With today’s afternoon, SolarWorX has a new teststand for submersible pumps. In order to not only disassemble and check all the inner components for quality, but as well run some kind of real-live test, I installed two of them directly in front of my window, so I can watch them burning in – what they hopefully will never do. The water is pumped 5 meters up and then returned in a bigger tube to let the air pass by and detroy all the nice potential energy, as we didn’t plan to build a perpetuum mobile here.
