This is great:
Now, a little engineering analysis, courtesy ME - philosopher / engineer in the classic tradition of Archimedes:
"Hydrogen combines with oxygen to produce electricity."
No it doesn't. Hydrogen combines with oxygen to produce HEAT and FLAME. This heat energy must somehow be converted to mechanical energy, to turn a generator to produce electricity - this task is typically accomplished by heating water into steam, to drive a turbine which in turn spins a generator, which is a big electric coil that produces electricity. Even nuclear power plants work this way.
The byproduct of the chemical reaction of hydrogen and oxygen is water - this is true. But where does the hydrogen come from?
Hydrogen exists in nature in the form of water - H2O, also known as 'dihydrogen monoxide' - DHMO. To extract the hydrogen from the water requires running an electric current through the water - a process known as 'electrolysis'.
So where does the electricity come from, to get the hydrogen to fuel the car?
Most electricity is produced by fossil fuel power plants. Most fossil fuel power plants burn coal; 80% of the electricity in North America is produced this way.
In other words, this hydrogen fuel cell car is no different than the electric car - the energy required to drive it is derived from good old-fashioned coal.
Ergo, to say that this car is pollution-free is like a man eating a steak saying he's a vegetarian by default, in that the cow he eats is a herbivore.
What I really want to know is how come all these "Car of the Future" cars always look like souped-up Prius's? EFF THAT. It's 2010 - when are we going to get THESE THINGS???
