Will my perpetual motion machine work? It probably won't.

Hi all,

 

First post here, and I just had to make an account because I want my concept to be analyzed and/or shot down.

 

Basically, I'm considering how objects are heavier near earth than a few kilometers high.

What if I built some kind of belt that stands up a few kilometers, and brings weighted balls up (getting lighter as they rise, theoretically) on one side, and tips over to the other side of the belt when they reach the top.

 

The ball/s fall on this other side of the belt, possibly reaching terminal velocity, crashing on presumably a pool of balls that are weighing down this side of the belt. And since all of these balls are near the earth, they should exert more downwards force than the other side of the belt (the rising balls side)....

 

I haven't got it all worked out, but what do you think?

Please feel free to shoot down, scientific-community style!

The balls on one side of the belt would presumably match the balls on the other side of the belt, hence it wouldn't move by itself.

 

You should check out the theoretical concept of space elevators.

Some friendly advise....if the term perpetual motion is applied to any design you can count on it not working....also be extremely wary of claims of free energy or infinite energy there are no such things anywhere in the known universe (granted you could consider wind, solar, geothermal, and hydroelectric sources as free BUT to harness and use the energy is going to cost you as will maintaining the equipment).

Welcome to Hypography! Sorry about the perpetual motion machine.

And since all of these balls are near the earth, they should exert more downwards force than the other side of the belt (the rising balls side)....

The energy given by each ball's descent is equal to the work of raising it up on the first side. The dependence of weight on altitude is the same in both cases.

 

Further, the falling ball will be dispersing energy as it reaches high velocity, the crash won't be quite a perfect elastic collision and you need a complicated mechanism to convert the weight of many balls with the energy of the crash into what is necessary to drive the belt. You're devising a fancy way of having each ball bounce up and down, at the very best you can reduce losses to near zero.
