The issue isn't that it costs more to get Hydrogen from water than what you get for it.

What matters is that the overall process is cheaper than gasoline.

Today, nothing beats the amount of energy you walk around with in a gallon gas can.

Hydrogen must be pressurized to 10,000 psi to be able to carry enough energy to give a car any reasonable range.

And the GM "in your driveway" (another GM innovation they can't seem to get credit for) it takes far longer to fill hydrogen tanks than to put 12 gallons of gas in a car. However, this is likely more feasible than recharging a battery in just minutes. As my friend always said, "do you want you wife or kid arc welding around the car?" And this is from a guy working on hybrids.

I would be very interested to see what patents he released and what their real value is. Keeping mind his car is more innovative in styling than propulsion or energy storage. My guess is this more a marketing ploy than meaningful information. He is a master marketer and likely the stock went up because he did this making him personally even richer.

The company does not make money selling cars. It makes money selling ZEV credits. They did get a bunch of government loans, which no one seems to care about. But at building cars, not a dime as of yet.
