World's First Tidal Turbine Power Station Goes Online, Doesn't Blend…

However exciting the rubber robot snake wave power generator sounds, a real seagoing power station is way more interesting. And over in the UK, they've just turned on the world's first commercial tidal power generator station. SeaGen is situated in Strangford Lough, Northern Ireland, and it has twin turbines that spin… » 7/21/08 7:09am 7/21/08 7:09am

Huge Rubber Snake is No Joke, Generates Power From Waves

For some reason or other, we've shown you a lot of robotic snakes here on Giz. But this new one is kind of a robot snake in reverse: it's designed to float just beneath the surface of the sea and capture wave energy, which it then turns into electrical power. A science team in the UK has been working on the design,… » 7/06/08 11:00am 7/06/08 11:00am

Japan to Build Huge Solar Power Plants to Power Sharp Factories

The city of Sakai in Japan is going to have a glittering new "green" addition in 2010, when Sharp and Kansai Electric Power build two massive solar-electric power plants there. In a bid to make Sharp's factories more eco-friendly, the two plants will generate 10 megawatts and 28 megawatts of electricity and reduce CO2… » 6/25/08 5:10am 6/25/08 5:10am

AeroCam Turbine First to be Blowin' in the Wind for Under $1 Per Watt

The "$1 per Watt" barrier may not sound as impressive as the sound barrier, but this next-gen wind turbine is the first, and has an unusual design. The AeroCam's horizontal-axis, flat-blade shape has blades that're dynamically angled to maximize wind-catching. It's also compact, so can fit into urban environments, and… » 6/20/08 4:31am 6/20/08 4:31am

MIT Scientists Increase Fuel Cell Efficiency 50%

Scientists at MIT have been tackling the efficiency of next-gen power source fuel cells, and have discovered how to significantly improve it. Most current direct-methanol fuel cells use a membrane called Nafion sandwiched between their electrodes, and apparently it's got a flaw. As well as letting hydrogen nucleii… » 5/20/08 7:17am 5/20/08 7:17am

IBM Boosts Solar Cell Efficiency Using Magnifying Trick

IBM's researchers have been busily beavering away trying to improve solar power technology, and they've just come up with a neat solution that uses a surprisingly simple technique: concentrator photovoltaics. In much the same way as kids use magnifying glasses to focus the sun on things to burn them (we all did that,… » 5/16/08 10:15am 5/16/08 10:15am

Scientist's New Solar Panel Tech: Paint Your Home For Power

Forget old-news solar-power shingles: a team from Swansea in the UK have found a way of creating solar "panel" paint. A by-product of their research into degrading paint on steel surfaces, their invention is applied in layers to steel cladding, and converts a gentle 5% of inbound solar energy to electricity. Sounds… » 3/27/08 9:27am 3/27/08 9:27am

Nanowires Could Turn Your T-Shirts Into Nano-Power Stations

A nanotech invention by a US research team offers an intriguing glimpse of the future: slip on some nanowire-embedded clothes, plug your MP3 player or cellphone into them, and as you dance or walk around, your outfit generates enough power to run the gadget. More details on how the fabric works, and some nano-imagery… » 2/14/08 8:54am 2/14/08 8:54am
