Here’s an update to an old article about a tree-shaped charger powered by solar energy. Vivien Muller’s Electree+ is on Kickstarter seeking to raise $200,000 to mass-produce these little home/office gadgets here in the USA. The new prototype will be made with an 14,000 mAh internal battery, 27 amorphous silicon solar cells (each about 3.7 inches), and an easy-to-assemble tree structure that can be customized. In case you’re interested, the early bird gets in at the ground level for ~$199.00.
When you’re generating a surplus of energy — similar to these solar-powered homeowners — having a sporty electrical vehicle seems to make sense. EVs and plug-in hybrids are becoming more popular, and I’ve seen all sorts of garage products for charging them. Perhaps one of the more interesting models of late is this EVSE-RS Plug-in charging station by AeroVironment. The portable, DIY charger just needs a dedicated 240-volt service and the station can be mounted and installed in a pinch.
This is a floating home that is entirely self-sufficient and docked in Maastricht, Netherlands. Designed by Pieter Kromwijk and referred to as Autarkhome, the solar-powered project was built to the Passivhaus standard and is 10 times more energy efficient than the average dwelling of similar size.
