Here's the full title: 

Operating Principles, Common Questions, and Performance Data for an Atmospheric Driven Atmos Clock, by David Moline and John Wagner (both of Clemson University) January/February 2015 issue, Vol. 57/1 No. 413 of Watch & Clock Bulletin, Journal of the National Association of Watch & Clock Collectors, at www.nawcc.org

The article abstract reads:

"The elegance of the Atmos Clock and the curiosity of mankind in self-operational mechanical systems have propelled this time device into our collective desire for more knowledge. The search for a self-winding timepiece, based on normal atmospheric fluctuations, was pursued for centuries by horologists with the well-known clock proposed by J.L. Reuters and commercialized by Jaeger LeCoultre. This clock has generated numerous discussions throughout the years as noted in past Watch & Clock Bulletin articles and other correspondence within the timekeeping community. In this article, the operating principles of the Atmos clock are reviewed using fundamental science and engineering principles. Key questions and experimental observations are discussed in light of the operating principles to clarify the clock's performance. Finally, an extensive database that was gathered through physical measurements and data recording of an Atmos 540 clock is introduced." 

Fourteen pages, with illustrations, tables, specifications and formulae.

What the engineers are saying is:

People have been trying for hundreds of years to make a perpetual motion clock; there's been lots of discussion about the Atmos and its performance. We (both engineering professors) got some clocks and analyzed them to learn for ourselves.

I encourage you to find the article and read it.

Cheers,
