Yep, that was a liquid oxygen stir that caused the problem. You would have different issues with a land-based fuel cell.
that joke is a little too overused.
you forgot to include unicorn farts....LOL But you're right. Hydrogen may have possibilities, but it is not going to be free. The energy to convert it from other compounds has to come from somewhere (fossil fuels or nuclear). The percentage of free hydrogen in the atmosphere is 0.000055% so that is not exactly a legitimate source
I prefer a clue
x 4 with the rusty nail modification for such beatings.
Bingo! When the government regulates the most plentiful element, we will have a shortage.
Its simple enough to separate hydrogen from oxygen in water and its a common 6th grade science experiment. The problem for cars is that it takes a lot of energy to do it at the rates a car would need it on demand.
If hydrogen is called a fuel, why can't electricity also be thought of as a fuel? Seems a subtle concept but it's key to avoid falling into the trap of trying to violate the Second Law of Thermodynamics.
Engineers know that to get hydrogen it takes more energy to recover it from a compound than the energy obtained from recombining it with oxygen. Unlike carbon-stabilized hydrogen in fossil fuels, hydrogen is not found floating around in the free state.
Simple answer: Hydrogen (H) is an element, and H2 and hydrocarbons are molecules; electricity is neither.
Further, a battery carries electricy to power a system thereby behaving as a fuel source.
No, batteries act as an energy source for an electrical system. Fuel cells require the oxidation of a fuel source (hydrogen or hydrocarbons) to generate electricity.
Yes, I am familiar with the issues of extracting and storing hydrogen.
Carbon monoxide has almost the same energy density as hydrogen, so were is the fuss about the dangers of carbon monoxide ?
Yes, carbon monoxide is also a combustible.
Humans produce hydrogen as a digestion byproduct every day.
Hydrogen is actually safer in a vehicle than gasoline or LNG, or propane since hydrogen disapates much faster than all of those other fules and does not cling or rather stay on the ground pooling.
There is much hype about what happen to the Hindenburg which is not true.
It was the very flamable paints that they used on the out side of the Hindenburg that caused the initial flames.

“Non-engineers know that hydrogen is the way to go.”
Because public schools have been turnng out total idiots for 40+ years!!!
Bump!
Hating other inhabitants of this planet is a very costly passion.
I agree. Hydrogen has its place. Fossil fuels, however, are so energy-dense and so much more readily available in consumable form that hydrogen cannot take their place.
Most people think that when they think of hydrogen production they think of electrolists.
However ? There is a much easier way and cheaper way to produce hydrogen from steam in a process called Gasification.
Check out a website called All Power Labs.
Much of the infrastructure for the production of hydrogen can be created from gascifiers and biomass.
A electric generator, or Internal Combustion Engines can be ran off of a gasifier.
During WWII most of the Scandinavian countries used gascifiers to run their cars, trucks, busses.
Yep. Energy density is the key. That is the reason that alternate energy sources will have a hard time displacing the internal combustion engine.
