other tech: Electricity from waves and motion
Electricity generated from waves and motion by using low friction ferrofluid. Ferrofluid over a magnet is 40 times slippier than ice. Jeffrey Cheung of Rockwell Scientific in Los Angeles has generated at least 0.3 watts from a ocean buoy even in very calm waters. One hope is that in three years this could be scaled up to generate megawatts from the ocean current.
