Australia's Prototype Wave Generators Move Like an Electrified Kelp…

The gentle swaying of kelp forests belies the immense hydraulic pressures they've evolved to endure. The waves that crash over them transfer huge amounts of energy—an average of 36kW/m with three-foot swells. Now, a green energy firm is banking on this sway to run arrays of Megawatt generators of the coast of Victoria. » 12/15/11 11:30am 12/15/11 11:30am

Here's Proof That People Have Been Trying to Go Green for Over a Century

When you think power generation in the early 1900s, coal and steam generally come to mind. But in Alexis Madrigal's upcoming book, Powering The Dream: The History and Promise of Green Technology, he shows that people were trying to find environmentally friendly alternatives via ocean waves in the nascent days of… » 4/08/11 11:40pm 4/08/11 11:40pm

Searaser Wave Buoy Can Generate, Store Enough Power For 470 Homes

We've mentioned ocean » 11/19/08 8:34am 11/19/08 8:34am stations a bit recently, and now here's one with a rather different approach: It can store power for when its needed. Searaser is in prototype form at the moment, and it works by bobbing up and down as waves pass by. An underwater pump uses this motion to push water into a reservoir 160 feet…

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

69 Year Old Attempts Record Hawaii to Japan Trip in Wave Powered Boat

Ken-ichi Horie, a 69 year old Japanese sailor, is planning a solo 4,350 mile trip from Hawaii to Japan using the most advanced wave powered boat on the planet. If successful, the trip would earn him a Guinness record while simultaneously proving the viability of wave powered propulsion. His boat, the Suntory Mermaid… » 2/22/08 8:50pm 2/22/08 8:50pm

Wave Farming for Power is Going Commercial in California

California's Pacific Gas & Electric has signed an agreement with Finavera Renewables to supply 2 megawatts of electricity that will be generated by a "wave farm" set 2.5 miles off the coast near Humboldt County. This move is expected to offset 245 tons of carbon dioxide annually. At the heart of the project will be… » 12/18/07 7:40pm 12/18/07 7:40pm
