Abstract

A new design of vertical axis wind turbine is disclosed based on a dome structure using dome struts as blades that work in concert to produce rotational motion. The stability and low cost of the new design allows the turbine to function in low wind speed regimes as well as high speed winds that would be encountered in off-shore wind installations. The large stresses and structural requirements of mounting large horizontal axis wind turbines, particularly off-shore, are avoided with the new system. A new energy distribution system is proposed that will capture abundant off-shore wind energy, store it aboard a generator/delivery ship in the form of Hydrogen gas, and deliver it to an existing shore based power plant to produce electricity using a conventional gas turbine. Alternatively, the Hydrogen can be used to produce methane from coal using known processes to add natural gas to pipelines in areas that would normally be consuming the material. Both applications, and the direct production of heat by the new turbines, would stabilize our national energy grid while reducing CO2 emissions.
