Weekly Solarpunk, of 14 July: Reused Wind Turbines, Solar Trikes in Cuba, AI Cost Backlash, Airport Solar Canopies
Weekly Solarpunk for 14 July follows 6 future-facing stories and member reactions, including Reused Wind Turbines, Solar Trikes in Cuba, AI Cost Backlash, Airport Solar Canopies. 1. Reused Wind Turbines The story is about old Dutch wind turbines getting a second life in Ukraine instead of being scrapped. According to Euromaidan Press, Ukrainian buyers are refurbishing turbines that are no longer efficient enough for the Netherlands and using them to build more scattered power generation on a grid repeatedly damaged by Russian strikes. Source link 2. Solar Trikes in Cuba Cubans are increasingly using solar-equipped electric tricycles because the island's fuel shortages and blackouts have made conventional transport unreliable. According to the Associated Press, these mostly Chinese-made three-wheelers now carry passengers and goods in Havana, cost roughly two to four thousand dollars, and can be upgraded with solar panels so they can charge off the strained grid. Source link 3. AI Cost Backlash This story is about a growing backlash to the idea that companies can replace workers with AI at little cost. According to a Yahoo Finance article shared in the post, the problem is that AI data centers are so expensive to build and run that providers may need to charge fees high enough to wipe out the promised labor savings. Source link 4. Airport Solar Canopies Indianapolis International Airport is installing solar panel canopies over part of a parking lot so the same space can shade cars and help power the terminal. According to local reporting, the canopy project adds to a much larger solar buildout already on airport land and is meant to cover a meaningful share of terminal electricity rather than address aviation emissions by itself. Source link 5. Solar Overtakes Gas New analysis says solar is pulling ahead of gas in the global power mix, with 61 of 124 gas-generating economies already past peak gas-fired electricity. According to Electrek's summary of an Ember report, gas's share of global electricity fell from 23.9 percent in 2020 to 21.8 percent in 2025, while solar added 636 terawatt-hours last year versus just 38 for gas. Source link 6. Battery Supply Glut China may be on track to build more battery manufacturing capacity than the whole world can use by 2030, and that forecast drove this discussion. According to pv magazine, a US think tank projects Chinese cell production capacity of 5,862 to 6,720 gigawatt-hours by the end of the decade, against expected global demand of 4,000 to 5,100.

Weekly Solarpunk, of 12 June: River Cleanup Trespassers, Safer Water Supercapacitors, Tribal Dam Settlement, Solar Surplus Bottleneck
Weekly Solarpunk for 12 June follows 6 future-facing stories and member reactions, including River Cleanup Trespassers, Safer Water Supercapacitors, Tribal Dam Settlement, Solar Surplus Bottleneck. 1. River Cleanup Trespassers A video highlighted people who trespass along a London river to remove trash themselves when they believe official cleanup is not happening. According to Channel 4 News, the report follows litter pickers who are breaking the law in order to clear waste from the riverbank. Source link 2. Safer Water Supercapacitors Researchers say water trapped inside one-nanometer clay channels can act as the working electrolyte in a supercapacitor, pointing to a potentially safer way to store energy. According to Tech Xplore's summary of a Nature Communications paper led by Dr. Vasily Artemov at Hamburg University of Technology, the device combines water, clay, and graphene, reaches up to 1.6 volts, and stayed stable for more than 60,000 charge-discharge cycles in lab tests. Source link 3. Tribal Dam Settlement Seattle has agreed to a $1.35 billion settlement with three tribes over the Skagit River dams that powered the city's growth while cutting off salmon and damaging Indigenous communities. According to Inside Climate News, the deal is part of relicensing the dams, includes nearly $1 billion for fish passage, and is expected to raise electricity rates over time. Source link 4. Solar Surplus Bottleneck China has built so many solar panels that factories are sitting idle even as the world says it needs cheaper clean energy. In a Financial Times opinion essay, Adam Tooze argues that Chinese manufacturers can now produce about 1,000 gigawatts of panels a year, prices have crashed, and more than 40 companies have already failed, been bought out, or delisted. Source link 5. Swarm River Power This story is about a modular river power system that claims to generate hydroelectricity without building a dam. According to the linked video from German Science Guy, the first so-called swarm power plant is said to produce about 1.5 gigawatt-hours of electricity per year by placing multiple smaller units in moving water rather than blocking the whole river. Source link 6. Repair Cafe Revival Repair Cafes are being presented as a practical alternative to throwing away broken household goods, with one event in New Paltz, New York, fixing most of what people brought in. According to the Associated Press, volunteers at that gathering repaired 71 of about 85 items, from electronics and clothing to clocks and photos, while the movement that Martine Postma started in the Netherlands in 2009 now spans roughly 4,000 cafes.

