Here's a tidbit on a hydrogen car I saw.
It was the early 60's in wealthy burbs north of Detroit. I was driving with Dad and he pointed it out "Oh there's ***, that car is powered by hydrogen". I don't recall ***'s name, but Dad said he was head of GM Tech.
Now the first thing I said was "Dad, that's guy's drivin a rolling bomb, he could take out the neighborhood!" Then Dad said, "oh it's a bomb alright, *** told me it has very impressive acceleration, as to being explosive, it doesn't store the hydrogen. I bumped into him at the Mobil station at Long Lake and Woodward where he was cleaning his windshield and had a look under the hood. Two thick walled pint nalgene canisters, one of hydogen peroxide the other of hydrochloic acid. (Dad explained which dripped into which, but I don't recall). So it goes from the second canister straight to the injectors". Guy was also bragging it went 3 months on one fill up.
Now I'm not a chemist, but having grown up in Detriot I can guarantee that if you develop something like this and don't sell it to one of the Big3 when they come calling (who will without doubt add it to a long list other fuel "saving" improvements lining their circular dead files), you will find yourself wearing some mighty heavy shoes and taking on water very rapidly.
So much for integrity in that town. btw, In searching the net high and low for any info on this 64' Tornado this interesting link came up.

(Dad explained which dripped into which, but I don't recall).Could conceivably power, maybe, a rather small amatuer liquid fueled rocket. There is only so much energy in any chemical fuel, and that energy is calculable. The amount of energy nescessary to move a given weight of machinery a given distance is also calculable. Even two pints of a very high energy fuel such as nitroglycerine would not power a car for three months. All of these "super carburetor" and magic fuel sclaims are so much BS.
