Roof-top wind turbines

VAWT - An alternative energy resource

The research team of BES has designed and patented a vertical axis wind turbine design for stand-alone applications. The helical structure of the designed blade geometry enables uniform torque distribution, thereby reducing the vibrations during operation. The CFD experimentation on the turbine proves the turbine to be self-starting at low wind velocity.

The turbine still needs to be experimented with a laboratory scale prototype before being launched.
