I came up with the idea of how the ascending and descending technologies should look and work. The screenshot is a draft, and it's not yet possible to understand anything from it:) but the stone moved:)

I had many ideas, but in the end, I came up with end scheme unexpectedly - since I don't remember physics at all, I thought  - what if sound, very abstractly, as spoken words, can be converted into energy. And energy - then further either into heat or into electricity.

It turned out that such researches are actually real, and there are even several scientific projects that set the goal of, for example, converting the sound of passing trains into a small amount of electricity. Reading super interesting - and from there you can get 100% inspiration immediately.
