Free of charge sustainable energy, what a dream that would be. Everyone’s tried to do it, but nobody has ever cracked. From cars that run on water or vegetable oil to imaginative geometrically designed perpetual motion contraptions, it’s one of the last great quests of inventors everywhere. To actually come up with something that can give us a free, everlasting source of power that doesn’t destroy the environment and is cheap to produce and share.
People have been trying for centuries to do it, yet we are still far far far far off from ever reaching this point. Until then though, what we can do is reduce costs. Slash our spending right in half by seeking out the best deals for us with theEnergy comparison sites and other familiar interwebby generations. The future might still be a long way off but we need not be out of pocket for it.
