Tell someone that you’ve invented a car that runs on water and they're liable to report you for fraud. That hasn’t stopped scientists and engineers at the U.S. Naval Research Laboratory (NSL) who want to run warships on seawater – or at least, to turn seawater into jet fuel. This may sound like they’ve been standing too close to the ether again, but the idea is to extract carbon dioxide and hydrogen from seawater and then convert these into jet fuel by a gas-to-liquids process. If this proves practical, American naval vessels could refuel themselves at sea.
