A new project off the south coast of England is using ocean currents to generate electricity.
As water is much denser than air these turbines are claimed to be 4x times more efficient than traditional windmills.
Once built these inconspicuous turbines do not release carbon dioxide or other pollution, can deliver energy to a predictable timetable + help countries to produce renewable energy in line with the Kyoto Protocol and "Agenda 21".
Potential disadvantages, at least for marine life, include impacts with the front edge of the turbine blade and/or pressure changes associated with the movement of the turbine blades, known as cavitations.
A similar system is being developed in the East River of New York, and Earth-Info.Net expects to see many exciting developments in this promising technology over the years to come...
