Planetary System using centrifugal forces

[adversarius]

Hello friends,

I want to present to you a mechanical system that uses (reactive) centrifugal forces to do work.

Centech.org - Planetary System

I have analyzed all forces and torques and I am certain that it should work. The semi-circular rotors do the work and can drive a generator that would be fixed at the outer gears. There has been no prototype build yet. Since everything on the site is published under open source everyone is free to build one.

By the way, I do think that energy really is created here, no conversion of vacuum energy or the like. There are examples on the site which show that it is possible to create energy just using classical mechanics.

If you think that it won't work, please tell me. Don't hesitate to ask any questions.


All the best

Hello adversarius!

Well, I'm no mechanical expert, but I replicated your simulation in Algodo (I'm no Algodo expert either) and I could "extract" only about half the energy I put in.
I first ran the simulation with no load at speed 1x, waited for it to stabilize and counted the rpm on the big flywheel. Then I repeated the process with the "load" on and got only half the rpm.
The "load" were the motors on the weights axles set to rotate in the same direction as the outer wheels (simulating loaded generator action). the two motors were set to a quarter of the torque but the same speed as the motor on the big flywheel.
When simulated with "load" on, the weights were shifted by almost 90° in respect to the no load situation.

Are you willing to share your simulation file so others can play with it and see results?

Nice idea by the way, but no free lunch... at least for me...

Hi,

I don't trust Algodoo anymore since I found a major flaw in it. Others have also raised concerns that the numerical calculations are not correct. The simulation you can see on the website was made with Algodoo but only to show the movement of the system in a video.

Let's put it this way: If the flywheel gets slowed down while the semi-circular rotors do work, then the system does not work as supposed. But how could the flywheel be slowed down by the rotors? You are correct to point out that the semi-circular rotors move CCW due to the load torque when the flywheel rotates CW. Now the rotors are shifted, but that doesn't slow down the flywheel.

Centrifugal forces act radially outward from the center of rotation, so the centrifugal force acting on the rotors can't slow down the flywheel.

The load torque that is responsible for the "shifting" doesn't slow down the flywheel either because it doesn't act at the flywheel's axis.

But can you think of anything else that could potentially slow down the flywheel?

Hello again adversarius.

I looked at the simulation a second time and it is my opinion, that the load torque or any other resistance applied to the outer gears will slow down the flywheel, because the center gear is stationary - fixed to the background, so that is what the motor on the big flywheel works against, when the load is applied, but only until the centrifugal force of the rotors is overcome, so you can't apply to much of a load - at least not greater than the input motor torque.

In my opinion you don't need the rotors (weights), just apply the load between the flywheel (as stator) and the outer gears (as rotor), but now the efficiency of the system does not depend on the weights anymore.

So, this is how I see it...but, as I said before, I'm no expert and I might be just wrong...

Have a good one.

Hi,

No, as long as it is not a force that is acting on the outer gears but a torque, then there is no movement of the big flywheel. I have build a model and it shows just that (that's a flaw in algodoo by the way; if you apply a CW torque at the outer gears the flywheel will move CCW in algodoo, but that is not what happens in reality.)

My experience with the model:
If you apply a force at an inner gear, the flywheel moves; if you apply a torque, the flywheel does also move.
If you apply a force at an outer gear, the flywheel moves; if you apply a torque, the flywheel does not move.

In my opinion you don't need the rotors (weights), just apply the load between the flywheel (as stator) and the outer gears (as rotor)

This is a difference imho. In this case the rotor would be driven by the rotational energy of the flywheel. Imagine this: If you try to turn the flywheel in your configuration it would be harder to turn because you must overcome the load torque. But in my configuration it wouldn't be harder to turn because the centrifugal forces turn the rotor. This is how I see it.

Have a good one.

You too!

Hi again!

Well, if you built a model, than you're right from the begining and i'm wrong (but I blame it on Algodo )
Do you have any pictures to share? I'd like to build a model for myself to see how the thing works, but possibly without buying gears and stuff like that (don't have money to throw away at the moment).

Thanks and good luck!
