13.242 EXECUTIVE SUMMARY The major puzzle pieces, regarding a Global Warming solution, have been registered patents in the US for over a century. The missing component, allowing the creation of a completely clean energy source, was a control logic strategy. A Canadian developed the required control logic from 1971 to 1999, obtaining patents in several countries. We now have at least one tool to assist in the battle against the Global Warming threat. Three century-old patents, registered in the US Patent Office, presented the design of hydraulic actuators that are more efficient than actuators currently used in modern society. These inventors understood that their actuators achieve more work than conventional actuators when allowed identical fluid inputs. The three patents are: US Patent #147,519 in the year 1874. US Patent #345,446 in the year 1886. US Patent #696,768 in the year 1901. A new development, conceived in 1971, was first filed as a patent application in 1999. This application made the step of fitting the century old knowledge into a practical solution regarding a clean energy source. The inventor was awarded patents in the USA, UK, Irish, Belgian, German, Austrian, French, Italian, Swiss and Canadian patent offices. The current patents pit the work potential of the conventional actuator against the work potential of the Diamond-Shaped Actuator. The Diamond-Shaped Actuator won, as it produces more force through identical travel. As the diamond-shaped actuator pushed the conventional actuator, the volume of fluid required by the Diamond-Shaped Actuator was forced from the conventional actuator. After the Diamond-Shaped actuator produced its own source of fluid from the conventional actuator, there was surplus work potential in the Diamond-Shaped actuator's stroke. The fundamental science was known about 150 years ago. The new developments provided a mechanical/control system, creating a machine that runs itself, while allowing extraction of the work differential. This invention is intended to add to the total effort addressing the Global Warming Threat. Unfortunately, during the 1800's, early inventors were very close; however, did not see this functional application. If they had, the world would likely be much cleaner now.
