Hi; no sorry "conservation of energy" means (conventional thinking says) perpetual motion is impossible. there is always energy bled out of a system by heat and friction. let me take a shot at applying this here without the math of bearden's psuedo science.

hello, last night I went to bed and this idea popped into my head, when I woke up the next morning I drew it in ms paint lol. I know there will be something wrong with this but from my point of view it seems like it works.
basically I need someone to tell me why it wouldn't work
pretty much, its just a vertical tube, which has gears on the side, and a spring at the bottom. a ball or something is put at the top, and as gravity makes the ball fall to the bottom spring, it makes the gears on the side turn and wind up the spring while charging a battery at the same time. when the ball hits the bottom spring, the spring releases and sends the ball back to the top of the vertical tube, repeating the process
sorry if my picture is sloppy, and not completely finished, because it's just an idea, and I haven't worked everything out yet.

magnetic vibration and the helix are the answer

I don't understand how you expect the gears to turn because of the ball... They don't just magically turn as the ball goes by you know. You have to take into account that the spring will deteriorate over time, and to make sure the ball carries the same trajectory over and over again. You also need friction between the ball and gear, and that will slow the ball's speed, and as it gets slower, the spring will contract less. It won't run perpetually.edit on 27-11-2010 by Somehumanbeing because: (no reason given)
Please provide a source for that claim, I don't think it's true and while the sun's expansion in a few billion years will screw up some orbits in our neighborhood, I don't know of any reason a planet couldn't orbit around a brown dwarf (or some object that won't swallow up orbiting bodies like our sun will) perpetually.

No...all orbits degrade over time...even our moon's orbit, and those of the planets.
In theory, perpetual motion can be understood to be in line with the science of physics. As an example, two objects in orbit around one another could conceivably remain in a perpetual state of orbit as long as no third object was introduced into the orbital cycle.
