I can't believe how unintelligent and ignorant people can be.
Hydrogen is a flammable gas, not a volatile one. Hydrogen burns pretty much like natural gas and can be stored pretty much similar to natural gas. It is safe for transportation using special tanks of high pressure variety or the absorbent low pressure variety or even liquid cryogenic method similar to CNG, ANG and LNG.
Perpetual machines do not exist and can not be built.
Hydrogen to water is what wood is to burnt ash. To say, a car or motorcycle runs on water is to say burnt ash is a good fuel to start huge fires. Yes, one comes from the other but it has been chemically changed (oxidized). To create hydrogen from water more energy is needed (through hydrolysis for example), than the burning of hydrogen can provide. Thus using energy to make hydrogen from water and using that hydrogen as an energy source is wasteful with current technologies.
so what you say to someone who studied business all his life, is a CEO of a major bank making 5 million a year, knows nothing about physics and if someone tells him a car can be run with water, he goes maybe you can...is he an ignorant and unintelligent person. What if he asks you how to do option trading and you go duh what is that and he says how can you be so ignorant and unintelligent everyone in the stock market knows about options trading. I think you get the point dont you?
