Sail Jet Propulsion

Regenerative power

Electric Vehicle technology in sailboats is currently limited to electric motors driving propellers. These systems can generate electricity but typically the boat needs to be sailing at > 5 knots and the power generated by the free spinning propeller is small. Most electric sailboats also incorporate a diesel generator to provide backup battery charging. We are proposing that while under sail, a scoop would be engaged to force water up through the intake to turn the water jet impeller. The electric motor could then function as a generator attached to a turbine and charge the batteries while sailing. Even when sailing in light winds (or anchored in a strong current) there should be adequate waterpower to generate a significant amount of electricity with our Sail Jet Propulsion system.
