No way
First: The impeller of a 300-watt wind turbine cannot be blown with a household electric fan. The impeller of a 300-watt wind turbine has a diameter of 1.8 meters and a rated wind speed of more than 5 meters per second.Motor For Air Conditional Manufacturers
Second: Use a vertical electric fan with a diameter of about 50 cm and a motor power of 100 watts. If you want to blow it with an electric fan, the power of the electric fan must be more than 1,000 kilowatts.
Third: If the diameter of the electric fan is about 80 cm. It may blow, but it consumes 1000 kilowatts. Getting 300 watts of electricity is more than worth it. Energy is conserved, and energy is lost in conversion.
