All the system energy was put in by me. My work was stored as potential energy in ft.lbs, then released as I wished. I had much fun in determining sticktion, friction, pulley and gear efficiency, generator efficiency, and relative efficiency of electrical storage devices. I handcut the gears myself, too, very tedious!

It might sound tedious to build a specific purpose machine, but don't give up. The gravity is there, as long as there is mass. But we need to think beyond gravity here folks. There are a lot more sources of energy in nature, so, we can combine them! Lets see, we use the gravity to pull down and generate power while we use solar or wind power to charge a system to pull the load back to the original position. This way, we keep both systems separate and renewable.
