Wave Energy

In seas and oceans, there are tidal waves, with a rhythm of twelve hours, originating from the earth's moving relationship to the moon. There are also waves caused by the wind which have a rhythm of approximately six seconds.
Tidal wave energy generating stations can be built at suitable coastal locations where ener gy can be harvested from conventional types of electro-generators.

Recently, generators with blades similar to those of wind generators have been tested in tidal locations.

Since the 1980s, air turbines, using airflow caused by channelled waves, have been operating in suitable areas (i.e. the OAS-System, figure right-below).




Newer systems include ones that operate under the surface and make use of the swings in water pressure caused by waves above. They drive a lineal generator through hydraulic interface.

Floating systems do not require coastal installation: the whole ocean is a potential power source.


Wave DragonWith the "Wave Dragon" (figure left), waves cause an accumulation of water which is then channelled through a turbine.

The "sea snake", 'Pelamis' (figure right-below), convolutes in the waves on thesea snake „Pelamis" surface and drives a generator through hydraulics.

The 'Brandl Motors' are fixed to concrete stabilisers that float beneath the waves. Inside the surface floating chamber, a disc rises and falls with the waves. This transmits the motion through hydraulics to the electro ge nerators.

To see some details which innovative way Brandl Motor goes to use the wave energy, please have a look to the Brandl Generator site.
