Weekly Solarpunk, of 28 April: Balcony Solar Rules, Perovskite Lead Tradeoff, Hand Cart Revival, Community Repair Clinics

Weekly Solarpunk for 28 April follows 6 future-facing stories and member reactions, including Balcony Solar Rules, Perovskite Lead Tradeoff, Hand Cart Revival, Community Repair Clinics. 1. Balcony Solar Rules Virginia has become the third state to allow plug-and-play solar, following Maine and Utah, and the linked Forbes piece argues that the change could make small balcony-style systems much easier for ordinary households. According to Josh Pearce, the point is to let residents use compact solar kits without being blocked by local rules, especially in apartments and places with restrictive HOAs. Source link 2. Perovskite Lead Tradeoff A Japanese research team reported an all-perovskite tandem solar cell reaching 30.2% efficiency, which puts the focus on how quickly this material could move from lab results toward practical hardware. According to pv-magazine, the design stacks perovskite layers to capture more of the sun's spectrum than a single-junction cell can. Source link 3. Hand Cart Revival A post argues that hand carts deserve another look as a practical way to move heavy loads on foot. According to the linked article, they can be more agile than bike trailers in tight spaces, and they can handle surprisingly large loads for short-to-medium trips. Source link 4. Community Repair Clinics This post shares a PBS SoCal video about Carlsbad's Fix-It Clinic, where volunteers help people repair broken items instead of throwing them away. According to PBS SoCal, the piece follows a local repair effort built around keeping usable goods in circulation. Source link 5. Honest Organizing Limits A long essay argues that organizing groups fail when they lean on vague slogans, hidden hierarchies, and one-size-fits-all advice. According to Nerd Teacher, telling people to "just go do something" is meaningless unless they are also given support, accommodations, and a realistic sense of what participation actually requires. Source link 6. Heat Adaptive Clothing An Arizona State University research page describes clothing designed to help people stay cooler as temperatures rise, combining new outdoor testing methods with liquid-cooled and evaporation-based garments. According to Konrad Rykaczewski, the project is testing apparel in Arizona heat and asking what practical "cool future fashion" could look like for broader climate adaptation.
