Mr. Fields, I need help with my Science project, definetly and you being really knowlegable I thought you could help me, it's just I am looking at something that would help me in a Science Project over here in the British Isles. As an enviromentalist I have always been interested in ideas that would show the world that there is an alternative to oil and other fossil fuels. I have seen tonnes of ideas, and had a few myself about perpetual motion or at least partially sustainable generation of electricity, such as a clyindrical tube with two springs at each end, and a coil of wire in the centre, a magnet with two pieces of plastic at each end would enable me to send it up and down through the coil of wire without sticking to the springs. Please help me. | ||

Friction would slow it down, even if you could get abosolutly NO friction it would only store energy not create it. To make absoluitly no friction you would need a vacuum with nothing in it, not even radiation. Of course this is impossible, it might be possible in a fiew mellenia of technological advancements. And with the discovery of dark energy this would probablly make it impossible at any level of technology. PS: The only perpetual motion machine is the entire universe itself since energy cannot be created or destroyed. Matt | ||

Hi, I know it is hard at first, but you have to accept the fact that perpetual motion cannot be a possibility - even I have spent my a few months of my teenage years figuring any feasable means to achieve perpetual energy with little success; it is only know that I have made my decision to step away from that route or I will waste my whole life achieving nothing. The only "sustainable" energy source I have been thinking recently is to do with thermocouples or ways to move a magnet through a coil by any necessary means possible. I too am an environmentalist trying to make things that will provide some form of cleaner energy by the least. Other things I have been thinking about was my idea about creating an array of heavy flywheels attached to generators and step-up-ratio gears that can be bicycle started for about an hour, which will keep spinning at relatively high speeds for a week or so. Just try to keep an open mind though, you never know what surprises nature will through at you! Or look at the movement of trees and watch their branches sway in the wind. I've been thinking of other ways to generate energy using the wind without necessarily using propellers. You could try attaching blocked of neodymium magnets to a stretchy band and put it outside and let the wind move it up and down a coil. | ||

Since people here are using such a loose definition of perpetual motion, let me disprove everyone here. Since the Earth is in perpetual motion, all you need to do is to lay out a wide, round body of water in a container with greased walls. Then you'll have an object that'll perpetually turn, once a day. I want someone to try the following, as I've thought about it earlier with belts though such may be harder and pricier to pull off: Cut a whole gap in the wall of this container, and fit a narrow, gapped container with the same height also filled with water. See if this water does anything special. | ||

there is no such thing as perpetual motion, anywhere. The earth is certainly not in perpetual motion. A body of water in a container with greasy walls is not perpetual motion. Let me remind many people that there are two types of perpetual motion. To physicists, perpetual motion is where an object in motion stays in motion, forever. To an engineer, perpetual motion is where an object remains in motion for a long period of time, long enough to be considered perpetual but eventually will come to a stop (i.e. for the next 10'000 years). Unless you are some engineer, then you might as well consider the orbit of the earth perpetual as it will continue to orbit round the sun for the next few billion years. Since all of us here seem to be physicists, in retrorespect then you should all accept the fact that there is no such thing as perpetual motion. You cannot prove the existence of perpetual motion, nor can you disprove it, so please stop claiming that perpetual motion is posssible. If you can design and construct a perpetual motion device that seems to keep moving or rotating at a constant rate that never slows down, ever, not for a day, or even a whole year, i would very, very much would like to see it  | ||

