The energy to spin a generator (and alternators) is horsepower. If generators produced electricity without any effort, we could have tiny steam engines turning the powerstation's big generators. The electricity is made by draging magnetic lines of force through a coil of wire. This takes mechanical energy. That comes from the shaft going in, that trys to slow the shaft, that slows (your) wheel. What if there were dragging brakes on the trailer you discussed in your remarks above! Would your milage remain the same? No it would be reduced by the amount of (heat) energy being wasted. The same applies to the generator hooked to the fifth wheel. It drags on the axle, taking power from the pull vehicle. All of the methods of making electricity (or any source of power) comes from the conversion of other sources. An alternator of high efficiency might make 60% of its output in electricity and the remainder in heat and bearing friction (heat). Wild, I hope this explains why people are reacting to your idea in the way they are. with respect, Jim

The first fleet arrived in 1788 and consisted mainly of convicts who were poorly equipped and new little of farming techniques. The colony remained far from self-supporting and it was not until the early 1800's that things started to improve. Free settlers started to arrive, they followed the explorers across the mountains and where land was suitable set up farms. T
