Sea 'snake' generates electricity with every wave

Anaconda, a giant rubber “snake” that floats offshore and converts wave energy to electricity, is a step closer to commercialisation. An 8-metre long, 1/25th scale version is currently undergoing tests in a large wave tank in Gosport, UK, and a full-size working version could be a reality in five years.

…The tube is anchored at one end and as waves wash along its length they exert pressure on the snake that is transmitted by the water inside. This forces Anaconda’s walls to expand outwards into the wave troughs where they are under less pressure, forming “bulge waves” that travel along the Anaconda’s length.

…When each bulge wave reaches the end of the snake it keeps a turbine spinning to generate electricity.

The snake is made from a rubber-based material similar to that used to make dracones
