He is listed in &#039;&#039;[[The Worldwide List of Dissident Scientists]]&#039;&#039;.<br /> <br /> ==The air motor==<br /> The device is described as a hybrid of a three-cylinder engine with a 27-to-1 compression ratio and a rotary engine using solar and planetary gears. According to accounts of the invention, it burns no fuel and instead becomes self-running by driving its own air compressor, a claim that would place it among the class of purported &quot;free energy&quot; or perpetual-motion machines that are considered impossible under the laws of thermodynamics. These operational claims have not been independently verified.<br /> <br /> The invention is tied to U.S. Patent No. 2,982,261, &quot;Air engine,&quot; issued 2 May 1961. Sources note a discrepancy in the naming: while the device is attributed to &quot;David McClintock&quot; in the free-energy literature, the patent itself was registered under the name Cleo L. McClintock. The engine appears in compilations of free-energy and perpetual-motion devices, but no neutral technical evaluation of a working unit is documented.<br /> <br /> ==External links==<br /> * [http://www.rexresearch.com/mcclintock/mcclintock.htm David McClintock (Rex Research)]<br /> * [https://patents.google.com/patent/US2982261A/en U.S. Patent 2,982,261 &quot;Air engine&quot;]<br /> <br /> [[Category:Scientist|McClintock David]]<br /> [[Category:Worldwide List of Dissident Scientists]]</div>
