Dr. Edwards' air conditioner: ROVAC update

Lindsley, E. F.
September 1983
Popular Science;Sep83, Vol. 223 Issue 3, p64
The article provides information on the revamped Rotary-Vane Air Cycle (ROVAC) invention of Thomas Edwards in Florida. It states that Edward's rotary-vane compressor produces more than 15 Btu of cooling per watt with few working parts and little mechanical friction. However, the requirement for larger air compressors and the unavailability of materials that can work without lubrication had hindered its manufacturing and marketing processes.
