced six-pack rings made of wheat and barley. The brewery developed the rings with a start-up company called E6PR. Whereas plastic rings can become tangled in the wings of sea birds, warp the shells of growing sea turtles and choke seals, Saltwater Brewery's new rings are not only biodegradable but also perfectly edible. "E6PR hopes other breweries - both small and large - will buy into the new rings and help bring costs down," Nola.com reports. The Louisiana State University (LSU) reports that the Gulf of Mexico has one of the highest concentrations of marine plastic in the world. Every net that LSU dipped into the Gulf's water came up with some form of plastic. "We found it every time," LSU's Mark Benfield [said]. E6PR is testing the edible rings with "a select group of craft breweries," but the company is not yet ready to discuss specifics.

Incredible device that generates electricity out of thin air by harvesting energy from changes in temperature
2018-02-27, Daily Mail
Posted: 2018-03-05 05:26:11
http://www.dailymail.co.uk/sciencetech/article-5440613/Incredible-device-gene...

A miraculous device that can generate electricity seemingly out of thin air has been developed by engineers. Called a thermal resonator, it relies on fluctuations in temperature between day and night to produce electricity. It can be used without the need for sunlight, batteries or wind, making it ideal for situations where these resources can't be relied upon. The technology has the potential to power sensors and communications devices for years without the need for batteries. Experts at the Massachusetts Institute of Technology's (MIT) department of chemical engineering are behind the find. Their gadget is a twist on a thermoelectric generator, which creates power when one side of the device is a different temperature from the other. Researchers say that the power levels generated by the new system so far are modest. However, it outperformed a commercially available pyroelectric material - an existing method for converting temperature fluctuations to electricity - by 300 per cent. Professor Michael Strano, who led the study, said: 'We basically invented this concept out of whole cloth. 'It's something that can sit on a desk and generate energy out of what seems like nothing. 'We are surrounded by temperature fluctuations of all different frequencies all of the time. These are an untapped source of energy.' Such systems could provide low-power but long-lasting energy sources for landers or rovers exploring remote locations, including other moons and planets, says Volodymyr Koman, an MIT postdoc and co-author of the new study.

William Andregg ushers me into the cluttered workshop of his startup Fathom Computing. Inside [a bulky black box is] a prototype computer that processes data using light, not electricity, and its learning to recognize handwritten digits. In other experiments the device learned to generate sentences in text. Andregg claims this is the first time such complex machine-learning software has been trained using circuits that pulse with laser light, not electricity. The company is working to shrink its [prototype], which covers a few square feet of workbench, to fit into a standard cloud server. Fathom hopes the technology will become one of the shovels of the artificial-intelligence gold rush. Tech companies, particularly large cloud providers like Amazon and Microsoft, spend heavily on computer chips to power machine-learning algorithms. Fathoms founders are betting this hunger for more powerful machine learning will outstrip the capabilities of purely electronic computers. Optics has fundamental advantages over electronics, says William Andregg. Youre already reaping the benefits of using light instead of electricity to work with data. Telecommunications companies move our web pages and selfies over long distances by shooting lasers down optical fiber. Optical computers arent likely to power your laptop or smartphone any time soon. Fathoms prototype is still too bulky, for one thing. But the technology does look to be a decent match for the main work that chips perform in AI projects based on artificial neural networks.

"Welcome to the Blockchain! Your voice is worth something," states a webpage of Steemit, the social network built on a blockchain that's now exploding with popularity. Steemit ... supports community building and social interaction through cryptocurrency rewards and a reputation or influence-based system, known as Steem Dollars and Steem Power. Ned Scott, CEO and co-founder of Steemit, told IBTimes: "If you think about the existing models - Facebook, Twitter, Instagram - these are platforms that invite people to come and do all this work so that their shareholders, who are not necessarily contributors make all this money. "Our platform is a cooperative version of a social network which is more intuitive, and a more shared, community-driven approach, and that's why our early user base is growing. We are completely open source." Steemit grew out of a long process set in motion by gifted developer and co-founder, Daniel Larimer. It evolved from the idea of a decentralised exchange ... to a later exploration of blockchain-based mutual aid and micro-insurance, with a forum added for users to interact and compare notes. It does away with traditional cryptocurrency barriers to entry, like having to go and buy coins at an exchange. Scott said everyone is rewarded one way or another. People who post content actually get rewarded [with Steem, a currency whose value] is split between tradability and reputation. Steem is currently the third most valuable cryptocurrency in the world.

Note: Unlike other social media platforms such as Facebook, Steemit is technically impossible to censor and is owned by everyone that uses it. Explore a treasure trove of concise summaries of incredibly inspiring news articles which will inspire you to make a difference.


How solar brought Muslims and Jews together in one West Bank village

http://www.csmonitor.com/World/Global-News/2016/0515/How-solar-brought-Muslim...

