This may be a bit off topic, but I have a question for you to consider: why has pneumatic motors for cars been suppressed for nearly a century now, when it beats the pants off hydrogen or eclectic cars? This is just pressurized air driven motors, which is not a new tech at all. They now make 5k PSI tanks with carbon fiber for better safety that can provide a 200 mile range per fill, has no pollution, or risk of a violent fiery explosion if in a serious collision, and far less hazardous land fill issues than old batteries, as well as a fraction of the weight of the energy source and motor. No expensive processing of the fuel, which can be set up at any fueling station for a fraction of the cost to recharge a tank in just a few minutes.
