GIANT SEA SNAKE ( PELAMIS )
A Renewable Energy Application
Abstract:
Over the last few year’s development associated with low or even zero based greenhouse gas emitting energy sources is on it’s peak. More recently volatility in the price of oil and gas has increased the number of problems of low greenhouse gas emitting energy sources. Our paper mainly concern’s in this aspect to produce electricity with the lowest p/kWh with no-fuel and delivers power at round the clock without any pollution at 88% efficiency with 750Kw rated value . Hence we go for Ocean energy with Gaint Sea Snake - ( Pelamis Wave Energy Converter).
About Wave Energy:
Wave energy is a concentrated form of solar energy: the Sun produces temperature differences across the globe, causing winds that blow over the ocean surface. These cause ripples, which grow into swells. Such waves can then travel thousands of miles with virtually no loss of energy. Don’t confuse these deepwater waves with the waves you see breaking onthe beach. When a wave reaches shallow water (roughly when the depth of the water is less than half a wavelength), it slows down, its wavelength decreases and it grows in height, which leads to breaking. The major losses of energy are through breaking and through friction with the seabed, so only a fraction of the resource reaches the shore.A wave carries both kinetic and gravitational potential energy. The total energy of a wave depends on two factors: its height H and its period T.The power carried by the wave is proportional to H*H and to T, and is usually given in watt per meter of incident wave front.
P=(H)square*(T)/2 KW/m.
Pelamis Wave Power Ltd : Pelamis Wave Power (www.pelamiswave.com) has been developing the Pelamis technology for the past 10 years, Headquartered in Edinburgh,Scotland. The prototype for the Portuguese machines was launched in February 2004 and first supplied electricity to
