Yea, I agree. But what about the FACT that it's so much denser of an energy source than any battery we have? The straight up truth is that right now, unless there is so amazing innovation, we are going to use every drop. In the short term at least the world's militaries will burn as much oil as they can. Regardless of what you hear in press releases, major industry, military, aerospace will not move from oil until there is a performance reason, not ethical not cost reason to do so.