Weekly Solarpunk, of 11 June: Arco Climate Film, Seattle Dam Settlement, Solar Panel Surplus, Swarm River Power
Weekly Solarpunk for 11 June follows 6 future-facing stories and member reactions, including Arco Climate Film, Seattle Dam Settlement, Solar Panel Surplus, Swarm River Power. 1. Arco Climate Film A French indie science-fantasy film called Arco is drawing attention as a rare big-screen story built around future climate projections, with a 2075 setting that leaves room for speculative time travel and crystal-based energy ideas. The original poster calls it a ten-out-of-ten work reminiscent of Ursula K. Source link 2. Seattle Dam Settlement Seattle City Light has agreed to pay about one point three five billion dollars to three Skagit River tribes as part of relicensing three hydroelectric dams that have powered the city for more than a century. According to reporting shared in the thread from Inside Climate News, nearly one billion dollars would go toward fish passage, likely trucking young salmon around the dams and returning adults upstream to spawn, while the rest would fund reservation projects, cash payments, and delta habitat work. Source link 3. Solar Panel Surplus China is producing so many solar panels that some factories are sitting idle while clean power remains within reach, according to a Financial Times article shared under the headline that wasting the surplus is madness. The post itself carries no summary beyond the link, so the thread's substance lives almost entirely in reader reactions to that reported mismatch between manufacturing capacity and deployment. Source link 4. Swarm River Power Engineers have built what is being called the world's first swarm power plant, a modular river-energy system that reportedly produces about one point five gigawatt-hours of electricity per year. A linked video from the channel German Science Guy describes small hydro units spaced along a river rather than walled behind a single dam, and the original poster highlights that as an alternative to conventional hydro that blocks fish migration and reshapes whole ecosystems. Source link 5. Community DIY Store Someone in a poverty-stricken community without reliable drinking water is planning a small local business selling DIY gardening kits, homestead project guides, and art or literature aimed at self-sufficiency, and wants to know whether an online store would also be welcome or feel inappropriate. The post frames the work as practical aid for neighbors who need tools and knowledge more than branding, but the question of commerce immediately splits the responses. Source link 6. Backyard Battery Builder A post celebrates Ben, a YouTube creator known as the Backyard Scientist, for DIY projects that include cheap redox batteries and other hands-on builds the average person could try at home. The original message is enthusiastic but vague, calling him a hero of the future without linking to a specific video, which quickly draws a corrective comment: "Missing a link?

Weekly Solarpunk, of 07 June: Albania Wetland Defense, App-Locked E-Bike, Food Forest Network, MOF COF Chemistry
Weekly Solarpunk for 07 June covers a wetland defense campaign, app-locked repair culture, community food forests, new materials chemistry, a printable generator, and a universal wellbeing proposal. 1. Albania Wetland Defense Residents and conservation groups in Albania are trying to stop luxury resort development in the Vjosa-Narta wetland complex, arguing that protected coastal habitat is being turned into private tourism infrastructure. According to a June 4, 2026 Guardian report linked in the post, protests have grown around a Jared Kushner-backed resort proposal while local groups circulate petitions and conservation briefings. Source link 2. App-Locked E-Bike This story is about a locked-down e-bike that needed heavy hacking and rewiring because basic functions were tied to a phone app that was no longer supported. According to a Berm Peak video, even the headlights depended on that app, so the repair becomes a case study in what happens when ordinary hardware is made subordinate to brittle software controls. Source link 3. Food Forest Network Project Ubuntu and the Big Green Web proposes a network of free, community-governed food forests powered by renewable energy to address food insecurity in communities of color. According to the linked paper, the model combines food sovereignty, environmental justice, and mutual aid while centering Black, Brown, and Indigenous knowledge in local food production. Source link 4. MOF COF Chemistry A post spotlights chemist Omar M. Yaghi's work on metal-organic and covalent organic frameworks, materials designed as open crystalline lattices for storage, filtration, and other uses. The linked talk presents reticular chemistry as a promising platform, but the thread itself offers almost no scrutiny of cost, durability, or deployment timelines. Source link 5. Printable Generator This story is about a maker who built a third-generation modular, 3D-printable bench-top generator intended for DIY wind and micro-hydro experiments. In an accompanying video, the builder says the latest version can produce at least ten watts line to line and uses interchangeable printed coil bobbins, called ModuCoils, so individual stator coils can be swapped for repair, recycling, or customization. Source link 6. Universal Wellbeing Plan A paper argues that the United States could fund universal access to healthcare, housing, education, energy, transportation, water, food security, and environmental protection for about $2.095 trillion a year, or 7.5 percent of GDP. Posted on Academia.edu, it frames the main obstacle as political resistance rather than missing resources. Source link That's it for today.

