Gorlov helical turbine

Summary
The Gorlov helical turbine (GHT) is a water turbine evolved from the Darrieus turbine design by altering it to have helical blades/foils. Water turbines take kinetic energy and translates it into electricity. It was patented in a series of patents from September 19, 1995 to July 3, 2001 and won 2001 ASME Thomas A. Edison. GHT was invented by Alexander M. Gorlov, professor of Northeastern University. The physical principles of the GHT work are the same as for its main prototype, the Darrieus turbine, and for the family of similar vertical axis wind turbines which includes also Turby wind turbine, aerotecture turbine, Quietrevolution wind turbine, etc. GHT, Turby and Quietrevolution solved pulsatory torque issues by using the helical twist of the blades. The helical turbine (Germany patent DE2948060A1, 1979) was originally invented by Ulrich Stampa (Bremen, Germany), engineer, author and inventor. Fluid performance The term "foil" is used to describe the shape of the blade
