The Denmark-based company are developing a process – called the Wavestar – that converts the energy from waves through floats on the surface of the ocean. The concept was invented by sailing enthusiasts Niels and Keld Hansen in 2000. The challenge was to create a regular output of energy from periodic ocean swells and waves that are 5-10 seconds apart . This was achieved by developing a floating machine with a row of half-submerged buoys, which rise and fall in turn as the wave passes. This rise and fall movement allows energy to be continually produced despite waves being periodic. Credit: Wavestar
