WaveRoller Uses Swinging Door for Underwater Wave Energy

One of the better ocean energy ideas as it is not a fish trap. It may take a few fishing lines though...

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.

Each 20 ton WaveRoller “door” can be connected together in threes to make up a nearly 1 MW unit. Obviously you can make a modular farm of any size under the ocean of these three-packed units, so the output can be as much as you can build tons-worth of “doors”.

Interesting. I'd like to see how this turns out.
