This has been all over the 'net in the past few days. The last car that actually "ran" on water was the Stanley Steamer, and even there the water was converted to steam by an external energy source.

Water isn't a fuel. Hydrogen (in all its various combinations) is an energy storage medium that carries energy put into it from another source. I don't get a clear read on what that source is and what how efficient of a conversion is going on.

The theory has been around for decades, in fact I understand that the Brits used the process during WWII to power buses. They had coal to produce the electricity needed for the hydrogen making but not enough oil to run the buses, so although it was a net lose they still could run their mass transit system long enough to beat the Axis and start getting oil again.

The problem is that it is far from efficient. You simply cannot get more power out of something than what is put into it in some form or another and in this cast the electricity used to convert the water exceeds the energy held in the resulting hydrogen.

The idea has been hawked for the past few years by some guy appearing on Saturday talk radio shows. It CAN work if you have no other alternative to produce a form of energy that you can use with the hardware on hand, see the Brit example above, but it is a net lose from an energy standpoint. The towel heads win again!

Although not technically considered a "fuel" water does contain vast amounts of energy, more so than gasoline.

Proof: E=MC2

The inherent energy in any substance is directly related to its mass. Water, being heavier than gasoline, contains more energy (proportionate to its additional mass for the same volume).

As others have stated, the key is the conversion from mass to energy which right now is done by electrolosis and is quite ineffiecient and then the hydrogen is burned, also inefficient.

Now some fun facts:
one pound of water contains the same amount of energy (if converted 100% effiecently) as 9 billion kilowatt hours or burning 5 1/2 million barrels of oil.

Now if I could just figure out how to....

Seriously, I know some of you will doubt, but the numbers don't lie, and if prompted, I'll bore you with them.
