The Enerotor has a different type of operation and is believed to be effective in deriving an increased efficiency despite being easy and inexpensive to manufacture and use. It consists of a revolving new wave powered motor which drives generators directly to produce green electricity.
It includes an elongated cylindrical body which is mounted in a horizontal position having regard to the prevailing disposition of wave motions. Attached to the cylinder in a variety of ways are a plurality of rows of buckets which can be very large in capacity arranged in special configurations. The buckets are adapted to receive water from the swell of a wave on one side of the cylinder and to discharge water when those buckets rotate to the other side of the cylinder. The cylinder axle may be mounted on pillars fixed to the sea bed. It is associated with many electrical generators so that the rotary motion of the cylinder around the axle is harnessed to produce electricity. Adjustable axle slots allow positioning taking advantage of predictable optimum sea levels. It may also be mounted on a floating raft, etc.
Thus the swell of a wave will cause the buckets on one side to be filled by the water on the leading edge of the swell and thereby cause rotation of the Enerotor due to imbalance of the buckets on either side. The filled buckets will move downwards through approximately 180 degrees to commence an upwards direction accompanied by the instantaneous displacement of the water by air ingress through orifices at the leading edge of the specially shaped buckets immediately releasing any vacuum build-up as they ascend on the trailing zone of the swell having passed the cylinder.
A novel feature of the Enerotor is the fact that it can only rotate in one direction irrespective of the wave conditions and directions in which it is situated. This is because the buckets can only be filled with the wider open ends upwards and this side must descend whatever direction the swell may come from. It automatically starts and continues to rotate when positioned in waves.
This permits multiple generators to be mounted within its cylinder or alongside driven by the huge rotational forces according to its capacity. Special novel configurations allow multiple generators to be utilized simultaneously each contributing to the total electricity output.
The concept of incorporating a number of planetary gears each containing electricity generating devices that could be driven simultaneously by rotating ring gears fixed to the inside of the cylinder rotating around smaller ring gears on the axle was investigated during early concept development but has been superceded by the external generator concept.
