How This Works

Compressed air is already recognised as an important medium for transfer of energy in industrial processes, and is used for power tools such as air hammers, drills, wretches and others, as well as to operate air cylinders for automation, and can also be used to propel vehicles. 

LPD uses compressed air to generate electricity. The image above shows how LPD works in a rising and falling tide. 

The design is simple. A mushroom shaped dome with an open underside sits just on top of the sea or ocean. The dome is drilled into the ocean/sea floor. This makes the dome static. As the tide rises the water compresses the air which is trapped inside the dome. The air constantly rises in pressure until the force is so great the air is forced through a vent and turns a powerful generator in order to escape from the dome. This is illustrated on the left hand side of the diagram.

Because the tide rises slowly and consistently over many hours, electricity is continuously generated as more and more air is forced through the vent as it literally has nowhere else to escape. 

During the second stage of the cycle, the tide slowly falls as illustrated by the diagram image. This creates a vacuum within the dome and air is sucked into the dome via the vent in order to counteract the vacuum. 

The same amount of air which is forced out of the dome in the rising tide will enter into the dome in a decreasing tide with the same intensity. As a result the generator is continuously turning which creates an abundant source of renewable electricity. 

LPD provides a cheap, consistent delivery of electricity with limiting effects to the environment with an almost ubiquitous supply.
