Low-cost household wind turbine

The invention relates to a low-cost, portable, self-aligning rooftop wind turbine designed to capture moderate-velocity wind and generate electricity efficiently for household use. Current large-scale wind turbines in South Africa are located far field and the energy generated must be transported back to communities by using huge power lines something which increases the cost of energy delivery. The portable, self-aligning low-cost wind turbine comprises a small-radius innovative blade system to ensure maximum torque per small rotating radius. It uses extremely low-cost components, is portable and can be installed with ease, as an add-on to any premises.
