Harnessing the tides

The idea of harnessing tidal streams relies on the same principles as a wind-turbine, in that a rotor spins to generate electricity.

However, instead of wind driving the rotor, a tidal stream turbine uses water. Fast flowing water is found in rivers, estuaries and tidal flows and its energy can be converted by the turbine into electricity to power factories and homes.

It is predicted that this technology will provide a large proportion of the UK's energy requirements. The Swanturbines concept is lowering the cost of tidal stream energy and some very important advantages as a renewable energy:

Low cost, Low visual impact, High predictability, Small environmental footprint
