Each time society approaches depletion of another natural resource it feels the Supply & Demand economic pinch. Attention then bounces to another resource, until the pinch comes again. It's a vicious cycle that no business or community wants to face.
The Water Horse is Different...
Instead of maximizing point source extraction- which invariably leads to depletion- the Water Horse strikes a balance between the rate of extraction and the river's ability to regenerate itself.
The physics behind this thinking opens the opportunity to harvest energy from river flows previously considered "technically unrecoverable". Best of all, moving the focus away from maximized point source extraction enables a simple, cost effective design that is sensitive to the economic side of the eco-balance.
