This project was based on one of Viktor's patents (British Patent # 1,187,632). It uses a original discovery of Viktor Schauberger's. The discovery was that certain shapes initiate whirlpools when a motor is attached to the bottom and made to drive a small fin in circles. He claimed a resonance effect could be achieved which decreased the needed power of the drive motor. Theses egg portions have holes where a motors shaft and housing can mount to the bowl. A plastic rotor is included in the files which is designed to attach to an electric motor of small size. An electric motor drives the plastic rotor at high speed, causing a vortex to form in an open body of water. This is ideal for use in aeration of stationary water resulting in rejuvenation. The motor's speed must initially be matched to the depth of submersion of the bowls until resonance is achieved. Both an upper and lower egg portion are included just as is referenced in the patent.
