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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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 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.

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.

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.

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.

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.

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?
