I saw a comparison between hydrogen and gas powered vehicles. With hydrogen, the gas goes up and burns. With gas, it splashes on every thing and burns.
I read that they had developed a safe way to store the hydrogen and it would not leak or explode even if it was dented. It was a documentary on electric vehicles.
"British steampunks have successfully tested a steam-powered car they want to see race across the California desert at 170 mph. They aim to break a record that has stood for more than a century".
There is no free lunch. It takes energy to separate the hydrogen from oxygen in water. Look at the label on a bottle of water, it has no calories. No calories means no energy. I would guess that either this is a complete scam, or that the "energy generator" needs to be recharged frequently and expensively.
...good one Karl..good one..
..since you put it so delicately... let me tip toe through the land mines and ask..
...regular or premium?...leaded or unleaded?..
Actually, Bob, the energy to break a bond is the same as when you combine them under the right circumstances. But the major point is you cannot extract *more* energy. It's the reciprocity (splitting/combining are same energy) that help make hydrogen a superb energy storage device for fuel cells! (But not so much for internal combustion).
Like with all systems, there is some practical loss - friction, resistance, heat, light - that makes it so it's not a perpetual motion machine. Similar principles are behind why you can't use a generator to provide enough electricity to run a motor to power the generator and - viola! - free electricity. No.
I should have clarified and used the term, "Usable Energy".
So yes, E(in) = E(out), but as you pointed out, there's there are several losses that we can't recover the energy from...
But most of the energy can be recovered from electrolysis generation of hydrogen and fuel cell consumption to turn hydrogen and oxygen directly to electricity without combustion.
As pointed out above, there is the equivalent of about 17,500 calories in a pint of gasoline. Calories are measured by the amount of heat (energy) given off when the subject is burned.

the potential heat you can generate by burning gasoline depends on too many variables; the octane, for one...as well as the fuel/oxygen mixture, etc.
... a calorie is the amount of energy, or heat, it takes to raise the temperature of 1 gram of water 1 degree Celsius (1.8 degrees Fahrenheit)...
...A gallon of gasoline contains 31,000 kilocalories or 31,000,000 calories...but who's counting..
