1 Wave energy Introduction to wave energy There are several possibilities to harvest different forms of energy from the sea. One of these options is the usage of waves for the generation of electricity. The devices needed to perform this task are called wave energy converters. Wave energy is indirect solar energy in twice. At first there is the wind, which is caused by variations in atmospheric pressure due to a differential solar heating of earth's surface by the sun. Different regions of pressure drives a force which rises a movement of atmospheric air masses that causes the earths wind system. If wind strikes over the surface of an open water, waves are induced. First they are very flat with only a low level of energy. When there is a long distance over the water on which wind can attack the small ones, they became bigger and bigger with a l...
Architecture and cities in the future · The painting by Frank R. Paul · Cities made of steel, glass and plastic · Massive skyscrapers, roof-top aerodromes, wide pedestrian boulevards, metal roadways, urban space launch pads, noise regulations. · Cities must change radically to achieve long-term sustainability. · Energy, food and water sources, transportation systems and basic infrastructure, must all adapt to emerging pressures from climate change, dw...
