Gravity Wheel

[Wubbly]

Nice builds Robert!

[Calloway]

After experimenting with this build all week I have found that I just can't make the slider weights travel up the entire distance of the track before the 180 degree horizontal line. The pendulums do not have enough travel in the swing for this to happen. Pulling or pushing and you run into bad glove interference by trying. Imo

I will put this idea to the side for now.

I bet myself a beer that I could maybe get this design to work.

I lost but still enjoyed my beer...:)

Keep in mind that even if your design doesn't work, Bessler talked about a prime-mover as if being a 2nd and separate mechanism. So even if you haven't found the prime mover, your idea might very well be a power-amplifier once a prime mover was fitted to it. Thanks for sharing your progress!

Silent, You are correct. My design didn't work, but maybe someone else can take parts of the idea and combine it with something that will. Sharing ideas is so important.

I really think pendulums will play a part in a successful design. They can be used to move or flip weights. Imo.

Like you, after all I just want to charge my cell phone for nothing using a gravity wheel.

Know that you have worked on the centre sliders. Hopefully you have 2 sliders crossing the axis using 4 masses.

It would be good for you to look at long pendulums with rods instead of string.
Also look into ratchets to stop the pendulum swinging.

P.S. you are working on two separate devices 1. the sliders 2. the pendulums.

I need for someone to settle a argument between me and myself. Let me retreat a bit. I have always considered that this design needs a proper differential in weight between the pendulum and slider weight pair. I reduced the slider weight pairs which increases differential but increases travel and have seen great results which I will show in a later video. My question is: Would the swing of the pendulum be considered to contribute from a open or closed system of the wheel? If open where does the extra energy come from? The more speed the wheel has, the more force it seems gets released from the pendulum to the slider weights. If closed, where does the extra energy come from? I have to figure this out. Thoughts on a pendulum attached to a wheel?

I think it can be considered an open circuit.
The energy being transfered from the wheel to the pendulum is a loss to the wheel. The effieciency of the pendulum allows the energy to be returned to the wheel at a later moment in time.
If the movement of the weights caused by the pendulum has reestablished an identical state to the intitiel state, then the situation becomes a continually trying to "catch up" state, which i don't think can be considered as closed.
Just my two bob worth.
I'm looking forward to the video.

I thought I would pass along some new information on this slider design. The problem has always been getting the slider weights picked up before the 180 degree horizontal line. I have finally come across a simple method to do so. It requires that the pendulum weight be attached to the slider weight by a cord. The pendulum main cord is attached to the outside of the wheel. The pendulum weight wants to continue to stay vertical so it pulls the slider up which is attached to the other slider by a cord. The slider pair continues up BEFORE the 180 horizontal line. I suspect that some of the sliders weight is also being transferred to the pendulum weight which is desirable It works very smoothly. Because up is down and down is up on the opposite side of the wheel, you have slack in the pendulum slider weight cord to pull the slider weight pair back as the wheel comes around. I will post a pic and video at a later date. I'm feeling very tired lately so I wanted at least release this info as it may help someone.

Calloway,

You are on the right track. The sliders can go away, you don't need them. If the pendulums swing in on the up side and temporarily lock to the wheel it will be
OOB, and take off like a shot!

A one-way clutch will automatically lock and unlock the pendulums, to the wheel, all you have to do is to find a way to flip them. You can experiment with and old bicycle clutch, to see how the clutches work.

For some reason it's better to swing the pends. in on the up side rather than out on the down side. Also, it's better if they don't do any thing on the down side. That way they can't get into any trouble-------------------Sam

[Calloway]

Hey Sam! You know I have tried your method using one way bearings. It seems like it should work. My problem was how do you kick the stiff pendulums out?? I never could figure out a method to do that. I could do it with electricity , but that don't count. I could make it turn all day as long as I flipped the pendulums out by hand. Maybe you got that figured out?

My idea takes the weight of the pendulum and pulls the slider weights up. The pendulum weight can be a heavy as needed as long as they are all the same. 8 with my design. The slider weights unbalance the wheel. I'm experimenting with mounting points for the pendulums which gives the best angle and power to lift the slider weights.

Best of Luck

Calloway,

You have a good Idea, seams like it should work. Anyway, good luck with it-----------------Sam

Calloway,

FWEIW, I did find a way to flip the pendulums, like so: Fasten a short horizontal link about an inch long and down an inch or so below the pivot point of the pend. At the end of the link is a pin or bolt sticking out. I call this the offset.

With the pend. at the 9:00 O' Clock position, the link / pin is pointing towards the center of the wheel. Stretch a spring loosely from this pin to a pin near center of the wheel.

When the wheel turns 180 degrees to 3:00 O' Clock, it will stretch the spring two inches and flip the pendulum into the center! Which is great except, it also tends to swing the pend. into the center on the down side, not as much but enough to screw things up----------------------Sam

Here is how to pickup the slider weights.
