Wind power and transportation

The thousands of wind turbines in the eastern valleys of Southern California are all small; hardly any of them over 30m tall, their 12m blades circling endlessly, producing a few hundred kilowatts per unit. But this is not the way of the future.

86The thousands of wind turbines in the eastern valleys of Southern California are all small; hardly any of them over 30m tall, their 12m blades circling endlessly, producing a few hundred kilowatts per unit. But this is not the way of the future. The industry is looking at building bigger and bigger wind turbines, because in the wind business, bigger is better. The biggest wind turbine in the world, with a vane length of 83.5 m and a rotor diameter of 171.2 m, is currently undergoing trials at the Fife Renewables Innovation Centre (FRIC) on the shores of the Firth of Forth in Scotland. This machine is designed to generate 7MW of electricity, enough electricity generated in a day to power 50 homes for a year. It is quite a simple equation: the amount of power generated is directly related to the swept area of the vanes. The longer the vanes, the higher the energy generated in any given wind conditions. Building bigger turbines is both more energy efficient and more cost-efficient. That’s why Samsung Heavy Industries commissioned the building of the 170m diameter test rig at FRIC. …Read More
