Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green.
This week Inhabitat saw geothermal power projects pick up steam around the world as Iceland eyed liquid magma as an energy source and the UK sought to tap geothermal reserves under Newcastle. We also saw scientists develop a stretchable solar-powered sensor that can detect the drop of a pin, and we were impressed by a brilliant system that uses algae to treat wastewater and generate fuel in one fell swoop.
We also showcased several innovative examples of high-tech architecture - Wales' futuristic newport transit station and a massive green-roofed innovation hub that is set to become Botswana's first LEED-certified building. Solar-powered structures were a hot topic as well as we took a look inside SunPower's incredible renovated headquarters, learned about the new location of the 2011 Solar Decathlon, and showcased a photovoltaic-powered alpine eco shelter.
Finally, this week we got set for the start of spring by sharing our five favorite green gadget gardening tools and a rainwater recycling system that comes complete with a solar pump. We also spotted a chic cradle-to-cradle raincoat that will fend off impending showers and a natty wool iPad cover that will keep your tablet cozy in blustery weather.
