This device was designed in SolidWorks and later 3D printed and tested as a demonstration of hydroelectric power generation techniques. A neodymium magnet was place in the inner cavity of the spinner and the external shell was wrapped in copper wire. When water flowed through the device, the magnet generated a very slight electrical pulse through the wires. Many of the components were fully assembled using acetone to fuse the components together. Two aluminum rods are necessary to support the spinner. O-ring tubing was used to seal the device.
