ICYMI: Hand over your car to the robot overlords
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: A new parking structure will autonomously park cars without a single human's assistance. Meanwhile Colorado School of Mines is testing small-scale water treatment plants that could be used in neighborhoods rather than one city location. And Canadians sent the US a darling little 'keep your head up' video that has us saying aww! The machine mating video on YouTube can be found here. As always, please share any interesting tech or science videos you find by using the #ICYMI hashtag on Twitter for @mskerryd.
Researchers create super-efficient microbial fuel cell, dream of selling excess electricity
Recycling wastewater to generate energy has turned up noses before, but researchers at Oregon State University have developed a microbial fuel cell that can create 10 to 50, or even 100 times more electricity per volume than similar technologies. After refining the tech for several years using new materials, techniques and selecting better microbes, the team can now extract two kilowatts per cubic meter of refuse. As bacteria oxidizes organic matter, electrons -- rather than the hydrogen or methane that other methods rely upon -- are produced and run from an anode to a cathode within the device to create an electric current. Once implementation costs are cut down, the technology could power waste treatment plants and enable them to sell excess electricity. The contraption isn't just for processing what comes out of the porcelain throne -- it can also utilize materials ranging from grass straw to beer brewing byproducts. For now, however, the cell will tackle a pilot study before it inches closer to your local brewery or water treatment facility.
Inhabitat's Week in Green: SunPower supplants Ford, lava power, and the airlifted eco shelter
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.
New York City turns to sewers for energy solutions
Listen up New Yorkers, those hot nuts you just swallowed could be used to light the signs on Broadway. Okay, so that's a stretch, but the city's Department of Environmental Protection (DEP) just issued a plan to turn the stuff you flush, along with rest of its wastewater, into renewable energy. New York City produces about 1.3 billion gallons of wastewater daily, yielding 1,200 tons of biosolids that can be harvested to procure methane -- already accounting for 20 percent of the city's energy -- and butanol, a clean gasoline alternative. The plan, which also includes wind and solar projects, aims to use gas, converted by large digesters, to "power wastewater operations, meet on-site heat and electricity needs, and, where feasible, sell excess energy to the market." As the DEP points out, the plan isn't far fetched -- we've seen a couple of solutions for turning human excrement into usable energy, and a project already under way in Greenpoint is estimated to procure enough methane over the next year to heat 2,500 homes. Now, if that doesn't give you a newfound respect for the porcelain throne, we don't know what will.
