Do any of those systems generate power without using any fuel? Theo

Nah, a single-bar room heater in only 1 Kw. I gues you can check if that theory is correct by checking to see if there is any paint left on the underside of the bonnet. Theo

No. Thanks for trying to bluff that one. Remember the discussion re: torque...... GS mentioned speed as a way to suggest that the figures were in agreeance. Perhaps you missed that? Perhaps you missed the 12 v vs 24 v comment as well? > >> Also, we were talking about headlights.

Yeah, I mean, lets *not* consider efficiency.....

As I said, when I get home. I'm still 400 odd kays and coupla days from that. BTW, I looked at your numbers again, as well as your assumptions, can you tell me why you are getting the same consumption figure regardless of speed, regardless of engine rpm? > > big Hammo |
