First Stage Testing of Searaser Completed

Full-scale in-ocean Prototype Planned in the Next 12 Months

Dale Vince, OBE., started his green energy company, Ecotricity, way back in 1996 and has introduced green gas and many other clean energy innovations. His Searaser, invented by Alvin Smith and manufactured by Ecotricity, solves the cost and variable output problems faced by those who wish togain the power of the ocean.

It simply converts thewave's swell into a vertical push in a turbine onshore. A vertical piston moves up and down as a surface buoy and a seabed anchor and hose-raising buoy respond to wave movement. The piston pumps the pressured water to the turbine and electricity is created.

Many previous inventions have used an offshore assembly which is subject to corrosion and abrasion. Manufacture is therefore expensive and maintenance is very difficult in bad weather. With few moving parts, this system should last much longer and it can also be extended. The pumped water from a depth of 25m fills a coastal reservoir and this can perpetually supply a hydroelectric turbine. That solves the problem of variable output.
