perpetual? i dono what to call it. Well just to remind you, a pulley divides the amount of work taken by the number of pulleys in the system. Well lets combine linear and circular motion shall we. Lets put a bar connected on a wheel attached to a motor that it's rotation point is on one edge of the bar, and the side edge of the wheel. the bar must be larger than the radius of the wheel to work, I would go with 2xr, then connect the other end of the bar to another bar held horizontally through a hole in something that has wheels on the top and bottom, so that when the machine wheel spins, the bar pushes the other bar forward and back horizontally. Well lets take a look, we can now connect a chain inside a rubber tube to the end of that bar and run it through a series of 20 pulleys, or more, who cares. the pulleys closest to the machine need to be on a fixed, but rotational pole, and the other on a rotational bar, underneath a rotating shaft connected to a large gear ( this bar must be the same radius as the wheel to rotation point). The chain will require a spring on it with almost the same spring constant as the force needed to bend the links in the metal chain, but considerably less. this gear will spin much smaller gears really fast, so then we attach 10 generators to this gear, and then there must also be another wheel/bar/pulley get up on the opposite side, running at the same speed as the other, simultaneously, but at opposite points on the wheel, so that one pulls as the other pushes, it would be most appropriate if you had 6+ generators hooked up at equal degrees with each other. and each with the corresponding positioning of pulling when needed. And there you have it, a very SIMPLE perpetual motion machine..!! Why does it work? lets put this equasion out there for one generator: lets say it makes enough electrical force to power 1000 newtons (theoretically), and it is required 2000 newtons to keep it in constant motion. Well you would need all 6 generators to run at 100 newtons each, x20 force, leaving you with 400 surplus newtons, add more pullies if need be. © Jared Andrew Ashby 2-24-2007 Any attempt to construct a machine, or sell the idea of this machine must first be approved by the original concept creator, Jared Andrew Ashby.
