London, Nov 17 : Researchers have developed a device that harnesses the power of the sea to push water uphill to provide cheap renewable electricity.
According to a report in The Times, the invention, known as ‘Searaser’, is designed to pump water hundreds of feet above sea level from where it can gush downhill to drive hydroelectric generators.
Pumping is made possible by the motion of waves lifting the device, as it floats in the sea, and gravity bringing it down again in the wave troughs.
