Manchester University is testing a wave energy device that uses the “bobbing” effect of water to produce more power than offshore windfarms.

The waves produce an oscillatory motion that is converted into one-directional motion through a clutch, which drives the generator. If the system is put into full-scale use the Bobber units will be attached to a platform or rig with the mechanics and generator on top. Mounting the units on decommissioned offshore oil-rigs is also being explored by the team.

Professor Peter Stansby, co-inventor of the Bobber, said: “When you hear that a wind turbine produces 2MW, that actually indicates the maximum output. The Bobber’s output of 5MW is the mean power output, with the potential for much more depending on sea conditions.”
