Abstract: The present invention relates to spiral wind turbines and an energy-harnessing system. The system features a plurality of spiral wind turbines adapted to collect drag energy of moving vehicles and for converting the collected energy into electricity. The spiral wind turbines can also be installed for collecting air flow energy from heating vents on rooftops, smokestacks or similar structures. The system uses wind energy along with captured moving air or heated air energy for producing electric power using electric generators and storing same using storage batteries. The turbines are vertically rotating, and the method of attachment/installation will depend on the type of turbine and the location. The system allows federal, state, and local governments, as well as others, to generate electricity passively.
