Guest SouthGaZX Posted February 12, 2006 Share Posted February 12, 2006 i had been thinking about ways to make cars that run on electricity run longer without having to recharge or whatever (this relates to a z only if you ever thought about putting one of those electric engines in your car) but... wouldnt it be neat if you could find a way to make your rim's spinning motion actually charge the batteries? find a way to turn it into a sort of alternator... it would be crazy... and electric cars would basically always stay charged as long as you didnt just idle without moving for long periods of time.. but then maybe it could have an option when the battery gets too low swap over to gas until the car gets moving again.. i thought about this when i saw people with the spinner rims... i was like hey.. thats kind of like a windmill... wonder if you could use that to make electricity... then i thought well... if that would work why not a rim that didnt have spinners.. well... anyway... thats just a thought i had... sounds crazy.. but could it work??

TheNeedForZ Posted February 12, 2006 Share Posted February 12, 2006 ...and electric cars would basically always stay charged as long as you didnt just idle without moving... When you convert whatever spinning motion into whatever form of energy, the spinning energy is lost. In a purely electrical car, your concept will make the battery last longer but it will not always stay fully charged. Toyota Prius has no problem with idling at all, it simply shuts off when you are not moving. It recharges energy during braking and when going downhill.

deja Posted February 12, 2006 Share Posted February 12, 2006 but it goes against the basic law of physics "energy can not be created or destroyed, it can only be altered'> And that alteration always has a lose. Like TheNeedForZ said, it would help, but you can't produce the perpetual motion machine. A friend of mine made one of these way make in the '70s, it sort of worked but had a lot of bugs.

Dan Juday Posted February 12, 2006 Share Posted February 12, 2006 but it goes against the basic law of physics "energy can not be created or destroyed, it can only be altered'> And that alteration always has a lose.[/size'] Do you mean "loss"? If so, that's not true. In fact it contradicts what you quoted. Most of what we think is loss is really converted into heat. Quote Link to comment Share on other sites More sharing options...
deja Posted February 12, 2006 Share Posted February 12, 2006 Excuse me for the spelling error and phrasing that wrong, but the end result is the same. Quote Link to comment Share on other sites More sharing options...
AK-Z Posted February 12, 2006 Share Posted February 12, 2006 Some of the energy can be lost unintensionally in this case can be noise, vibrations, heat, and resistence. Quote Link to comment Share on other sites More sharing options...
Lewis Maudlin Posted February 12, 2006 Share Posted February 12, 2006 OK, everyone understand. It is not really lost, just not converted into the energy you were trying to make. It may either be not converted or converted into another form of energy. Perpetual energy machine does not exist. Maybe you should make one that runs off of cold fusion instead. Which by the way, is theoretically possible as opposed to perpetual energy. Quote Link to comment Share on other sites More sharing options...
Guest SouthGaZX Posted February 12, 2006 Share Posted February 12, 2006 so... windmills dont create energy (i know they dont actually MAKE the energy they just convert it from wind energy to electricity) and... toyota already has something like what i was talking about? well that bites.. so in theory you COULD put a magnet around a coil inside your wheel.. and recharge your batteries? or is that what toyota is already doing?

Yes, that's what a motor is. It converts electric energy into kinetic (motion) energy and some heat. Or the same hardware can be a generator and convert kinetic energy into electric energy and some heat. Yes, that's what Toyota is doing.

Lewis Maudlin Posted February 13, 2006 Share Posted February 13, 2006 The answer to your wheel question is yes. You could make the wheel into an alternator. However, the energy you got would be less than the energy that it takes to turn the wheel. The resistance caused by the magnet setup is greater than the energy produced. No such thing as free energy.

TheNeedForZ Posted February 13, 2006 Share Posted February 13, 2006 .. so in theory you COULD put a magnet around a coil inside your wheel.. and recharge your batteries? or is that what toyota is already doing? Like Lewis said, if the wheel is made into an alternator that is working ALL THE TIME, then the setup is actually doing negative work. What the gas-electric car does is to couple the rotating part of the car with a generator when braking or when going downhill. The generator requires torque to be turned so it helps you brake while converting some motion energy back into electricity. If you make your wheels into alternators, you should break the circuit when you are accelrating/driving, but close the alternator circuit when you are braking or going downhill. That would work properly. However to make the conversion more efficient, you should have something that spins faster coupled with a generator, like flywheel instead of the wheel.
