Singh, a doctoral graduate of Kansas State University. I am actively engaged as a consulting scientist at R& D division of lntellimeter Canada lnc. I have 30+ years of experience with multi-national companies in Canada in the area of engineering, product development, and lTU standards. I am writing this letter Of support, regarding an invention developed by Mr. David Strain, who has patents granted in Europe, the USA and Canada. Mr. Strain has a document from Mr. Ed Komadowski, SIEMENS Building Technologies, which confirms the performance of his control circuitry. Mr. Strain brought a model to our facility and demonstrated the efficiency advantage of the diamond-shaped actuator. The load was measured with certified scales. The objective was to develop a perpetual machine. During the demonstration, the internal pressure was raised to 65" WG lifting the load and then dropped to 54" WG causing the load to fall. During the fall, the pressure was switched to 60" WG. The diamond-shaped actuator stopped the fall of the fifty-nine and threequarter pound load and lifted it upward with 60" WG pressure. A conventional cylindrical actuator holding the same elevation with identical fluid volume requires a pressure of 69.013" WG, just holding equilibrium. This demonstrated an efficiency advantage greater than 15°/o favoring the diamondshaped actuator over a conventional actuator. The force/travel relationship is non-linear; therefore, readings vary depending on the percentage of stroke achieved when readings are taken. 13.278
