BenchmarkingSeveral sources were found that explicitly identified treadle specifications. There are many common uses of a treadle powering a mechanical system, in place of an engine or motor.
Typical power output of a reasonably fit person between the ages of 20 and 40 was claimed to 75 watts. Considered the ideal case, we expect to obtain lower power output with the minimum being greater than the 17 watts to power the current pump and UV bulb.
Concept DevelopmentMorph Chart http://www.eng.fsu.edu/~haik/design/idea_generation.htm
Pugh Chart - Power Generation, Hand Crank as Datum
Pugh Chart - Power Generation, Photovoltaic Cell as Datum
Pugh Chart - Pre Filter, Flour Cloth as Datum
This Pugh Analysis was that of filter selection. We considered, again, the current method, a flour cloth, as our datum.
Pugh Chart - Pre Filter, French Press as Datum
In the next instance, we considered the best option found in first Pugh chart, the French Press. The French Press was found to be equal with the flour cloth; however, when the French Press was selected as the datum, it was clear that the current method, the flour cloth, was the best choice.
"The Pugh Matrix (PM) is a type of Matrix Diagram that allows for the comparison of a number of design candidates leading ultimately to which best meets a set of criteria. It also permits a degree of qualitative optimization of the alternative concepts through the generation of hybrid candidates."

System Architecture: Treadle [Concept Option 1]
See below. This a basic architecture of the system, outlining many of the steps and processes of the entire procedure. In this case, the treadle is powering the pump and the UV bulb in order to kill harmful biological contaminants to make "better" water. Energy transfer from component to component is lined in blue, while the mass or material transfer is lined in orange.
System Architecture: Solar [Concept Option 2]
See below. The key difference here is that the power generation for the pump and UV bulb comes from a solar array. The color key is the same.
