A forced-air electric generator apparatus includes a housing positioned to receive forced-air flow from a forced-air device. A bladed rotor carried by the housing is in fluid communication with the forced air flow. A clutch engages the bladed rotor to drive a generator to produce a generated voltage when the bladed rotor is rotating above a threshold rotational velocity.
