Partner sought for lightweight superconducting generator

Development opportunity

Robert Gordon University, Scotland, has built two low-speed, wind-powered working prototypes of a lightweight superconducting generator and is looking for partners to assist with the development of application specific prototypes. Beyond initial investment, the university would be interested in a joint venture to take to market, or would consider licensing on an application-by-application basis.

The spherical design of the generator gives it a smaller volume than cylindrical designs with the same surface area. There is increased stability as rotating components are on the same neutral axis. In addition, the uniform spherical magnetic field stabilises the rotor, while uniform spherical magnetic flux increases efficiency.

A flywheel provides stability and compensates for load fluctuations, and the unit is geared without a gearbox or drive train, reducing moving parts and wear. There is direct transfer of energy from the load source, increasing efficiency.

The generator has a number of applications, in wind/gas/steam turbines, automotive micro turbines, and flywheels, electro-mechanical batteries and fluid pump or flow regulators.
