The tail of the trout follows a wave movement where water slips in a way along the animal.
This movement is more adapted that the propeller in a water environment because it creates less friction and reduces the energy needs.
Trouts have the capacity to synchronize their speed according to vortexes’ stereotyped series. Trouts can therefore keep a stationary position against the tide while consuming very little energy or reduce, 4 to 6 times, the power needed to swim inside a shoal.These energy savings inspired Viktor Schauberger (1885-1958). By observing fish movement in torrents, movement that challenges the laws of gravity, he achieved the prototyping of implosion engines with these physical principles, that consume absolutely no fuel.
