A UK engineer has invented a device that harnesses wave power to pump sea water uphill, from where it can flow downhill to create hydroelectricity, raising hopes of a cheap, abundant source of renewable energy.
In trials, the device, called the Searaser, has pumped water more than 160ft above sea level, using little more than the natural motion of the waves. There are now plans for a much larger version, capable of pumping to a height of more than 650ft.
Inventor Alvin Smith reckons that each full-size device would be able to pump enough water to supply electricity to 470 homes. He also calculates that a fleet of 43,000 could generate enough power for a staggering 20 million households.

The phone went the other day. Nice chap at the other end – a press contact. And he thanked me for the coverage I’d given this story in the past. Very rare in this game.
It turns out that Lyme Bay – just an hour’s drive from here has had the victory we’d all hoped for.
One of the UK’s finest marine wildlife sites is set to be protected from damaging scallop-dredging, thanks to the introduction of a 60sq mile exclusion zone.
Paul Gompertz, Devon Wildlife Trust’s director, said: “This is one small step for marine but one giant leap for marine-kind. It finally acknowledges that our seas need vital life-support systems like Lyme Bay reefs.
“It’s taken 18 years, hundreds of thousands of fundraised pounds, the energy and dedication of many people - and a host of setbacks and heartache along the way. But it has all been worth it - to see a new day dawn for the future of marine conservation in this country. The Government is to be congratulated on a bold step. Now we need to see the exclusions enforced.”
