A Virtual Power Plant (VPP) is a network that connects homes, farms, and businesses using renewable energy sources like rooftop solar, batteries, heat pumps, and smart appliances. Unlike traditional power plants, a VPP doesn’t rely on one central facility. Instead, it creates a coordinated system where each participant contributes power and flexibility. For rural communities, VPPs offer a powerful solution to increasing energy demand and the challenges posed by severe weather. These systems allow smarter energy management, helping communities stabilize their energy use and reduce their reliance on costly fossil fuels like coal and gas. A standout example comes from Colorado’s Holy Cross Energy. Their Power+ Program offers members affordable, lease-to-own home battery storage systems. These batteries store energy during off-peak hours and release it when demand is high or during outages. This not only saves money but also improves energy security and resilience. Similar success stories are unfolding in Vermont, where Green Mountain Power operates a VPP using Tesla Powerwalls. The program saved millions by strategically using stored energy to offset peak demand. These savings are shared with customers through bill credits, creating a win-win model for utilities and participants. Virtual Power Plants show how local, cooperative solutions can drive a national energy transformation.

REMspace, a California-based neurotech startup, claims to have achieved the first two-way communication between individuals during lucid dreaming. Using specially designed equipment, participants reportedly exchanged a message while asleep—an extraordinary claim that has yet to be peer-reviewed. This milestone, if validated, could mark a turning point in dream research, with REMspace suggesting applications from mental health therapies to skill training. Lucid dreaming ... is the state of being aware that you are dreaming while asleep. While around 50 percent of people report experiencing at least one lucid dream, the idea of communication within such a state is still in its early stages of research. The REMspace team claims they achieved communication between two participants during a lucid dream on September 24, 2024. Participants received random words generated by a server through earbuds while they were dreaming. One participant reportedly repeated the word in their dream, and the second confirmed it after waking. Looking ahead, they claim to be working on enabling more complex forms of dream communication, including full conversations and interactions with external servers. [REMspace founder Michael] Raduga predicts that within a few years, “dream communication will become common.” Until then, the scientific community awaits peer-reviewed evidence to substantiate these intriguing, but currently unverified claims.

Venture into New Mexico's beautifully stark high desert and you may well stumble across some fantastical and unconventional homes – some palatial and sculpturally rounded; others with an ancient temple-like form – that look like they're from a Star Wars movie. Set in and around the town of Taos where they were invented almost 40 years ago, these are Earthships: net-zero, sustainably designed homes built mostly from both natural and waste materials, such as old tyres, empty wine bottles and wood and mud. Earthship construction requires less in the way of toxic or carbon-emitting construction materials like concrete and plastics, and doesn't require precious woodland and other natural resources. An earth berm (a purposefully built bank of soil) surrounds the Earthship on three sides, providing insulating mass that controls temperature. Each has a greenhouse ... either on the north or south side depending on location. Most Earthships are purely solar powered; some also have wind turbines to supplement or a wood-burning stove as back up. Taos has cold snowy winters and often dry, hot summers, but in an Earthship, the internal temperature remains close to 72F (21C) year-round, regardless of outside weather conditions. What does it feel like to stay inside an Earthship? "It feels like you're inside the womb," says Earthship construction manager Deborah Binder. "You feel constantly hugged and snuggled. The temperature is always comfortable."

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.

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.

The arrest of Telegram’s founder and the takedown of Simply Bitcoin’s Youtube channel for violating Youtube’s “harmful and dangerous” policy ... speaks to the power of corporations to mediate the reach of speech. French authorities have claimed that Durov was arrested, for among other things, providing “cryptology” tools. States couch their control of virtual space as an extension of their physical authority. Platforms and individuals are held to account for “crimes” being perpetuated on virtual space. One common thread is ... the idea of “misinformation.” Another is to use the most heinous crimes in a witch hunt - child abuse sexual material for example. Another favorite is “terrorism.” Networks like Bitcoin and Nostr are more needed than ever. They both give people geographic arbitrage, the ability to operate without corporate leadership, and a hedge against state repression. The network cannot be shut down or threatened to change its rules as quickly and as easily as arresting one CEO. Is the idea of “decentralization” possible in a world where states can arrest CEOs and founders? Nothing can prevent somebody from exchanging funds with one another using Bitcoin or expressing something on Nostr. Usage of these networks in a peer-to-peer manner with an array of self-custody wallets and clients shows a popular demand for privacy, encryption, and transmitting value without the prying eyes of the state.

