Whoah. That's an excellent video, and it shows how this was far more complicated than the simplified diagram in Wikipedia: the device was over 300 meters long!
Indeed, the diagram (and the wiki text too?) don't make it clear how many towers were involved, so it looks a more complicated solution that would be needed.
The power transmission to the spoons remind me of the rod line powered jack pumps in early oil fields. You can still find 100 year old wells with that kind of power distribution but they are rare
