Oceans & the Infinite Energy Source? by Milota Sidorova

In a chase to find the alternative ways of enivornment friendly energy, the water element remains to hold the position of neverending, unfailing energy source. Not only the river, lake water power stations, but the ocean's power challenges the scientists all over the world. Lately a lot of discussions caused the world's famous and the most powerful stream & the Gulf's Stream.Starting in the Carribean sea, passing the shore of Florida, flowing all across the Atlantic ocean,and finally warming the shores of Western Europe.30 miles wide stream reaches Florida closer than any other major lands and specify the potential location of scout ocean energy projects. The researchers declares that the source could produce as much energy as perhaps 10 nuclear plants, that equals one third of Florida's electricity demand.Despite of optimistic prophecies, The scientists are not able to predict the risks of running huge underwater blades. The ocean floor stability, the blades choping up sea fauna, the possible navigation difficulties, causing potential vessel's crahes, the objective safety, the high initial costs of the buoys, that are only few points figuring the black list. "We understand that there are environmental trade-offs, and we need to start looking to alternative energy and everything should be on the table," he said. "But what are the environmental consequences? We just don't know that yet." says David  White of the Ocean Conservancy. He claimed that all the theories are in the very beginning, that no one can say what the consequences would be. For the Stream research the university cashed $5 million research grant from the state, hoping to create optimalized technology, that could be sold out for big energetic companies.The initial project says about 10-buoy wave park moored to the ocean floor, with the bouys flowing in the effective depth of 30 & 40 feet below the surface.Getting a short review through the history of water energy engineering, one must mention the fail of $2 million buoy, that sank near Oregon's cost or setback of small test project using turbines by currents in New York City's East River. The project negotiations also cross the fears of  local fishmen and crab producing companies, that have limited shore area to operate.Along with the stream energy, many research approved the companies to use wave-energy as an infinital source. For example canadian Finavera Renewables hopes to break through with 35-ton buys transferring the energy from the rising water. Each of four buoys could cover more than 700 households electricity need.
