WaveRoller Uses Swinging Door for Underwater Wave Energy

The simplest ideas are best at harnessing underwater wave energy. You don’t want lots of parts in the harsh marine environment (for machine parts) under the ocean. Here’s an idea from a diver from Finland who was almost hit in the head by a shipwreck door that inspired this invention: the WaveRoller.
Now the EU is funding the diver; Rauno Koivusaari, with $4.4 million for his company AW-Energy to build the first full scale demo of his invention.
Each one at full size weighs 20 tons and produces 300 KW.
