Sistema de Conversão de Energia Térmica Oceânica Conversão de Energia Térmica Oceânica(CETO) É um sistema de geração de energia inovadora que utiliza a diferença de temperatura ligeiramente entre a superfície da água do oceano ea camada de água do oceano profundo Xenesys Inc. adquiriu uma licença exclusiva para a patente sobre o "Uehara Cycle", um ciclo desenvolvido pela Universidade de Saga com maior eficiência que o método convencional, e está a implementar testes de demonstração com um modelo de mini-usina CETO. Este é o modelo do sistema de conversão de energia térmica oceânica desenvolvido pela Xenesys. A teoria operacional para geração de eletricidade é semelhante à energia térmica convencional ou sistema de geração de energia nuclear A turbina é gerada pelo vapor e amônia no processo é usado em vez de água. Ao utilizar amônia, a eletricidade pode ser gerada a uma temperatura muito baixa. Em primeiro lugar, uma mistura de amoníaco e água é enviado para um evaporador. Lá, a mistura é evaporada pela cor das águas superficiais do oceano vermelho da camada Qual, então, gira a turbina a vapor mista para gerar eletricidade O vapor é então misturado resfriado e condensado para líquido, por a água do mar de cor azul profundo and then once again sent to the evaporator as recycled water. Through the repition of this cycle, power can be continuously generated using only ocean water. The Ocean Thermal Energy Conversion system of course outputs zero CO2 emissions and can provide a stable annual supply of electricity because it is not affected by weather variations as is the case with wind power and solar power generation systems. The OTEC system demonstrates significant potential as an ultimate power supply system for the future. The Portuguese government have inaugurated the worlds first wave power station, three miles off the coast of Agucadoura near Porto. At the heart of the Agucadoura wave farm are three Pelamis wave energy converters that will generate up to 2.25MW of electricity, enough for the annual needs of about 1,500 family homes. Each of the semi-submerged, 142m long Pelamis devices, has a diameter of 3.5m and is made from 700 tonnes of carbon steel A single device is composed of four articulated sections that move up and down as the waves pass along it. At each of the hinges between the sections, hydraulic rams use the wave motion to drive generators to produce up to 750KW of power at peak output. The electricity generated by the three Pelamis devices will be carried by undersea cable to a substation in Agucadoura, which will then feed the power into the Portuguese national grid. The water of the oceans of the world is almost always in motion. Hardly ever interrupted, waves break at the coastlines, sometimes strong, sometimes weaker. There is an enormous energy potential that is available round the clock and free of charge. A potential, that if fully exploited could satisfy 40% of the worldwide demand for power. This equals the output of 700 to 800 nuclear power stations. Voith Hydro Wave Channel is developing technologies to convert this inexhaustible energy into electric power, without the emission of harmful greenhouse gases. The operating principle of this wave power station is as simple as it is ingenious. An enclosed chamber has an opening beneath sealevel, which allows water to flow from the sea to the chamber and back. The water level in the chamber rises and falls with the rythm of the waves, and air is forced forwards and backwards through the turbine, connected to an upper opening in the chamber. As it is compressed and decompressed, the airflow has sufficient power to drive the Wells turbine. It is a feature of the Wells turbine, named after it's inventor, that it is driven in the same direction by both forward and reverse airflow through the turbine. Even relatively low wave motions can generate enough airflow to keep the turbine moving, and to generate energy. This is how easily energy can be generated with a wave power station. Day and night, all year round, as long as there are waves. The world's first power station of this kind was put in service as early as November 2000 On the scottish island of Islay, and has been feeding power to the grid ever since. -10 miles off the coast- -Windfarm layout-

An often debated topic by those who don't think The Venus Project will work is the notion that we don't have the technology to pull this off. This video addresses this. If you want the full uncut version, let me know.
