Well, okay, not exactly.

Water Vortex Drives Power Plant
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.
