yes yes, we can all calculate the power in H2 but. . . has anyone paid attention to history? what was the last device to use H2 on a large scale, can you say 'Hindenburg' H2 is a bit more volitale than gasoline. just what we need, a bunch of dumb drivers with a bomb of H2 on the back of their cars. a little fender bender punctures the tank. . . then you can say goodbye to like the entire block around the car (ok maybe not that bad) but all you making the calcultions, you must have had a chem class recently (or in your memory) and when i was in chem class, my proff always blew up hydrogen baloons. . . like little balloons would wake up everyone in a huge lecture hall. . . i couldnt imagine the effects of a larege pressurized tank surrounded by a car full of shrapnel. maybe everyone will become safer drivers. . . or at least all the non-safe drivers would be blown sky high. . . and thats not even considering the large tankers of H2 diving around filling up gas stations. . . or gas stations themselves. . . you get a hole in a gasoline tank and you clean up a bit and patch the hole. . . you get a hole in your h2 tank and well there will be people cleaning up and re-building for quite a while.
just a thought.
