  • Monocoque turbo-generator
    Patent number: 7472549
    Abstract: A monocoque turbo-generator device is provided that is capable of cooling and lubricating itself and providing a non-leaking magnetic drive system that maintains the leak proof integrity of the device. This may be accomplished using propellant gases of the turbine as they process through the monocoque chamber. The monocoque turbo-generator device may produce electricity within an enclosed leak proof capsule with accessories that allow the energy to be tapped from the outside of its monocoque casing.

  • Tidal generator system and method
    Patent number: 7078827
    Abstract: A tidal generator system is provided that includes a containment tank, and a ring mechanism provided about the containment tank to rise and fall based on tidal actions. A valve mechanism allows a liquid to pass into the containment tank. Additionally, a turbine/generator system generates electrical energy based on the liquid passing through the valve mechanism.

  • Apparatus and method for generating electrical energy
    Patent number: 7013645
    Abstract: An energy producing apparatus and method are provided to harness thermal energy from a down hole resource (such as oil or gas) on an offshore rig and to generate electrical power from the thermal energy. This may include a pipe to receive either the high temperature gas or oil and a power module coupled to the pipe to convert thermal energy from the received oil or gas to electrical power.
