A water turbine is a rotary machine that converts kinetic energy and potential energy of water into mechanical work.
Water turbines were developed in the 19th century and were widely used for industrial power prior to electrical grids. Now, they are mostly used for electric power generation.
Water turbines are mostly found in dams to generate electric power from water potential energy.
I made a waters turbine CAD design and make prototype with a 3D printer. I first tested the turbine by putting it at the tip of a ball point pen. At the tip of the ball point pen, the turbine rotates well. I made a video but there is no option by which I can upload the video. Later I attached a...
