Renewable Energy

I guess the only thing holding the US back from taking advantage of an unlimited supply of renewable energy are the political lobbyists in Washington. Oil and auto companies are rich right now, and they have a firm hold on our politicians. I was thinking about underwater wheels that take advantage of ocean currents as a source of energy. I thought it might be a new idea, but apparently it's been done since the 1700's. The NEW way to harness power from the ocean is brilliant. They have these things called wavefarms. Basically a wavefarm consists of giant flexible tubes that take the kenetic energy from the waves and convert it into electricity. 472 square miles of ocean could power the entire United Kingdom! That's amazing. Mix these ocean powers with solar power and we can change to a world that uses mainly renewable energy sources instead of fossil fuels. We need to do some research and find a way to invest in whoever has the patent.
