There is no way in hell they were shoving the QUANTITY of hydrogen you seem to say it would require to do this??? There is no way in hell that tank was holding even a FRACTION of 3000 uncompressed gallons. if your math is right they would have had to empty that WHOLE TANK in 5 seconds or so to run that car for 5 seconds. they ran it longer than that and did NOT use very much gas or pressure to do so. a few gallons of gas AT MOST.
ie the math your displaying is in contradiction to what has been observed. One of them has to be off. big time.
How are these BTU numbers being generated? is the BTU's in gasoline the MOLECULAR energy potential of gasoline IE 100% matter conversion to energy or just the amount of energy we actually manage to get out of it for useful work?
and 15cents a KW ? where the hell do you live Hawaii? (seriously thats REALLY high) even our COMMERCIAL PROPERTY only pays 13.6 cents a kilowatt. we pay a lot less at home. (that 13.6cents is FULL BILL divided by kw's used ie including all generation transport etc.. fees)

My BTU data comes from the "Golf Research and Development Company" and the CONVERT TOTAL FUELS USED AND MILEAGE TO MPGe
spreadsheet from the Progressive Automotive X prize calculator.
The car you watch run was it on MythBusters? If so that was a K tank with around 1 lb of liquid hydrogen.
It takes very little fuel to run any engine at a idle. My car uses around 0.08 lbs/min of gasoline at idle.
My KW is 13 cents(I just check on line to see what were paying). The 15 cents was just used as an example. But even at 13 cents you can still see that its a losing proposition.