Weekly Solarpunk, of 05 June: Wealth and Climate Plan, Plant-Based Burgers Win, Australia Gas Decline, Offshore Solar Tradeoffs
Weekly Solarpunk for 05 June follows 6 future-facing stories and member reactions, including Wealth and Climate Plan, Plant-Based Burgers Win, Australia Gas Decline, Offshore Solar Tradeoffs. 1. Wealth and Climate Plan Thomas Piketty's new plan argues that a decent, lower-carbon life for most people is achievable through large-scale redistribution and new global institutions meant to tackle inequality and climate breakdown together. According to the linked Guardian essay and the report it points to, the proposal includes steep taxes on extreme wealth and a Global Justice Fund, but in this thread the plan is discussed more as a political blueprint than as proven policy. Source link 2. Plant-Based Burgers Win Vegan burger patties reportedly outperformed beef patties in a head-to-head consumer test in Germany, turning a food-quality comparison into a bigger argument about how fast plant-based substitutes are improving. According to Vegan Horizon’s summary of the Stiftung Warentest test, seven of ten vegan patties rated good versus three of ten beef patties, with the vegan options also described as cheaper, leaner, and free of the bacterial contamination found in some beef samples. Source link 3. Australia Gas Decline Australia's gas use has peaked and entered what a new report describes as structural decline. According to the Guardian's summary of a Grattan Institute report, residential gas use peaked in 2020, gas-fired electricity demand is down 11 percent since 2014, manufacturing use has been falling since the early 2000s, and LNG exports likely peaked in 2022. Source link 4. Offshore Solar Tradeoffs An ocean-based solar farm in Taiwan is reportedly outperforming land-based solar installations. According to the New Scientist report linked in the post, the appeal is straightforward: offshore space can be vast, even if the thread itself does not provide much technical detail beyond the headline claim. Source link 5. Iron Flow Batteries Nighthawk in Light's new video explores electrochemically producing iron from magnetite and using a similar setup as a low-tech iron flow battery. According to the video and the post description, the appeal is that this approach could cut the energy use and emissions associated with coal- or charcoal-based iron smelting, but those broader claims are still mostly presented as a promising demonstration rather than settled evidence. Source link 6. Welsh Solar Biodiversity A 57 megawatt solar and storage project in Wales has been approved with a promise to power about 27,000 homes while delivering a claimed 64 percent biodiversity net gain. According to the linked industry report, the project is being presented as a case where new renewable infrastructure and habitat restoration can be planned together, though the post itself says the real test is whether those gains are delivered in practice. Source link That's it for today.

Weekly Solarpunk, of 02 June: Babcock Ranch, Rural Community Logistics, Forgotten Solar Vision, Solar Siting Tradeoffs
Weekly Solarpunk for 02 June follows 6 future-facing stories and member reactions, including Babcock Ranch, Rural Community Logistics, Forgotten Solar Vision, Solar Siting Tradeoffs. 1. Babcock Ranch A Florida development called Babcock Ranch is being presented as America’s first solar-powered town, with the article framing it as a model for a cleaner future. According to Islands, the town sits between Naples and Sarasota and is marketed as the “homeland of tomorrow,” built around solar power and resilience. Source link 2. Rural Community Logistics A post shared a comic arguing that rural life and resilient infrastructure depend on community, not just aesthetics. According to the comic, the hard part is the logistics under the hood: getting solar panels, batteries, farms, repairs, and the people to maintain them. Source link 3. Forgotten Solar Vision The post points to an article about William Adams, a Bombay bureaucrat whose early solar vision was sidelined by colonial conservatism, raising the idea that a more solar future had already been imagined and then blocked. According to The Conversation, Adams belongs to a longer, mostly forgotten lineage of solar experimenters that the piece uses to argue that cleaner energy was not a purely modern invention. Source link 4. Solar Siting Tradeoffs The post argues that solar power can still meet midcentury climate targets, but only if planners confront the land trade-offs between energy, agriculture, and biodiversity. According to Adam Gallaher, New York could technically site enough utility-scale solar to hit its goals, but where that solar goes matters. Source link 5. East African E-Bikes The post shares a CNN video about the business of electrifying motorbikes in East Africa, focusing on Ampersand’s work in Rwanda and the idea that cleaner transport can grow from the ground up. According to CNN, the story treats this as a practical business problem as much as a climate one, with infrastructure, batteries, and rider economics all tied together. Source link 6. Underground Bike Parking This post shares a video about underground bike parking in Amsterdam and treats it as a concrete example of how a city can make cycling easier without giving up dense urban space. According to Not Just Bikes, the video highlights how the parking is built into the city rather than tacked on as an afterthought. Source link That's it for today.

