In case this is a serious post, please Google "2nd law, thermodyniamics", and "hydrogen", "water"... all shall be explained. :P

This one ranks right up there with air-powered cars. There always seems to be small detail about thermodynamics that they fail to mention in the write-up.

i read about those air powered cars... when i first heard about them the first thing that came to mind- hmm... must be impact wrench technology... and essentially it is, just a little more efficient design

air power and energy

Post by franz » Sun Dec 03, 2006 9:27 pm

I read a scientific proposal about an air powered car that ran on a compressed air stored at 5,000 psig. They claimed that the compressed air would provide enough power to transport the car almost 130 miles and would be recharged during coasting down hills and when braking. What they neglected to mention is that it requires just about 4 times the amount of energy to compress the air than the compressed provides in kilowatts of real power. This is way upside down!

The last time I compress Natural Gas to 5,000 psig, it took over-night with a modified PHILL compressor (about the equivalent of a moderate sized CNG cylinder with about 6 equiv gallons of fuel). I seem to remember the last 4 hours only increased the pressure about 400 psig and the tank was pretty warm from compression.
