Abstract:

A staggered multi-level vertical axis wind turbine includes a cage structure including wind directing elements arranged circumferentially about outer edges thereof. Within the cage structure is a rotor including a centrally located shaft orientated along an axis and extending at least from one end of the cage structured to another end. The rotor includes a first rotor level of torque generating elements of a first type coupled to the shaft. The rotor includes a second rotor level of torque generating elements of a second type coupled to the shaft. The rotor includes a third rotor level including torque generating elements of the first type coupled to the shaft. The wind directing elements receive and re-direct wind onto the torque generating elements of the various levels, thereby producing torque and causing the rotor to spin. The rotor is coupled to an electrical generator, which generates clean and renewable energy.