Audrey Tang ... is determined that digital technology will once again become a force for good – a supreme listening tool for humanity, bringing us together by celebrating difference and uniting over what we have in common. Tang spent eight years in Taiwan’s government (the last two as the world’s first minister of digital affairs), putting her theory into practice – and it has worked, from a fantastically efficient response to Covid to countering misinformation about electoral fraud. In 2012, she was part of the digital community that created g0v, pronounced Gov Zero. The project ran in parallel with the official government and was there to support it, even if ministers didn’t initially think so. Through g0v, government websites were examined and rewritten to make them more comprehensible and reachable. “We created a parallel web around which citizens could have a normal conversation. For example, when we did the ministry of education dictionary project, we copied everything from the official website, but turned it into something more accessible.” The thinking is simple, she says: the more clearly information is displayed, the more people will know, and the easier it becomes to have a conversation about what is and isn’t working in a democracy. After g0v came vTaiwan, an online forum allowing people to discuss and petition on issues of public interest. Once there were 5,000 signatures, the petition was taken to the government to be addressed.

Efficiently run food supply chains can positively impact communities and lives across the globe. Real-time tracking supports sustainability, prevents food waste, and ensures compliance with environmental, social and governance (ESG) standards. Communication throughout the supply chain can help producers earn fair compensation for their efforts. Traditional approach to food supply chain management face challenges to efficiency, security and transparency. The consequences can be dire, from food waste to death by contamination. Blockchain technology can provide much-needed transparency, traceability and privacy, as well as co-ordination across disparate parties, enabling greater food access and quality improvements across the global supply chain. Built on a blockchain backend, Silal Fresh adopted a comprehensive traceability solution that utilizes consumer apps, a web-based dashboard, and integration with existing supply chain management systems. This significantly improved identifying and flagging delays in their deliveries, as well as increased satisfaction, trust and brand loyalty. They even added tracking to each piece of produce so that a consumer could pick up a vegetable, scan a QR code, and see that food item's journey. Ultimately, increased transparency and traceability can save lives. With improved traceability, food recalls can happen faster, and the source of contamination can be determined quicker.

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.

Rappler, founded by a group of journalists in 2012, has evolved over time to become one of the leading, most trusted news outlets in the Philippines. In December, the organization launched Rappler Communities, a trailblazing mobile app which it had built and connected directly to their news feed. Built on the open source, secure, decentralized Matrix protocol, the app has the potential to become a global independent news distribution outlet, and promises to pave the way for a “shared reality” — a call [founder and Nobel laureate Maria] Ressa has been making to counter “the cascading failures of a corrupted public information ecosystem.” "At this moment, if news journalism doesn’t come together with communities and civil society that cares about a shared reality, democracy cannot survive," [said Ressa]. "Most important, is that we really have a shared reality. Once our community is set at the matrix protocol chat app, it can then work with other news organizations and become a trusted news distributor. So we will own our distribution, and we could strengthen our communities. Before the end of the year, we aim to have four other new sites, in different parts of the world, federated on this protocol. The matrix protocol is end-to-end encrypted; it is decentralized, similar to the Internet Governance Forum — like having a co-op, it isn’t individually owned, or profit-driven. It’s, literally, a place where we have a shared reality."

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.

Almost two decades after the first iPhone was released, a trend for lower tech devices appears to be taking shape, with a growing minority swapping their smartphones for “dumb phones”. With new models such as the Boring Phone, the trend is partly being fuelled by young people’s suspicion of the data- and attention-harvesting tech they have grown up with, as well as a bid to live more offline. And while smartphones are the obvious target for this trend, the “newtro” (a portmanteau of “new” and “retro”) movement is heralding a revival of analogue media, including cassettes and fanzines, against the backdrop of the enduring, and much-heralded, vinyl boom. While Jess Perriam, 39, had become exhausted by her Instagram feed, she knew she wanted to keep a window into the lives of others. So she turned to Postcrossing, a site that connects people who want to send and receive postcards from strangers around the world. “I still wanted to have that connection with people and learn more about different cultures, but not necessarily while being aggressively marketed at,” she said, adding that she receives “stacks of reading recommendations” through the post. The community has more than 800,000 members across 207 countries, with 77 million postcards received since it launched in 2005. As well as writing to people she has never met, she also corresponds with an old friend in the US. “It forces me to sit down and think, what do I want to communicate to my friend?”

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.

