African watersupply
This is a great incentive for communities with poor water-supply to make merry-go-rounds. Kids run waterpumps by playing! Good stuff! I’m not to certain about a water-wheel, though. I imagine it hurts backs and is incredibly uncomfortable. But then again I haven’t tried a two-digit number kilos of water on my head either. Thanks to aWholeLotANothing for pointing me to them
