The main work of wind turbines is to utilize the energy of wind and convert it into electricity; stronger wind is considered good for electricity production. But the speed of wind should not be too strong because it makes turbines spin too fast and in this process it commits suicide! Why is it so? Because turbine blades get ripped off by stronger winds – excessive heat damages the alternator. Turbine tower too can't remain unaffected by the strong wind. To prevent all this damage a mechanical breaking system furling is generally used. This method prevents wind turbine from spinning too quickly by turning the blades away from the direction of the wind. Furling can be manual or automatic with same goal i.e. turning the turbine blade edges into the wind when the wind is dangerously strong and stormy. 1 Comment

We all want to live in a clean and green environment and leave this planet in a livable condition for future generations. Scientists are continuously trying to find alternative clean and green fuel for our daily use. These days we hear and read about ethanol and biobutanol as alternative fuels. Biobutanol seems to have several advantages over ethanol. New pipelines are not required for transportation of biobutanol – existing pipelines will do. Biobutanol is less corrosive compared to ethanol. Biobutanol is less prone to water contamination. Biobutanol can be used alone in internal combustion engines or it can be mixed with gasoline. Biobutanol provides more energy per gallon than ethanol. 5 Comments

Automobiles companies are on the lookout to manufacture tomorrow's car. They want to minimize the disadvantages of the today's hybrid cars and capitalize on its positive features. Mechanical and electrical engineers at DaimlerChrysler, General Motors and BMW are jointly making an effort in this direction. They want to roll out a tomorrow's car equipped with technology that shuts off the internal combustion engine on its own when the vehicle is not moving. This car will work well within the city where traffic is characterized by stop and start again. But you can safely drive this car on highways too where you can speed up and enjoy a smooth ride. This car will be 100-percent electric. "It takes the combination of hydrogen and oxygen to form water, and at the same time produce electricity," says Doanh Tran, an advanced vehicle engineer with DaimlerChrysler’s Fuel Cell Vehicles & Technologies. The exhaust pipe of the car will emit water vapor. 2 Comments
