First Claim
Patent Images
1. A hydroelectric system in a pipe containing a fluid, with a connected generator for electrical output, comprising:
- a. A casing enclosing a turbine with at least one blade and connected to at least one input and output pipe,b. A gas pressure means providing substantially continuous gas pressure to the interior of the casing through at least one gas nozzle, operative to keep the turbine blades substantially free of back-flow water.
