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.

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.

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 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.

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.

Bitcoin usage in emerging markets is increasing rapidly. And while it’s true that Bitcoin can be a better alternative for unbanked peoples who don’t have the means, access, or even the basic proof of identity to open a bank account, it turns out its biggest benefit today for many people is that Bitcoin is censorship-resistant. In other words, government cannot throttle, control or monitor your behavior as they can in the legacy financial world. In 2020, protests against the government erupted in Lagos and across Nigeria because of the brutal and illegal actions of a unit in the police force. Within days, groups supporting the protesters had their bank accounts frozen. With no other option, they turned to Bitcoin, raising funds that sustained the movement. Peer-to-peer Bitcoin transactions can be zero-fee, a big break from the much higher fees many in Africa are forced to pay for basic financial services, such as those for remittances, which are on average closer to 9%. Alex Gladstein, chief strategy officer for the Human Rights Foundation, has identified a number of other countries, including China, Russia, Belarus, and Myanmar, where the government uses the monetary and banking systems to silence dissidents. Recent deplatforming by big social media companies of certain groups and individuals ... has raised concerns about similar risks in financial services, where banks can limit access to bank accounts, credit cards, and so forth.

A project to decentralize the internet that youve never heard of has more capacity than all other blockchain projects put together: 5-10X more, according to its founder. The project is called ThreeFold, and its not your typical blockchain startup. Instead, its a long-term project to rewire the internet in the image of its first incarnation: decentralized, unowned, accessible, free. We have 18,000 CPU cores and 90 million gigabytes, which is a lot of capacity, founder Kristof de Spiegeleer [said]. Less than 20 companies actually own more than 80% of the internet capacity, which is the storage and the compute. It really needs to be something like electricity. It needs to be everywhere and everyone needs to have access to it. It needs to be cost effective, it needs to be reliable, it needs to be independent. That would be a fundamentally different kind of internet: one we all collectively own rather than just one we all just use. It requires a lot of different technology for backups and storage, for which ThreeFold is building a variety of related technologies: peer-to-peer technology to create the grid in the first place; storage, compute, and network technologies to enable distributed applications; and a self-healing layer bridging people and applications. Oh, and yes. There is a blockchain component: smart contracts for utilizing the grid and keeping a record of activities. So ... you have people providing actual tangible services for others in exchange for some degree of cryptocurrency reward.

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.

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.

There is one thing that practically everyone can agree on: politics has become bitterly divided. Yet what if it doesn't need to be this way? For the last five years, Taiwan has been blending technology with politics to create a new way of making decisions. And with certain limits, it has found consensus where none seemed to exist. Taiwan's burgeoning scene of civic hackers ... were invited to join the government. Their creation was called vTaiwan - with the "v" standing for virtual - a platform where experts and other interested parties can deliberate contentious issues. It works by first seeking to crowdsource objective facts from those involved. Then users communicate with each other via a dedicated social media network called Pol.is, which lets them draft statements about how a matter should be solved, and respond to others' suggestions by either agreeing or disagreeing with them. Once a "rough consensus" has been reached, livestreamed or face-to-face meetings are organised so that participants can write out specific recommendations. Pol.is lifted everyone out of their echo chambers. It churned through the many axes of agreements and disagreements and drew a map to show everyone exactly where they were in the debate. There was no reply button, so people couldn't troll each other's posts. And rather than showing the messages that divided each of the four groups, Pol.is simply made them invisible. It gave oxygen instead to statements that found support across different groups as well as within them. "Change the information structure," Colin Megill, one of its founders, told me, "and you can tweak power". Rather than encourage grandstanding or the trading of insults, it gamified finding consensus. "People compete to bring up the most nuanced statements that can win most people across," Tang told me. "Invariably, within three weeks or four ... we always find a shape where most people agree on most of the statements, most of the time."

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.

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'."

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.

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.

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.

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.

In 2016, a coalition of media, tech, and community organizations launched the Equitable Internet Initiative, a project that will result in the construction of wireless broadband internet networks across three underserved Detroit neighborhoods. Leading the initiative is the Detroit Community Technology Project, a digital justice project sponsored by Allied Media Projects. “During the economic and housing crisis, communities had to fend for themselves,” [executive director of DCTP Diana] Nucera says. That’s why, she explains, “we developed this approach called community technology.” The coalition raised just under $1 million from local and national foundations. Funds were used to hire employees, buy equipment, and internet bandwidth. They purchased three discounted wholesale gigabit connections from Rocket Fiber, a Detroit-based high-speed internet service provider. Their contract with Rocket Fiber allows the coalition to share its connection with the community—a provision not allowed by other companies. Each neighborhood is represented by a partnering organization, whose locale is used as the central connection hub for service. The community members are responsible for installation. DCTP trains a representative of the partnering organization, who then trains five to seven neighbors to install the equipment. “Being a digital steward was completely out of the range of what I usually do,” [neighbor and digital steward Roston] says. “I was so used to using the internet ... but I didn’t know how internet networks work.” So far, he’s helped with getting 19 of the 50 designated households in the Islandview neighborhood online. The bottom-up approach ... strengthens community relationships, increases civic engagement, and redistributes political and economic power to otherwise marginalized neighborhoods. “If the community has ownership of the infrastructure, then they’re more likely to participate in its maintenance, evolution, and innovation,” [Nucera] explains. “That’s what we believe leads to sustainability.”

More than a billion people in the world go to sleep each night without reliable shelter. But a pair of companies working on solving that believes their model of quickly 3D-printing a one-story house could not only provide merely a roof over the head, but a genuinely great place to live. I took a walk around a demonstration house ... built by Icon, a construction firm, and New Story, a non-profit that sets up housing in the developing world. Later this year, the project will head to El Salvador to build some test homes, with the view to begin work on a community of 100 houses in 2019. "If it does work it could literally change how shelter is created," said Brett Hagler, chief executive and co-founder of New Story. Like small-scale 3D-printing, the system works by slowly adding material, layer-by-layer. In this case, that material is mortar, similar to concrete. The El Salvador project will ... aim to build 100 homes, financed by mostly Silicon Valley-based donors. The houses will not be a hand-out, however. "The families agreed to a no-interest, no-profit mortgage that they will pay over about 10 years," explained Mr Hagler. That works out at about $30 a month. According to the country's economics ministry, the average monthly wage in rural El Salvador is around $360. "That money does not come back to us," he added. "It's kept in a community fund." The fund will go on to pay for more homes in future, or maintenance on existing structures. Mr Hagler said the mortgage model will foster "respect and dignity" within the community.

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.

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.
