This is an exaggerated edition of how a gravity generator could work. The final version would have 20 - 30 smaller weights falling in on a mechanical trigger that releases the next weight in line, thus creating a chain reaction.
It took forever to simulate in Blender (I'm no 3D artist or engineer), so I ended up with this grotesque version of a gravity generator. It was intended to be something that could be embedded in the walls of an apartment, like a hollow wall you could install yourself.
I have been thinking about doing a rough edition in Blender, so it could be simulated. Animating a series of 20 weights by hand would be a nightmare. :-)
Before making the simulation in Blender, I had to "develop" the mechanical trigger that released the weights. Since I am not a mechanical engineer, it took me months of pondering. I first thought of an electrical trigger with a small motor, but that would subtract from the energy produced, and I was not sure how much energy was needed, so it made more sense to make a mechanical trigger.
The main idea is to have a series of small weights, each a size of a liter in volume, falling one by one. The weights work as a mechanical battery, and the charging is to raise the weights manually. Powered by human hands! Fitness included!
A way to extend the time that the weights take to fall, which would cause a decrease in the energy released, would be to introduce pullies. Pullies could multiply the length of the rope needed since the weights are not directly coupled to the rope pulling the wheel, turning the generator. Pullies would also introduce more friction, but maybe a solution exists to minimize that?
Please let me know in the comments about pullies with the slightest possible friction you know of?
Maybe standard pullies already have a small friction since it would hinder their function? :-)
One problem that I have yet to be able to solve so far is the size of the spool of wire needed and how the rewind it efficiently. It potentially could take hours to rewind :-( And the size of the spool could end up being unpractical in an apartment space. Then comes the wear of the wire! Since it is a considerable amount of weight pulling on the wire. Even with ball bearings on every contact point on the wire, the wear could be the thing that killed this idea :-(
