Tudor, Michael, John, White, Neil, Maurice, Beeby, Stephen, Paul and Harris, Nicholas, Robert (Inventors) (2010) GENERATOR FOR CONVERTING FLUID ENERGY TO ELECTRICAL ENERGY. WO2010043617.
Abstract
This specification discloses a system for harvesting electrical energy from fluid flow using an oscillating mass spring structure. A mass is attached to a spring anchored to a supporting housing. The mass interacts with the fluid flow and oscillates with the spring. The oscillation is coupled to a transduction mechanism which converts some of the kinetic energy of the oscillation into electrical energy. The housing provides a means of protecting both the generator and the user. The housing also provides over-range protection and a means of controlling the interaction of the generator with the incident fluid. The object of the invention is to provide, a low manufacturing cost, reliable generator, suitable for miniaturisation which functions effectively at low wind speeds.
