well, another of my should work but really won't ideas is: in deep space build a power plant shuch as the one in the attachment, but the attachment button is not working so, here is how it works: make any number of turbines(generators) with elec. motors powering them take all the output wires and connect them to the motors as long as the generator make more elec. than the motors need then it should runforever being in deep space with no forces to slow it down (no heat,gravity,air,friction... you get the idea.) and even better if the generator make more than what the motors need then you can get an output but i just realized to get a magnet in space you would have to use electomagenets and to top that it would never make an out put as all the energy you put in the magnets and motors is all you are going to get out so all it really is is one HUGE battery well at least it will sustain it self forever. | ||

Another shouldn't work and won't work idea. The generators can't make more power than the motors need. Even in 0G, without wind resistance, the generators need more mechanical input than they can convert to electrical output. They will always be far below 100% efficiency. As a corollary, the motors will need more electrical input than they can deliver as mechanical output. They, too, will be far below 100% efficiency. Always. At 0G. At Absolute Zero. At 0Cd. You will not attain unity, let alone exceed it. (Message edited by michaelt on March 27, 2006) | ||

You can make a light mill anyways it vacuum in space right? Then connect it to a dc motor. | ||

No. The light mill needs some gas to operate normally. Without any gas, it is thousands of times weaker, and goes in the opposite direction. But it is an entirely different subject from what the first two poster were talking about. Using a light mill to spin a generator is just another way to build a solar power system. Using solar cells would be cheaper and easier, and would have no moving parts to wear out. | ||

hey i admitted at the end that i finally realized that the motors won't make more power than it needs. you can't make energy out of nothing | ||

Anyone who has seen a physics textbook can know it is imposible - energy is not lost or created, it is only transfered. | ||

I see the debate goes on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and on and oh hell, I desist. Well, maybe just one comment... Free energy? Free Friction. | ||

yes yes i know but all your posts go in the "read before you post" category i said that right after i wrote the first post and started the topic that i realized tha nothing would be made.read post #4 | ||

why can't you take a magnet in space? | ||

Because I don't have that big a rocket. Seriously, though, your question shows that you don't understand how generators work. They convert the energy in the motion of the wire with respect to the magnet into electricity. Since the energy comes from the motion, as you deplete the energy, you slow down the motion. Eventually, it stops. Take a small electric motor, and spin the axle with your fingers. It spins freely for a while after you let go, because there is nothing but a little friction to slow it down. Now put an LED across the terminals of the motor, so it becomes a generator and lights the LED when you spin it. Now it doesn't spin very long at all after you let go, since that energy is going into making the LED light up. Since an LED is a diode, and only lights up when the current is going the right direction, you now have a neat little demonstration of where the energy comes from. Because now you can spin the motor one way, and light the LED and watch the generator stop, or you can spin it the other way, and it spins freely for a while, because no energy is being taken out to light the LED. | ||

I asked why can't you take a magnet in space because i tought that they would get demagnetised or something. It was a verry stupid question!!! | ||

James - doesnt everyone have a bad habit of doing that? I use the 'last week' link, how should i say, way too gratuitously? Actually in my case, on this subject, it's just my little way of saying that I still check in from time to time in the perpetual motion arena, to see what kind of whacky idea is out there at the moment... even though I know its not possible (not begging for an argument here, REALLY!  ), I still find it fascinating - it shows how creative the human mind really is. That is all, oh great ones. Dismissed! (Message edited by madscientist on May 4, 2006) |
