Hydrogen has 60,000 btu per pound. Gasoline around 23,000. So right off the bat, yes, you get better fuel economy. The cool torch would be normal. If the flame was as hot at the torch head as at the stuff you want to melt, the torch would melt first.
Bottom line, it still takes more energy than you yield to disassociate water and then burn it.
It's Fox News. The laws of physics don't matter to them.
On edit: They are right about one thing. Acetylene goes unstable at around 3psi.

3. LOL FOX NEWS - the no physics zone |

"it still takes more energy than you yield to disassociate water and then burn it." that is correct, but, if you can keep adding small amounts of electricity generated by solar power or a gasoline driven alternator/generator or both, could keep the vehicle running. that is why I think that they had to make the escort wagon run on BOTH gas and water, you must run the engine on gasoline for a certain amount of time to generate the electricity needed to continue to generate hydrogen.
I'm still skeptical, as you are, but we MUST honestly explore all avenues of alternative power and fuel so we can give the finger to the middle eastern oil sheiks.

4. More fun facts about hydrogen |
|
Edited on Sun May-21-06 09:25 AM by Turbineguy
Hydrogen has a higher tensile strength than steel and hydrogen embrittlement is a problem. Simply speaking, hydrogen fuel systems would require special metals, likely radiologic QA during manufacturing, extra and specialized maintenance requirements. But on the other hand, hydrogen car accidents would give spectacular explosions and this of course would be of value to Fox News.

5. There are no hydrogen wells. |

It's not something that can be pumped ready-to-use out of the ground. Hydrogen must be made by one process or another, and in the process of making hydrogen you are actually storing energy. But you will never get as much energy back out of the hydrogen as you put into the job of producing it. Hydrogen is a "chemical battery" that has to be re-charged, and is a net energy loser. There will never be a "hydrogen economy" because hydrogen is not, and never will be a SOURCE of energy. It will never be more than a way to STORE energy, and that energy has to come from some other source.
