WaveSpinner

Go to Danish version

WaveSpinner is a floatbased wave energy converter. The transmission system converts the up and down going movements of the float into a continued rotation of a couple of flywheels. A PM-generator vil be integrated in the flywheel system. A model in scale 1:20 has been tested in a wave tank at the University of Aalborg and at the test site in Nissum Bredning, Limfjord, Denmark.

  

The construction works. A video streamer shows HOW.
Patent registrered: DK BR 2006 00320

So far the machinery is made of ordinary bicycle parts in a frame of alloy .
Next step is to build a bigger prototype of non-corrosive materials. This is only one module. The idea is to combine many modules to a bigger wave power plant, WaveSpinners Connected.
