But of course if you actually wish to drive the car, you will need to provide more fuel than normal to acheive the same motivation results as you did before putting more load on the system and engine. -- Dale Porter GPX250 -> CBR600 -> VTR1000 + VT250F-J
From: Dale Porter on 7 Feb 2007 00:25 Think of it another way. Say you're on a health kick (YR!) and you're peddling away on an excercise bike. You have it set at a fairly low friction setting and are just peddling slowly. To peddle faster you apply more energy through your legs. However, increase the load via the friction setting and you need to use more energy to maintain the same speed. -- Dale Porter GPX250 -> CBR600 -> VTR1000 + VT250F-J

Er, no. The statement was that lights waste fuel. I have yet to see that it does. Hammo (...blinded by the obvious?) |