vocasla says " You cannot prove the existence of perpetual motion, nor can you disprove it, so please stop claiming that perpetual motion is posssible." you say it cannot be proven or disproven so quit saying its possible then by your own words you have to quit saying it isn't possible either. and for fun try this little experiment you'll need 13 neodymium magnets in a disc shape then you'll need 4 in a washer shape but about 1/4 in. thick plus about 4 to 5 feet of dowel rods. take 8 of the magnets and place them in a circle on a board atop dowel rods at whatever height you wish like the numbers on a clock then construct a star shaped gear with 5 points not an elaborate one just 5 rods coming from the center then connect them to a longer rod (these are of course wood by the way) so what you have looks kinda like the ship on deep space 9. then take the washer ones and attach one to the bottom board you have the clock thing on and one to the middle rod (leaving enough rod sticking through to go through the bottom washer to hold it in place.) ((may want to place the bottom and top constructs ina tube so there is a levitation effect in place and the whole thing wont fly away. do the same to the top of the middle rod (of course youll have to suspend another board in the air using the ta da dowel rods.) then align the star with the magnets in the circle. (oh i forgot to mention the disc magnets need to be very thing on the outer ring and slightly thicker on the star) then make sure the outer magnets all have their polarities the same + - + - + - etc. for all 8 then on the star make the polarities the opposite. now if my theory is correct the outer magnets will pull the inner magnets and if there is enough initial velocity the magnet will pass to the other side of the magnet nd push the magnet away and that may just keep it turning for a while. ( lol you're gonna love this each of the 5 points needs 2 magnets so its like this +I--I+ a pushmepullyou. getting to stay together wont be easy but im sure you'll find a way if you try this.this would all be better if you could get triangle shaped magnets for the outer ringthat way there is a thinner point for the free moving magnets to pass | ||

The magnets will move to their lowest energy state and stay there. What you are suggesting is the same as putting a car on a hilly road and saying it will coast down one hill and then up the other forever. It will coast down the hill, coast a little ways up the next, and then back down, and eventually sit at the bottom of the first hill. | ||

PREPUTIAL MOTION IDEA a one way get a one way tinted glass sphere with a mirror on the inside put a soler celll in the center adn to wirescomeing out of the cell 200% !!!!!!!!!!!!!!!!!!!!!!!! | ||

I suspect you don't understand how "one way glass" actually works. Also, you should try the spell checker built into the Google Toolbar. It will really help you communicate better, and people will be less likely to be dismissive of your ideas. | ||

i have invented a perpetual motion electric generator, no, really i have. any questions E-mail me at: JTHEKID@MSN.COM | ||

Great. I'll buy the electricity you make, since it should be very cheap. I will pay you a penny a kilowatt-hour, and we will both get rich. What's that you say? You haven't actually built one yet? Call me when you are ready to sell me some electricity. | ||

30 years ago I was playing around with magnets. some disc's we're hanging in my room on a string put some magnets on that disc it began to spin and kept spinning tell it tangled the string like when your telephone cord gets tangled. can anyone help me to understand whats going on! I can replacate the this as many time as I need to. csanderlin1234@aol.com | ||

Send us enough detail to reproduce the phenomenon, and someone here might be able to tell you what is going on. | ||

Perpetual motion isnt impossible, it simply isnt feasible with our current techologies. If nobody ever tried to defy physics, wed still be saying that the earth is the center of the universe. And those who fume that perpetual motion, or 'energy from nothing' is impossible, you are simply saying that creation did not happen, that the big bang is not real, and galaxies are hurtling away from each other for a reason other than the big bang. The fact that we are here demands that creation occurred, and creation demands 'something from nothing' | ||

It seems to me that there are other alternatives. Perhaps the matter and energy were always there. Perhaps the brane theory folks are right, and the big bang happened when 11th dimensional membranes collided and produced our 3 dimensional big bang. There is no 'demand' for creation, other than by theologists. If there was originally nothing, then what would cause it to change? And if it changed, why didn't it change sooner? The argument is as silly as postulating that some magic turtle created the universe. It begs the question of how the turtle got there. | ||

A perpetual motion machine is NOT possible. And you can't get energy from a zero-point energy device. Zero-point energy is absolute lowest temperature. However, a Semi-perpetual motion machine is possible. It is NOT "forever", but It's magnetic propelled mechanism will last very long. No continuous external source of input is required. The propulsion (input source) comes from several permanent magnets precisely fixed on several large heavy discs with axles and high torque one-way clutch bearings. But it still must be maintained (with minimal maintenance), eventually it's parts will weaken / degrade. The magnets will wear out, just simply replace/recharge the magnets. Eventually the bearings will need lubricated and replaced.... Only by using the power in permanent magnets, can prove that a self propelling machine that is powerful enough to spin a high power generator is possible. contact me with your thoughts www.rjflash.com |
