Use Kid Energy to Pump Water
We used to have one of these merry-go-rounds on our playground when I taught elementary school. The insurance agent made the school remove it, because it went too fast. Just think, we could have been pumping water from the school well with all that kid energy!
Playpumps International provides “innovative, sustainable, patented water pumps powered by children at play. Installed near schools, the PlayPump system doubles as a water pump and a merry-go-round for children.”
