On Amazon you mentioned you had a way to make the gravity light sold there, last an hour rather than 20 minutes, which video on your channel covers that particular information please?
The first time I used the Gravity Light for output was here, "Hydro Lifter Water Wheel and Gravity Light" , "ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Rp_7wIlgMCI.html". You can see in the current video where I use the generator, gear box and sat lights from a Gravity Light in a couple of drop test. In each case I had to modify or use the components from a Gravity Light. Sorry, but the Gravity Light, as it comes, will only give you 20 to 25 minutes without some modification. The bead chain only allows for an eight foot drop.
Just wanted to add that they have the next Gravity Light in development. Just search on Google for "nowlight". It isn't powered by gravity and is suppose to be a real improvement over the previous version. With a little modification I hope to get one to work with a Lifter.
Actually..I thought about gravity battery..ok..but your system being complexity... counter loading is acceptable...but better need roping ratio.. which is much effortless..so that...the main primover doesn't lose its possessed energy level...I had try s design..on paper..
