direction of the water flow in relation to the pipe. They also changed the location so that the water outlet had a drop of 2.2 m instead of 0.9 m. According to connell, this height of 2.2 m allows the power to be multiplied by 3.5. Finally they decided to use the computer fan, which produces more revolutions. The 3d printed wheel also works well, but produces more torque and fewer revolutions. To achieve higher voltage, it is better to use a rotor that is capable of producing more revolutions. After starting the flow of water through the pipe, connell and his colleagues were able to see that the system was working as expected. How does it work.
The core of the system is a wheel and the motor of a hoverboard. What look like 110mm pvc pipes connect into a u shape that can be mounted on the wall of an artificial canal. The inlet side is shorter than the outlet, and UK Phone Numberthe system must be filled with water for it to start flowing, like a siphon. The first two versions had the impeller at the end of the outlet tube. The v1 used a scrap plastic radial impeller of unknown origin, and it didn't work at all. V2 had a 3d printed impeller that worked quite well, but the rotation speed was not high enough to produce the voltage daniel wanted.
Used a large computer fan that was mounted on the short horizontal section of tubing at the top of the system. It worked spectacularly well, producing about 55v ac over a single phase of the motor, which should hopefully end up producing about 90v dc and 200-500w after rectifying the motor's three-phase output. However, this is only indicative, we would very much like to see it tested with different loads connected. The output will also depend on the flow rate and head pressure of a particular stream/canal/river, and daniel admits they had more or less ideal conditions for their tests.
