HHOgas I think you should take the advice of many previous posters and clear off, no-one takes you seriously here when we all know that the round trip efficiency for hydrogen to useful power is south of 50%. Hydrogen may yet have a place in the future of world energy but it has huge economic and practical headwinds to overcome first.
I take it you don't use any of the huge range of cordless power tools for workshop and garden, laptop computers, mobile phones in their many different forms, most drones or other remote control vehicles, decent quality solar lights, rechargeable torch or any device that relies on the power density of modern Lithium chemistry batteries because they might explode into flames. Well they might but your ICE vehicle would be far more likely to hurt you than any Lithium battery unless you deliberately abuse it.
