ABSTRACT:
The Present Invention enables energy to be extracted from the atmosphere by creating a vacuum into which atmospheric air is drawn through a vacuum operated motor. The motor operates on the pressure differential between atmospheric pressure at the motor inlet and the vacuum level created by liquid flowing vertically through a tube via gravity. The greater the pressure differential, the greater the airflow through the motor, and the greater the energy extracted by the vacuum motor. The Present Invention is a workable and sustainable vacuum energy recovery system based on siphon principles, and specifically addresses problem areas immediately identifiable to a siphon-based system with air infusion. A scavenger loop operates independently to prevent air and/or gas from accumulating at the siphon apex. Micro-diffusers designed for sweeping effects across the air-liquid interfaces also provide for the optimal ratios of air volumes and bubble sizes compatible with the liquid flow rates within a given siphon. Additional flow controlling valves are not required.
