Sustainable hydropower
December 16, 1996
Conventional rotor-based hydropower systems define power output in terms of potential energy.
P=HQw/550 or (P=HQw/100) Where: P=power; Q=mass flow rate cfm (cms); and w=weight of water
Because power equals head times mass flow rate, increasing power means increasing head. The result: monumental dams that devastate riparian species and ecosystems, and force entire communities to relocate.
An alternative tactic, used in sailing and aviation physics, yields a new approach to environmentally sustainable hydropower, the Schneider HydroengineTM. Hydraulic power is defined in terms of the river's natural kinetic energy, and is calculated like aerodynamic power in terms of density, velocity, and area.
P=1/2ApV3; (P=0.5pV3A) Where: p=mass density; V=fluid velocity; A=fluid cross-section area
The design employs hydrofoils instead of turbines, in a series of faint dams (10 ft or lower) that emulate beaver-dam networks.
