Airflow driven electrical generator for a moving vehicle
InactiveUS6857492B1Reduce resistanceImprove efficiencyAuxillary drivesWind motor supports/mountsMobile vehicleElectricity
An apparatus for generating electricity in a moving vehicle utilizes a low drag spirally shaped fin mounted longitudinally on a cylindrical component of a generator which receives air from a vent as the vehicle moves through air. The vent includes structure for bypassing at least a portion of the airflow through the vent as the vehicle moves faster through the air. The airflow causes the cylindrical member to rotate causing the generator to generate electricity. The rotating cylindrical member may be provided with magnetic material.

Electronic method of controlling propulsion and regeneration for electric, hybrid-electric and diesel-electric marine crafts, and an apparatus therefor
InactiveUS20100125383A1Easy to manufactureTracking operationHybrid vehiclesAuxillariesPropellerEngineering
A method of programming and setting parameters for a computer unit that regulates the interface between the operator of a marine vessel and the vessel's electric generation and propulsion systems. The invention describes the regulation of energy producing devices, energy storage devices and drive motors and propellers in both propulsion and regeneration modes. This invention simplifies and automates most of the operation of marine electric, hybrid electric, or diesel electric propulsion because the only controls requiring operator intervention are three generator modes: OFF, AUTO and ON, an alarm, an override switch and one or more throttle(s). This helm control can be duplicated in different areas of the vessel. All automatic modes required to regulate forward movement, reverse, emergency power, zero drag, propeller freeze and regeneration are all controlled by a logic using a combination of generator mode, the position of the throttles, the speed and the stored parameters of the vessel.

Turbine-integrated hydrofoil
InactiveUS20070046028A1Good energyFacilitates maintaining overall stability and guidanceElectrolysis componentsAuxillariesElectrolysisEngineering
A turbine integrated within a hydrofoil extracts energy from a free-flowing motive fluid. In the preferred embodiment, the turbine is of the crossflow variety with runner blades coaxial to the width of the hydrofoil. The foremost edge of the hydrofoil comprises a slot covered by a continuously adjustable gate for controlling the overall drag imposed by the turbine. The hydrofoil mounts to a sailing vessel by means of a gimbal on a structure affixed to the hull, enabling the turbine to optimally respond to changes in direction of the free-flowing motive fluid and facilitating guidance and stability of the vessel. Both axes of the gimbal have a combination of auxiliary generator and motor with a locking mechanism. Engaging the motor and locking mechanism controls the guidance and stability of the overall vessel, and the pitch of the hydrofoil. Disengaging the locking mechanism and motor permits any change in direction of the motive fluid to affect the gimbal thereby extracting energy via the auxiliary generators. To further control drag and output power over a range of flow velocities, the preferred turbine comprises a DC generator with voltage feedback controlling field excitation, coupled to a voltage and current regulating circuit that performs electrolysis of water to produce hydrogen fuel. The hydrogen fuel tank also functions as the vessel's ballast having adjustable draft depending upon its fullness. Integrated remote control simultaneously optimizes vessel guidance, velocity, drag, stability, ballast depth, and electrolysis processes.
