Gravity Assisted Generator
« on: February 18, 2023, 09:32:17 PM »
Hello,


I didn't know how to exactly explain this idea, so I drew a picture. Hopefully it is self explanatory.


For it to work though, you would have to start it manually until it reaches a certain speed, then after that it would self run. Once that happens, you can feed the output back into the input.


What do you think?

It looks like the same principle as the Skinner machine but much simpler to build.  With the  proper gearing for a generator it might work.  Are you going to try and build it?

looks sorta like this

Now make one of those dual oscillating pendulums and rig it to that machine.  Design is so the rotation is in resonance with the pendulum weight motion.

Hi,
Yes, it's pretty much where I got the idea from.
Unfortunately, I don't have the skills, space, or tools to build this. 😔
Maybe I can pay someone to build it for me, I don't know. 😕
Maybe someone in this forum can build it.

Yes, basically the same principle, but built different.

Just a side note:


You would have to play around with the size of the wheel, the length of the seesaw, the weight on the wheel, and what motor/generator to use, and see what works best.


I wonder if someone on the forum can build this in some kind of physics simulation, or maybe someone can build a real life model.

The Skinner device is shown to be under unity. The reason for this is the same as any other OB gravity wheel.

To make the wheel turn, you need to lift the side with the weight on it. You add Potential energy to the system. You get the same amount of kinetic energy back from the weight flopping over as you put in from lifting it. This is reasonably easy to calculate, it is a 0 sum game unfortunately.

It doesn't matter what angle you use, the length of the radius or mass of the weight.

And in case Milcovic's two pendulum will be it the same ? :(

Milkovic does work on a different principle. And it is much more difficult to calculate.

I built something that most wouldn't realise is a rotary milkovic. It used the CF to pull up a wieght that drove the "swing".  I could not get it to reset...

I also tested the milkovic directly, but didn't get a gain either from the swing or from operating the see-saw lever end.

All the replications and modifications I have seen have been unsuccessful. Any claims of 10x power are wrong. You could get a multiplication of force, but still not OU IMO.

Anyway, you shouldn't just take my word for it, perhaps my tests were flawed or I might be motivated to steer you away. The best way to understand something is to actually understand  it.

This is the "ideal" overbalance path. It does not work.

See the similarity? Imagine the weight movement of the proposed design in 2D...

Anyway, thanks for posting the design. It is a good progression of the design shown in the youtube.

Do you have some evidence that the Skinner device is under unity?  Gravity is a force, just like the wind.  We use windmills to harness the wind energy.  The Skinner device appears to harness the force of gravity in the same way a windmill harnesses the force of the wind.  How do you explain that he is using a very small motor to run his device and then his device is able to run some machine shop tools?

Here’s a demo from several years back.

https://youtu.be/X4ppw8N0gfE

I had no problem in accelerating the wheel once the rhythm was found. The Skinner device is really quite interesting. Mechanical energy amplifier?

Cheers Grum.

But from what I understand, sure you're lifting the weight, at first..but once the weight gains speed as it rotates it won't be as heavy, at that point you're just keeping the rotation going with very little effort using the seesaw. The faster it spins the shorter the stroke from the seesaw, and the less effort needed to keep the wheel spinning.


I could be wrong. 🤷‍♂️

The Skinner device acts like a flywheel. It doesn't get easier to lift. As it coasts, it lifts less. As you apply a load, the heavy weight lags and is lifted more. In the above device, the weight will be it more difficult to lift with CF/CP. Like the SD, Freeenergy's design will also act like a flywheel, and will coast, except when you add a load. The load will be reflected by slowing the weight back to where it lifts more, making it harder to lift, all the way back to the input.

The ultimate test for any OU device is: If it outputs more energy than it inputs, you should have enough to loop the power to drive the device and have some left over. If Skinners model had so much energy, why didn't he loop it? This could have been done either mechanically or electrically.

Again, If you think the SD is OU, just bujild it. It isn't hard, you just need a decent alternator/generator. A wattage meter is cheap to buy, but only accurate if it is used correctly. In this case it can be used to compare load vs no load power draw on the device on the input.

Grumage, I don't think your video has much to do with the skinner device, and I wouldn't class it as an "Overbalanced wheel" although you are still adding Potential energy to it as the weight lifts to keep it running.
