2026 Green Powered Challenge: Supercapacitor Enables High-Power IoT

With all the battery technologies and modern low-current sleep modes in most microcontrollers, running a sensor and microcontroller combo off-grid and far away from any infrastructure is usually no…

Electric Wind-Up Plane Uses Supercapacitors For Free Flight Fun

There’s something to be said for a simple wind-up, free flight model airplane. With no controls, it must be built very well to fly well, and with only the limited power of a rubber band, it n…

Solar Supercapacitor Lamp Probably Won’t Get You Saved At Sea

Most solar lights are cheap garbage that exist just to put more microplastics into the environment as they degrade in short order. [Jeremy Cook] built his own solar light, however, and this one mig…

1/2 And Now Something Non - Apocalypse : #Batteries ! At #CES2026
#DonutLab announced the battery to end all batteries (oops). Performance and energy density off the charts. Production and scaling ready. Soon to be shipping in first products…and no publicly available testing data, independent or otherwise. Naturally folks are not ready to buy the bridge, the swamp and the used car all at the same time. The general take from Ima nerd and your not camp is this must be a #Supercapacitor …

Эксперимент показал, что смысл в этом был. Фонарики на ионисторах продолжают светить, когда на ХИТ уже молчат не первый месяц. Сейчас выходил на улицу и обратил внимание, что, несмотря на не солнечную погоду вчера, фонари смогли набрать достаточно энергии и светят до утра.

Жаль что на маркетплейсах такие конденсаторы пропали, купил бы ещё. И мысль докупить комплект на 16В на солнечную станцию осталась.

High-performance supercapacitor made from upcycled water bottles

Lots of single-use water bottles made from poly(ethylene terephthalate) (PET) end up in landfills, but there's a growing interest in upcycling them instead. Researchers in Energy & Fuels report on new heat-based fabrication methods to transform PET into supercapacitor electrodes and separator films for upcycled energy storage devices. In demonstrations, an all-plastic supercapacitor made from discarded water bottles outperformed a similar design that used a traditional glass fiber separator.
