Abstract: A vehicle mounted wind powered generator has a self-contained housing with an open, forward airflow intake section and a rear airflow exhaust section. The housing is configured to be mounted on the roof of a vehicle by conventional mounting supports. Airflow is directed into the housing where it is constricted in order to increase the airflow velocity past one or more wind turbines. The airflow is then directed through a channel within the housing and is ultimately discharged through the exhaust section. Power generated by the wind turbines is used to create electricity by means of an attached electricity-generating device, e.g. an alternator/generator. The electricity produced operates a hydrogen production system having its components located within the housing of the hydrogen generator. The resultant hydrogen gas is directed to the engine of the vehicle to increase its efficiency and reduce its emissions.