A solar project funded and operated by both Jews and Muslims is shining some light on Auja, a small Palestinian town located in one of the most controversial territories on Earth. The $100,000 project is harnessing solar energy to power the drawing of water from deep underground to irrigate a grove of palms growing the prized Medjool dates. It is the first large project to be funded by both Jews and Muslims in the United States including former New York City Mayor Michael R. Bloomberg and to be operated by Israeli Jews and Palestinian Muslims on the ground. The solar array is providing an economic boost to 45 farming families in this town of 5,000 Palestinians on the eastern flank of the West Bank who struggle with scarce water and unreliable and expensive electricity. Ben Jablonski ... is leading the project through a nonprofit he founded called Build Israel Palestine. Mr. Jablonski, who is Jewish, started the organization in 2014 with Tarek Elgawhary, an Egyptian Muslim religious scholar in Washington, D.C. who also runs Coexist, an educational nonprofit. Jablonski gave up his board seat with the Jewish National Fund, a nonprofit infrastructure developer that has limited but controversial involvement in West Bank settlements, in order to meet the demands from the Auja community, which insisted that donors and engineers involved in the project have no connections to Israeli settlements. Build Israel Palestines work focuses on providing Palestinians access to water, and doing so by bringing Muslims and Jews together.

http://www.cnn.com/2013/04/04/us/cnnheroes-pyfrom-brilliant-bus/index.html

Working as a guidance counselor five years ago in Palm Beach County, Estella Pyfrom noticed that [few] students had access to a computer after school. "They needed food. They needed to pay their mortgage or their rent," said Pyfrom, a former teacher. Without a computer at home, or reliable transportation to get to a computer, Pyfrom feared that many of these students would get left behind. So she bought a bus, filled it with computers and brought technology to the kids. Her mobile computer lab, Estella's Brilliant Bus, has provided free, computer-based tutoring for thousands of students since 2011. Pyfrom ... retired in 2009 and used money from her savings to buy the bus, [which] is outfitted with 17 computer stations that are connected to high-speed Internet via satellite. Emblazoned on its side are the words "Have Knowledge, Will Travel" and "We bring learning to you." The bus travels to schools, shelters and community centers throughout the county. Pyfrom and her team provide about 8,000 hours of instruction to at least 500 children a year. She also partnered with a community nonprofit to help provide meals to 3,000 residents each month. To keep up the momentum of her efforts, Pyfrom has continued to pour her savings into maintaining and modifying her bus, so far spending about $1 million, she says. "I don't think I'm going to get tired," she said. "I'm constantly charged up. I look at the faces of the children and I get energized."

The tech startups that believe happiness can be found in an app
2013-07-29, The Guardian (One of the UK's leading newspapers)
Posted: 2013-09-24 10:00:52
http://www.theguardian.com/sustainable-business/technology-happiness-found-in...

To the startups behind a series of new phone and tablet apps designed to make you smile, happiness is big business. Happier Inc ... launched a phone app in February encouraging users to reflect upon and share pleasant everyday moments. Built around the theory that writing down a nice thought is good for you and that positivity is contagious, the app is about helping consumers take stock of what's good in their life now and to treasure it, says [founder Nataly Kogan]. In the process, she is hoping to prove the technology haters wrong and remedy the negativity on social networks. "On Facebook, we're all bragging," she says. We present the best versions of ourselves and then our friends compare the real versions of their lives to our best versions, and that is depressing." Happier is not alone however. An array of other apps such as Mappiness, Happy Apps and Live Happy have come onto the market in the last couple of years, variously promising to track, share or enact moments of joy. John C Havens, author and founder of non-profit, H(app)athon Project, which uses mobile data to provide recommendations for volunteerism in the local community, suggests digital tools designed to measure contentment redress an imbalance in society where economic data is too often prioritised over social data. "There is real joy in discovery and introspection and reflection, which is something that we lack in modern society where we are so obsessed with productivity," he says. "If you allow yourself on a personal level, that self-reflection, as aided by these technologies, the hope is that you will discover areas of your life you have not been giving credit to."

Pee power! African teens create urine-fueled generator
2012-11-08, CNET
Posted: 2013-02-25 16:20:49
http://news.cnet.com/8301-17938_105-57547296-1/pee-power-african-teens-create...

Four teenage African girls have come up with a urine-powered generator ... which they claim generates one hour of electricity from one liter (about a quart) of urine. The pee-powered product made its debut at Maker Faire Africa in Lagos, Nigeria. Urine is put into an electrolytic cell, which separates out the hydrogen. The gas cylinder pushes hydrogen into a cylinder of liquid borax, which is used to remove the moisture from the hydrogen gas. This purified hydrogen gas is pushed into the generator. The girls will probably be famous chemists one day, in any case, but they aren't the first to propose urine (or more solid human and animal waste) as a possible alternative fuel. Last year, in one example, researchers from Ohio University came up with their own technology for extracting hydrogen from urine. Doing so, they say, requires less power than plucking it from water, as hydrogen can be separated more easily from the ammonia and urea chemical compounds present in pee. The four African teens likely are the youngest researchers yet to dabble in pee as power. Skepticism aside, can we all just agree that the foursome should be lauded for their efforts to find alternative power sources on a continent that could really use them?
