The concrete blocks are slowly hoisted upwards by motors powered with electricity from the Swiss power grid. As each block descends, the motors that lift the blocks start spinning in reverse, generating electricity that courses through the thick cables running down the side of the crane and onto the power grid. In the 30 seconds during which the blocks are descending, each one generates about one megawatt of electricity: enough to power roughly 1,000 homes.
There is a youtube-video from 2 years ago, debunking that idea: https://youtube.com/watch?v=NIhCuzxNvv0

was hoping someone would link this here.
So many recent “inventions” are just bad versions of already existing inventions. E.g. the gravity energy storage is already perfected in the pumped storage hydro power station, the Hyperloop is way worse than regular trains and so on and so forth…
But that’s irrelevant. You just have to vaguely overpromise stuff to investors and then get a clean exit to cash out.
