Patent

CA 2674142

A dual-powered airflow generator comprising: a primary fan motor powered from a primary power source and an auxiliary fan motor powered from a secondary power source. In one embodiment, the primary fan motor has a first drive shaft wherein operation of the primary fan motor causes a desired airflow at a design power of the primary power source. In a preferred embodiment, the auxiliary fan motor is powered from a secondary power source and has a second drive shaft mechanically coupled to the primary fan motor, wherein the auxiliary fan motor is configured to assist the primary fan motor in causing the desired airflow while the primary fan motor operates from the primary power source at a reduced power. In a preferred embodiment, the auxiliary fan motor is powered by a solar power generating device or other alternative energy source.
