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.
South Carolina-based Firefly Power is one of 20 other social- or environmentally-inclined companies presenting at the i2i Awards program in conjunction with SXSW Eco in Austin through Friday, October 5, 2012. The company makes lightweight small wind turbines out of carbon-fiber blades in the vertical axis form. The residential unit is rated at 1.8 kW, weighs less than 60 pounds, cuts in at 10 mph winds, and is expected to sell for about $7,000, according to Firefly Power.
Turns out the Rhône Alpes team from France with the Canopea house won Solar Decathlon Europe held in Madrid. Their home is actually the top of a conceptual “Nanotower” that the team proposed to bring single-family style living back to the urban core. The top level acts like a rain forest’s canopy — hence the name — by collecting 95% of all solar energy and 30% of rainwater for the tower. Canopea was built of a prefab CORE, site-built SKIN, and a SHELL capable of off-site fabrication as well.
