Abstract

An electricity generating assembly includes a first turbine having a first plurality of fan blades and a second turbine having a second plurality of fan blades. A first rotor is connected to the first turbine and rotatable with the first turbine. A second rotor is connected to the second turbine and is rotatable with the second turbine. The first and second turbines are rotatably connected to a shaft such that rotation of the first and second turbines cause rotation of the shaft, wherein the first and second turbines rotate in opposite directions.