Weekly Solarpunk, of 31 May: Solar Siting Backlash, Air-to-Water Material, Cheaper Lithium Extraction, Beaver Flood Control
Weekly Solarpunk for 31 May follows 6 future-facing stories and member reactions, including Solar Siting Backlash, Air-to-Water Material, Cheaper Lithium Extraction, Beaver Flood Control. 1. Solar Siting Backlash A study reported in Electrek says most large US solar projects do not trigger the backlash people often expect. According to the writeup on a UMass Amherst study, opposition seems less widespread than the loudest local fights suggest, though the result still depends on where projects are built and who benefits. Source link 2. Air-to-Water Material A water-harvesting material drew attention because it can pull moisture from air without electricity, then release that water when warmed by sunlight or low-grade heat. According to the paper linked in the post, the material is a zirconium-based metal-organic framework, and commenters noted that the metal is relatively common. Source link 3. Cheaper Lithium Extraction MIT researchers reported a low-cost way to pull lithium out of rock, a process that could make a key battery material easier to obtain. According to MIT, the method centers on aqueous ammonium fluoride, which is part of why readers immediately focused on handling, safety, and whether the chemistry is practical outside a lab. Source link 4. Beaver Flood Control Britain is trying to use beavers as a flood-control tool as heavier rains keep overwhelming rivers and drainage systems. According to NPR, the idea is to let beavers and their dams slow water, spread it into wetlands, and reduce downstream flood peaks. Source link 5. Philippines Rooftop Solar A new analysis says rooftop solar in the Philippines is moving from niche to practical fast enough to help ease the country’s power emergency. According to Ember, rising electricity prices and falling equipment costs have cut the payback period for a residential system to about 3.1 years, while estimated rooftop capacity has nearly doubled from 721 MW in early 2025 to around 1,300 MW by early 2026. Source link 6. Rooftop Intensive Care A London hospital has opened what appears to be the UK’s first rooftop intensive care ward, putting critically ill patients outdoors without disconnecting them from life-support treatment. According to the BBC, King’s College Hospital built the ward with space for a handful of beds, weatherproof medical equipment, and planted garden areas so patients can get fresh air and daylight while still being monitored.

Weekly Solarpunk, of 29 May: Climate Scenario Shift, Earth-Sheltered Housing, Underwater Biospheres, Private Nature Reserve
Weekly Solarpunk for 29 May follows 6 future-facing stories and member reactions, including Climate Scenario Shift, Earth-Sheltered Housing, Underwater Biospheres, Private Nature Reserve. 1. Climate Scenario Shift Scientists have pushed the worst-case climate scenario off the table, but the article argues that this is only a sign of partial progress, not safety. According to The Conversation, action has reduced the odds of the most extreme path, yet the next few years still determine whether the world lands in a much harsher future or something closer to the best case. Source link 2. Earth-Sheltered Housing The post highlights a concrete, partially buried home as a practical answer to tornadoes and extreme heat. According to Kirsten Dirksen's video, the design uses earth as insulation and protection while also lowering heating and cooling costs. Source link 3. Underwater Biospheres The post points to Italy's underwater biospheres, called Nemo Gardens, and asks how they might compare with liveaboard stories in fiction. According to the linked ScienceDirect paper, the concept has been around since 2012, which is part of why the idea feels more developed than a casual novelty. Source link 4. Private Nature Reserve An Australian billionaire technology investor and his partner are donating $10 million to buy 7,000 hectares of cattle and logging land in the Great Dividing Range and turn it into a nature reserve. According to the article, the plan would protect tall moist forest, rainforest-clad gorges, wild rivers, and threatened species, but commenters mostly treated it as a small good outcome wrapped in a larger problem. Source link 5. Renewables Beat Gas Wind and solar generated more electricity than gas worldwide in April 2026 for the first time, a milestone reported by Ember Energy. According to Ember Energy, the monthly crossover shows renewables briefly outpacing gas on a global basis, though the post itself does not add extra detail beyond the headline. Source link 6. Solar Water Recovery A sun-powered desalination system is being presented as a way to make fresh water while also recovering lithium from seawater or brine. According to Interesting Engineering, the device couples water production with mineral recovery, but the practical scale and economics are still the real test. Source link That's it for today.
