Crazy Idea? Apparently not.

Years ago I had an idea that must have sounded crazy at the time. If we're looking for renewable energy, why don't we harness the energy we exert every day just by walking down the street? I figured some genius out there could design a system beneath the world's sidewalks that could channel the energy exerted from foot traffic to power grids all over the world.

Well, I don't know how I missed this, but apparently there are folks working on a very similar project right now. It's called the Pacesetter's Project and it's happening in the UK. You can read more about it here and here.
