Energy Quote

We don't believe wind is the sole answer to our energy needs, but we believe wind plays a larger role that it does today.

Tidal Power

A Brief Description:

Harnessing the tides in a bay or estuary has been achieved in France (since 1966), Canada and Russia, and could be achieved in certain other areas where there is a large tidal range. The trapped water can be used to turn turbines as it is released through the tidal barrage in either direction. Worldwide tidal power technology appears to have little potential, largely due to environmental constraints. Another possible fault is that the tidal power system would generate electricity most efficiently if it were to generate electricity in bursts, every six hours (once every tide). Obviously, this limits the applications for which tidal energy can be used.

Salinity Gradient Power

A Brief Description:

Salinity Gradient is a technology that takes advantage of the osmotic pressure differences between salt and fresh water or water of different salinity. Salinity gradient power is completely renewable and sustainable. It is the highest energy concentration (i.e., energy density) of all marine renewable energy sources, an ultra-dense energy resource. Despite its potentilality, salinity gradient energy is often-overlooked source of marine renewable energy.

Wave Power

A Brief Description:

Harnessing power from ocean surface wave motion is a possibility which might yield much more energy than tides. The feasibility of this has been investigated, particularly in the UK. Generators either coupled to floating devices or turned by air displaced by waves in a hollow concrete structure would produce electricity for delivery to shore. Numerous practical problems have frustrated progress.
