In a fairly radical departure from the principles that normally govern hydroelectric power generation, Austrian engineer Franz Zotlöterer has constructed a low-head power plant that makes use of the kinetic energy inherent in an artificially induced vortex. The water’s vortex energy is collected by a slow moving, large-surface water wheel, making the power station transparent to fish – there are no large pressure differences built up, as happens in normal turbines.

>” […] The aspect of the power plant reminds a bit of an upside-down snail – through a large, straight inlet the water enters tangentially into a round basin, forming a powerful vortex, which finds its outlet at the center bottom of the shallow basin. The turbine does not work on pressure differential but on the dynamic force of the vortex. Not only does this power plant produce a useful output of electricity, it also aerates the…
