Subject: RE:Hydrogen again by Slalom4me on 2008/2/12 18:19:52 Quote: At this time, I do not have a sense of the volume of water that would be (Slalom4me produces a paper napkin) One thousand Watts (1 kW) is roughly equivalent to 1.34 horsepower. Arbitrarily suppose that a 2,400 lb vehicle requires 20 road horse power to travel at 30 MPH. Arbitrarily suppose 15% drivetrain losses, thus 20 RHP becomes 23.5 motor HP. 23.5 MHP / 1.34 HP per kW = 17.54 kW So, is 17.54 kW or 17,540 Watts at a 30 MPH cruise reasonable for a small efficient car? In the earlier post I wrote that it seems the Toshiba stationary FC expels 53 gal while producing 700 W. There has to be something wrong with the information or the reasoning. I can't imagine that an FC-equipped vehicle is going to be expelling 1,330 gals of water while producing 23.5 HP/hr. . |
