This is amazing engineering. It probably is a very common thing for some people. But this caught my attention because I’m seeing it for the first time. I found it on scidump.
It is a water wheel that has fins overhanging by its side. When the water from the river flows against the fins, the fins are moved forward and the wheel spins. The wheel itself is actually a spiral pipe which picks up water from the outermost part of the spiral, from the same river while it is rotating. The spiral then moves inwards and sends water into a pipe at the center axis of rotation. The water is then carried to a tank located several feet from the wheel. It uses no electricity, is powered by the river and is used to transport the same water which powers it. Amazing!
