The possibility of locating wind turbines on the seabed can open up a new frontier for wind power as a significant domestic renewable energy source along the western coast of India. Space for much larger projects is available in shallow coastal waters compared to land. To assess wind power potential in the western coast of India, first the bathymetric data are divided into three regions, i.e. 0-10, 10-20 and 20-35 m respectively, suitable for fixed-bottom foundation technology. Next, the wind data of several meteorological stations are collected from WindSat satellite. For a given bathymetry, using the characteristics of wind turbine, calculations are made for estimating average wind speed, wind power density and average output of wind turbine. Results of the preliminary study show that there exists a total available area of 67,622 sq. km (up to a depth of 35 m), suitable for installation of offshore wind turbines. Further, results reveal that within the total effective area, the average annual power generation of 477 and 437 TWh respectively, could be achieved using GE 3.6s and Repower 5M commercial offshore turbines.Keywords

This paper presents the comparative details of biodiesel production process using low frequency ultrasonic energy (28-33 kHz) and conventional mechanical stirrer method. For this purpose, two different non-edible oils namely Thumba (Citrullus colocyntis) and Waste Cooking Oil (WCO) are used as the biodiesel feedstock. The experiments have been performed for molar ratio (alcohol/oil) 6:1 and 4.5:1, with three different catalyst percentages (0.5%, 0.75% and 1%) of Potassium Hydroxide. The important chemical and physical properties of (Thumba) and Waste Cooking Oil biodiesel were determined and compared with diesel. It is observed that the density and viscosity values of both the biodiesels are within the permissible limits but still higher than petroleum diesel. Further an experimental investigation has been carried out on a four cylinder, diesel engine operating on diesel and biodiesel blends [BIO, B20, and B30] of Thumba and WCO. The significant conclusions of present study are: (i) Biodiesel production through ultrasound energy seems to be a relatively simple, efficient, time saving, eco-friendly and industrially viable process, (ii) The trends for percentage variations of performance parameters for biodiesel blends (in reference to diesel as baseline) do not show any deterioration.(hi) There is tremendous improvement in smoke reduction while operating with biodiesel as compared to petroleum diesel.Keywords
