PME recently donated a miniDOT loggerto a non-profit organization in Australia, CUSP, as a a part of their World Aquaponics Project, to record valuable oxygen concentrations. This organization is interested in developing a human power
ed system for sustainable food sources. The system was run at full capacity for a few months to test oxygen demand and trialed a number of human powered approaches to oxygenating the water, including a bike powered rope and washer pump. More information.
