A much smaller Enerotor device may be mounted in a tank of water mounted on curved supports on roller bearings allowing the tank to 'rock'. As the Enerotor bobs vertically within the tank it generates waves which tilt it from side to side causing a reciprocating wave motion to be perpetuated. The waves generate different height levels on either side of the Enerotor allowing small buckets to be filled on one side and emptied on the opposite side as in the much larger sea model.
The cylinder can only rotate in one direction and the cylinder‟s attached inner ring gear drives the generator rotor around a stator on its axle moving vertically upwards and downwards within pillar slots. The rocking motion is amplified by compression springs placed at the extremes of the lower rocking supports which are alternately compressed and then release this energy in the opposite direction.
A liquid level control ensures there is always sufficient water in the tank by activating a valve for more water to be added from an inline source. If the water should steady, the controller will release a pulse of energy from a battery constantly being charged by the Enerotor to submerge a volume displacer wave initiator driven by a solenoid to initiate the wave cycle again.