In the final bay of an old, mustard-colored mechanic’s garage in the middle of the Hoopa Valley Reservation’s main settlement is the headquarters of Acorn Wireless. This small, relatively young Internet service provider is owned and operated by the tribe’s public utilities department—an unusual arrangement in the United States, where Internet service is more often the purview of predatory corporations like AT&T and Verizon, whose regional monopolies enable them to charge exorbitant rates for uneven service. Before the launch of Acorn, residents had to choose between a HughesNet satellite connection (more than $100 per month), a bare-bones Starlink kit ($600), unreliable wireless hot spots—or, as was often the case, nothing. Download speeds are nearly 75 percent slower in tribal areas, yet the lowest price for basic Internet service is, on average, 11 percent higher. Acorn’s operation is based on the idea that local, democratic ownership can help address the coverage disparity by eliminating the profit motive. Because it is owned by the tribe and administered by the tribe’s public utilities department, Acorn can focus on equity instead of revenue. Its premium service package is set at $75 a month, [but] most Acorn customers can get service at no personal cost. Hoopa’s experiment in public broadband remains a work in progress, embodying hopes (and facing hurdles) that are shared on tribal lands all over the country.

What if your heating and cooling worked during power outages, and you could count on it becoming more efficient and climate-friendly over time? That's the promise of district heating and cooling or district energy, where entire communities share a heating and cooling system. That allows them to tap into many low-carbon energy sources they couldn't before, more efficiently than any individual building could. As governments look to tackle carbon emissions from buildings — the third largest source in Canada behind the oil and gas industry and transportation — it's an idea that more of them are considering and implementing. Peter Ronson is chief operating officer for Markham District Energy (MDE), a network in a Toronto suburb that heats and cools 14 million square feet in more than 200 buildings, including condo buildings up to 44 storeys tall, a hospital, data centres, hotels and two schools. Some, like the data centres, produce a lot of heat, while others may use lots of hot water. "We got all sorts of stuff on the system," Ronson said. "When [some are] throwing away energy, I can recover and give it to somebody else." That kind of heat-sharing is efficient. Excess heat in the system can also be stored (underground in water or rock, for example) ... and much more cheaply than electricity. All that means converting buildings that burn fossil fuels to district energy can potentially put less strain on the grid than electrifying individual buildings using heat pumps or baseboard heating.

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.

When marine geologist Mick O’Leary showed a group of Australian First Nations Elders a digital model of two ancient watering holes he had recently located—now under 14 meters of ocean—one man perked up, struggled to his feet and began speaking excitedly. Timmy Douglas, had recognized the watering holes as part of a songline he’d known all his life. Songlines involve using dramatic story songs that First Nations people began creating long before the written word as a mnemonic and spiritual system to navigate Australia’s harsh terrain: they would do so by singing the songs as they walked across the land. These songs, which also define groups and laws and impart cultural values, have been passed down from one generation to the next over thousands of years. The connection of the songline to a recent and remarkable archeological find by O’Leary and his colleagues illustrates how First Nations groups and modern scientists are learning to work together—in this case to find evidence of the ancient humans who lived on land that is now underwater, what the Murujuga Elders call “Sea Country.” Such evidence now includes stone tools that the scientists found last year on the ocean floor near the submerged watering holes. O’Leary says that although the research team did not physically follow the songline to make its discovery, he thinks that kind of collaboration might happen in the near future.

Cryptocurrencies represent the marriage of decentralized networks (what we commonly know as the internet today) and assets like money. [Cryptocurrency] uniquely enables new solutions to otherwise intractable technological and social problems. Users often lose control over their personal information online, either all at once through platform hacks or bit-by-bit in the opaque world of online advertising and data brokers. A major issue is that the business model of big tech firms is advertising, creating an incentive to aggregate data into a single database, creating a “honeypot” for hackers. Blockchains can enable a new form of digital identity document for the web. Using these credentials, users can authenticate for services without having to divulge as much personal information. Traditional payment systems are often slow, costly and inaccessible to many. Cryptocurrencies backed by real-world currencies, dubbed “stablecoins,” provide an efficient alternative for global transactions. In 2023, stablecoins accounted for $4.5 trillion of crypto transaction volume on blockchain networks. Even digital payments giant PayPal announced the launch of its stablecoin earlier this year. Traditional humanitarian aid often suffers from inefficiency, lack of transparency and corruption, undermining its effectiveness and trustworthiness. Blockchain offers a solution by providing a transparent, traceable and secure system for humanitarian aid. A recent UN pilot [provided] aid directly to families affected by the war between Russia and Ukraine. The entertainment industry is famously concentrated, causing writers and actors to recently go on strike ... demanding better pay and new contract clauses. Blockchain technology enables more democratic digital economies through non-fungible token (NFTs) marketplaces like Zora, and decentralized autonomous organizations (DAOs) like CreatorDAO, allowing creators and artists to take advantage of online marketplaces and earn fair compensation for their contributions.

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.
Note: The social media platform PeakD is censorship-proof and is governed by network operators who are elected by the community. Explore more positive stories like this in our comprehensive inspiring news articles archive focused on solutions and bridging divides.
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.”
