Alternative Energy Winds blowing 7 mph or higher will start to generate power from Whisper Windmills. Batteries can be located from 100' up to 300' from unit, depending on the wire size used. High Voltage units produce high voltage, low current power for long distance transmission to the battery using smaller, low cost wire. A transformer is included to raise the current and lower the voltage and the diode control box converts it to DC for battery charging. Wood blades can absorb moisture and lose balance.
Whisper offers a choice of wood or carbon-fiberglass blades.
Two bladed models are standard, however, a more balanced, quieter, three bladed propeller is available. Three blades have proven to be more efficient overall. Information Water Power Generators use a small volume of water raised to high pressure by running downhill in a pipeline. Water shoots out of one to four nozzles to strike and spin a wheel at high speed turning the alternator or generator. This charges 12 or 24 volt batteries.
