Ocean Power Delivery

OPD, Ocean Power Delivery, creates an amazing system for generating up to 750 kilowatts of electricty from the movement of offshore waves. Renewable energy is a huge topic into our near future and OPD is one very unique option to follow. I wonder if theres a system to renew energy through roads, highways, or the freakin shaking floors in malls when you just stand still. Perhaps malls will one day be partially powered by the traffic they get.
