Hydrogen, unlike gasoline, does NOT behave well at room temperature. There is no way, EVER, that we should use hydrogen as a fuel in consumer vehicles. The result of hydrogen use is predictable.
In several sci fi rpg’s I’ve played, the fuel for a reactor was a tank of water.
I think it’s worth it to use hydrogen when the independently measured energy density of the latest LENR device was 10,000X of gasoline.
Nope.....wrong. Hydrogen gas is used daily in tens (if not hundreds) of thousands of places, from cc/min to tons/min quantities, quite safely. The techniques of handling it safely are well developed and available off-the-shelf. Gasoline, when first used as a vehicular fuel, was perceived in much the same terms. Yet today, people use it in their cars, routinely, with minimal problems.
