Engineers for Social Responsibility Auckland Branch June Meeting
Speakers: Warren Snow and and Jega Jegatheeson (if available)
Date and Time Thursday 17 June 2010, 7-30pm
Venue Room 3.407 School of Engineering, University of Auckland, 20 Symonds Street
Warren Snow and Jega Jegatheeson the inventor will demonstrate a model of GVT (Gyroscopic Variable Transmission) for wind wave and tidal power. GVT is an exciting new technology that has the potential to solve the huge and expensive problem of gearbox failures in wind turbines that is facing the wind power industry throughout the world. Gearbox failures are so frequent that some wind farm developers are factoring replacements at 5 – 7 years into their business models. GVT solves the problems of gearbox failures through the unique way that it transfers torque from the blades through to the generator. GVT not only protects the turbine against wind gust shocks, but also eliminates the need for expensive power electronics and enables the turbine to capture and generate more and better quality electricity. Additionally it has been estimated by wind power consultants Garrad Hassan that GVT will be about 50% the cost of existing transmissions.
Warren Snow is the Manager of Envision New Zealand, an environmental and economic development consultancy formed 10 years ago. Envision offers strategic planning, research, project management and marketing services to clients who include businesses, councils, and non profits.
Mr Jegatheeson is the inventor of GVT and GEL’s technical Director
Envision is contracted to provide management services to Gyro Energy Ltd. (GEL). GEL has an exclusive worldwide license to develop and market GVT for renewable energy applications. Warren has talked to ESR on a number of previous occasions.
