here's a good 2m30s youtube that shows 15kW one in action: https://www.youtube.com/watch?v=gY3p2e1-kN4 https://www.youtube.com/watch?v=gY3p2e1-kN4 its amazing

here's a good 2m30s youtube that shows 15kW one in action: https://www.youtube.com/watch?v=gY3p2e1-kN4 https://www.youtube.com/watch?v=gY3p2e1-kN4 its amazing how little there is to it, and how relatively quiet it is.

Interesting, this is a bit different design... it appears water has to "fall through" that turbine, rather than using the "stirring force" per the wikipedia article.

  Not really the same at all. The gravitation water vortex power plant is designed in such a way that fish can easily go through in both directions because the turbine is in the upper, not lower portion of the vortex, leaving the drain clear for fish (and a certain extent, debris) to pass through. This is just a turbine installed in the drain. It's really not much different than a traditional hydro plant.

It's pretty cool so see a combination of manufacturing, installation, and operation. For a distributed power grid this might be a clever addition, add some solar, wind and perhaps battery-backed buffer and emergency fuel-powered generator and you might have yourself a pretty reliable self-sustained power source. I imagine out of those, the wind one might need the most maintenance, or if a lot of crap comes down, the solar panels need periodic cleaning. I wonder what maintenance this generator needs, besides the obvious stuff (brushes? lube on contact points? bearings?).

  Wind is random, the hydroelectric generator could act as battery, drawing current to compensate the lack of wind.

Just for an order of magnitude, even if it’s not the same usage: - One nuclear core: 700MW - Or 50.000 of those microhydraulic turbines.

  Although it'd be pretty cool to have a reactor in the basement..

    Well, technically it would be pretty hot...
