Using the ocean to generate power is an old idea, but one that so far hasn’t spat out its ‘killer app’. Until now, perhaps – enter biomimetic ocean power. These are devices designed to react to ocean waves in the most effective and efficient way possible, by mimicking the form and motion of things that belong in that environment, like kelp and fish tails. Seriously – it sounds a little leftfield at first, but it looks like they’ve really thought this through.
