Cool idea! Any idea if this tech is more efficient than large-scale dams? Or just packaged into a smaller footprint?

Looks like this is the company that builds them: https://www.turbulent.be/

I think that the future of power production is distributed, interconnected microgrids. Each micro-grid has a power source that can supply power to its local community. These power sources can be anything from small hydro turbines like in this post to small modular nuclear reactors. These power plants are subsidized and bootstrapped by Bitcoin mining. Excess energy is either sold to other nearby communities or sent to miners.

Anyone curious about this concept should read "Bitcoin is a Pioneer Species" by Brandon Quittem. Its also been read by Guy Swann on Bitcoin Audible. Just look up read #596.
