> Robert Shepherd at Cornell University in New York and his colleagues have turned instead methane, a chemical fuel that can store energy at a much higher density than lithium-ion batteries I think they're on to something there. Imagine a larger-scale vehicle driven using this internal combustion mechanism, large enough even to carry people. It would have a much bigger range than common electric vehicles. I'm pretty sure it will even be possible to use liquefied methane or one of its larger-chained family members which would negate the use of pressure vessels to carry methane and make for a quick and easy recharge, especially compared with the batteries we're used to. I'm off to the patent office, this invention will change the world.
