ENERGY-EFFICIENT AND ENVIRONMENTALLY HELPFUL POWER CONVERSION SYSTEM AND METHOD
A high-efficiency energy conversion system (10) and method which is able to use a low volume air flow source such as a vacuum cleaner to turn a drive means and generate rotary energy. The system and method includes a water-filled container (16) and a drive means which is selectively made more or less buoyant at various points of rotation. The system includes leverage arms (30, 31) and balloon elements (40, 41). It may be made of smaller components for domestic use or larger components for an industrial-type usage.
