A totally new energy source in slow moving rivers
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: University of Michigan researchers spent years creating a water-harnessing river turbine to create electricity, called the VIVACE. It's the first time electricity appears to be effectively generated in slower rivers rather than oceans, but that's because the developers used physics to get turning turbines to agitate the water enough to create more energy for their neighboring cylinders. It's an as-yet prototype but a promising new development in the realm of water-powered electricity.

ICYMI: Sea power could take wind power's bragging rights
try{document.getElementById("aol-cms-player-1").style.display="none";}catch(e){}Today on In Case You Missed It: Nova Innovation is installing the world's first tidal power generators along the coast of Scotland, which are able to produce 100 kilowatts of power each. The UK Carbon Trust estimates the tidal energy market will be worth $165 Billion by 2050.

Researchers use graphene to draw energy from flowing water, self-powered micro-robots to follow?
What can't graphene do? The wonder material's been at the heart of a stunning number of technological breakthroughs of late, and now it's adding oil exploration to its long list of achievements. A team of researchers at Rensselaer Polytechnic Institute have discovered that the flow of good old H2O over a sheet of graphene can generate enough electricity to power "tiny sensors" used in tracking down oil deposits. The gang, led by professor Nikhil Koratkar, was able to suck 85 nanowatts of power out of a slab of graphene measuring .03 by .015 millimeters. The little sensors the researchers speak of are pumped into potential oil wells via a stream of water, and are then put to work sniffing out hydrocarbons indicative of hidden pockets of oil and natural gas. Of course, that doesn't have a whole lot of practical application for your average gadget consumer, but Koraktar sees a future filled with tiny water-powered robots and micro-submarines -- we can dig it.
Inhabitat's Week in Green: LAVA's geodesic home, solar skyscraper glass and fear of nuclear power
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 showcased several groundbreaking feats of high-tech architecture - starting with plans to transform the United States' tallest skyscraper into a soaring solar farm. We also saw a vision for a geodesic home of the future that is popping up in China this year, and we learned that scientists in Qatar are developing a series of solar-powered artificial clouds that will cool the country's stadiums during the 2022 World Cup. It was a big week for energy news as well as Germany and Italy announced plans to abandon nuclear power in the wake of the crisis in Japan. Tata & MIT also announced a breakthrough technology for generating power from water, and we saw solar energy reach new heights as Suntech set off to install the world's tallest solar plant on the Tibetan Plateau. Speaking of soaring green designs, we watched a brand new electric vehicle take to the skies as the solar-powered Elektra One airplane successfully completed its maiden flight. This week we also showcased several cutting-edge examples of wearable technology including an app that instantly transforms any drawing into a made-to-measure dress. We also learned that Virgin Atlantic now offers passengers bespoke shoes while they wait, and we took a look at a futuristic pregnancy belt that offers an inside look at the womb. Finally, we saw several amazing examples of recycled design - Chinese artist Wing Wah has created a set of scrap metal transformer robots that look just like the movies, and designer Mati Karmin has transformed defused land mines into an edgy set of interior furnishings.
H2O Shower Powered Radio blasts the Biebs by way of micro-turbine
Forget the tablet, 2011 is the year of the shower radio! Last week we reported on Toshiba's wirelessly connected water-proof song box and, just as our nerves began to settle from the excitement, someone came along and dropped this eco-friendly, shower-ready gem on us. Not only is the H2O Shower Powered Radio waterproof, but it actually uses the water from your shower to pump out the jams. The thing connects directly to your shower hose, and uses the flow of water to set a micro-turbine spinning, thus charging an integral battery and eliminating the need for disposables. As the video below points out, the radio "doesn't just offer 80s classics -- it has the full spectrum of FM," and its creators say it's compatible with 99 percent of showers, but what we really want to know is: how well does it crank the Ke$ha? Video after the break.
Samsung aiming for water-powered cellphones by 2010
We've seen quite a few prototype fuel-cell powered mobile devices, but Samsung's upping the ante by predicting that we'll all be running our phones on water by 2010. The company says it's developed a method to generate hydrogen by exposing water to metal, but the details are a little shaky -- we're guessing it's similar to the system used in the HydroPak generator, but it's hard to tell. Still, we've got no reason to doubt Samsung's engineers, who say the system currently provides about 10 hours of use, or about five days of average cell usage, and will eventually allow users to simply top off and go. That's every traveler's dream -- let's get this to market, Sammy.
Water-activated portable power generator on the horizon
We've seen our fair share of diminutive power generators, but rather than worrying with vibrations or hyperventilating, Millennium Cell and Horizon Fuel Cell have teamed up to deliver an iteration that's water-activated. The pair has been working together on this technology for some time now, and apparently, it's readying a beta that will be demonstrated at next year's CES. The portable power generator incorporates a "unique water-activated cartridge system," which is designed to quietly provide clean energy to consumer products in emergencies and when far, far away from an electrical outlet. Reportedly, the device will provide an AC socket alongside two USB connectors, an operating time of over 16-hours, infinite shelf-storage life and 400-watts of instant juice by just adding H2O. Regrettably, we still have no idea what this thing actually looks like, but considering that CES is less than two months away, we'll soon be seeing what this $400 gizmo can do up close and in person.
