Starting gravity wheel project, GRAM
« on: June 02, 2014, 03:57:15 PM »
Hi, I completed the fabrication of a test fixture. I am using ratcheting box ends to form weighted pendulums that will only swing in one direction. So on one side of the wheel the weight will be a pendulum and move toward the axle and on the other side it will extend and  form a weighted lever arm. Basically the system finds equilibrium and stops.  I am adding ramps with magnet rails to extend the weights to form the lever arm.

Short video of manual operation.

 The pull force required to extend the weight to the end of the ramp is < 5 pounds. Suggestions for the magnet rails are welcome.

Here's a suggestion.

Lock down all moving parts except the main axle/wheel. Then apply a known turning force to start the apparatus and time how long it takes to coast to a stop. Call this the "baseline rundown".

Now free up all moving parts so that they move according to your plan. Apply the same known turning force as you applied in Part 1. Time how long it takes to coast to a stop. Call this an "experimental trial".

Do each condition ten times or so and get average times for each condition.


Compare the average Experimental Trial rundown time with the average Baseline Rundown time. Which is greater? Does it help, or hurt, to have moving stuff on your wheel?

Once you have a solid Baseline Rundown time, you can now tell if any of your alterations or changes or additions are actually _improvements_ or not, by repeating trials, using the known starting force each time.

You can generate the repeatable starting force by, for example, wrapping a string around the axle or the periphery of the main wheel, having a weight on the string end, and letting the weight fall a known distance, pulling the string to rotate the wheel. The energy imparted by the descending weight will be mgh: m is the mass in kilograms, g is the acceleration due to gravity 9.81 m/sec2, and h is the distance through which the weight falls while pulling the wheel by the string. There are other ways as well, to inject a known and repeatable starting impulse to the wheel.

So you are injecting a known energy value mgh each time. The wheel will turn for more time, or less time, depending on alterations and what is moving. If you ever get an Experimental Trial series of rundown times that is _less_ than the baseline rundown, you will then know _for sure_ that your improvement or alteration is actually helping rather than hurting.

You can also buy excellent and low-cost "one way bearings" to replace your lossy ratchets, at the local RC Helicopter supply store.

Hi, thanks for the input. The configuration I was trying proved to have to many problems.

PMA installed, it will now function as a manually operated gravity assisted electric generator. AC 3 phase radial flux PMA.

Hi, I identified the problem areas and determined the design is becoming to complicated to fabricate. I found a similar design to the William F. Skinner device and started fabrication.

I have to finish drive train and gearbox than I will post results when available. It is much easier to fabricate and still uses gravity and a mechanical assist to operate.

 nice work on the William F Skinner device approach. I am keeping an eye on your progress.

I did a simple test today. I took all the weights off and started the motor. The tilt plate just moved up and down and did not rotate. The output shaft is definitely powered by the weights falling toward the the center of gravity. No weights on the tilt plate, no rotation at the output shaft.

I still have to fabricate a few more parts to connect the PMA. It should be a few more days.

Hi, the PMA is  mounted. I still have to complete the wiring, than I can test and post results.

Hi,  I did a manual test today with really poor results. Based on what I experienced I see no reason to continue this project. My analysis of how this  configuration should work is wrong. I had 60 pounds on the tilt and there was no benefit, in fact it made it was more difficult to turn.  I adjusted all the possible parameters that I could and my conclusion is there no way a small electric motor will make it operate.

The higher the lower weight is from the arm the less weight you need to use,, the faster it spins the less weight you need,, the angles are important, as well as the index of the arms to shafts.

With that being said you have got to about the same point that I have,, and that is with the system setup as it "appears" to be in the video it is a net zero device, meaning that you can get out what you put in.

I had a few outliers in my tests,, but by far the most consistent results were no gain to a loss,, and some of those losses were large, the best outlier that I had showed about a 2% possible gain,, but that could of only been a decrease in the frictional losses my testbed had and not a real gain,, that is most likely the case.

No problem,, I posted some of my results and stuff in the Skinner thread.

Have in mind that any lock-ups, and other movenents in the pendulums will require some sort of torque, counter torque, lost and gained energy to orientate.
Isolate every weight movements in this wheel, and analyze them separately. Do you see any reason why these movements separately, or the gravity wheel as a whole, should gain energy for each revolution by itself then?


The basic and fundamental workings of a "gravity wheel" is that all the weights that is put into the wheel, no matter how they orient themself during one revolution, are limited within a given and "fixed" change in altitude from ground.
As we all know, a given weight at a given altitude carries potential energy which is a product of those two.
As the weights in a "gravity wheel" never change their most and least potential energy, there cannot be possible to harvest excess energy - since the excess energy is zero.

It is not about making excess energy,, it is all about using the energy as it is constantly cycled within the system,, you pump it up and that it is your input, Then the system is moving it around and that has work involved and that is what you get to get in the middle of.
