Why can't electricity be generated by the spinning wheels of a car when it is driving normally? |
Why is it that engineers can't simply bolt on the required magnets to the wheels of a car to generate an alternating current as they spin? Why are we being told that it can only be generated when the car brakes. There must be a way to hook a car to a battery in such a way that once it has started rolling it can generate all the required energy using step-up transformers and gears or some such invention. Kind of like a bike's dynamo but in big. Store the surplus when it exists for when the car needs it. If mobile phone batteries have come so far along,we must be close. Size might be the problem, but perhaps someone could put down some numbers for me. Average car with a family of 4, driving at regular speed limits, etc. (Apologies to the community, my scientific mind just went off to order a cup of coffee or something stronger and left me with my question in my mouth and I've got my generator in a twist. I'm sure someone will kindly settle the workings of an AC/DC generator below The magnets would create more resistance then energy, thats how everything is, thats why perpetual motion with out soler energy is not possible. And its being done on the Hybrids like someone else said, but thats only when they are breaking it charges the batteries. Hope this helps. Already being done on some of the higher end hybrids. The downsized the technology from its railroad use as 'dynamic braking'. It works 'ok', but not the way in which _I_ would like. because the iron core, when generating power behaves like a magnet... and everything slows down... its called resistance. you cant get power for nothing. believe me, weve all tried and failed miserably.. nuclear fusion is as close as we can get, and thats a loda of hooey... as proven.. nuclear fission works... I'm nowhere near an expert on the subject, but don't cars already have alternators?? simply applying magnets would not work because a field must be placed around the magnets to make it work. My proposal is install a field around drive shaft or axles to generate power The additional work required would be greater than the energy generated. If not you would have a perpetual motion machine. There are cars that get energy from the braking system. good ??..But does it only when braking?Because of the size of batterys im sure you can make much more elect than u can store .as for phone batterys all they do is move electrons which dont weigh as much as a 3,000 lb car. |
