The placement of a large number of photovoltaic modules or wind energy plants in coastal regions or on floating bodies for generation of energy is known. Seawater desalination plants can be operated using this energy to generate drinking water from seawater. A significant improvement is to produce energy and drinking water on a semi-submersible rotatably anchored island. A hollow body (1) supports a surface on which the photovoltaic modules (2) and wind converters (9) are arranged. All the units, energy stores and electricity and water lines necessary for operating the plant are arranged in the hollow body. In the centre of the ring the mounting for the anchoring (3) has a freely rotatable mounting. The island is supported by at least three floating bodies (6), which may be flooded or re-emptied (6a) to compensate for different loading of the island and to increase the stability in rough water. Motors (8) are arranged on the floating bodies permitting an automatic alignment with the sun and hence an increase in energy yield. The floating bodies and the mountings (7) thereof have a hydrodynamically favorable design and are mounted on the platform such as to be able to rotate about the vertical axis. It is possible to achieve a stable coupling of several islands by means of a suitable outline and thus to multiply the yield of energy and fresh water. The device permits the production of energy and fresh water at sea wherein the energy yield is increased by means of the free rotation. |
