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. (more…)
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. (more…)

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. (more…)

Consider a technology that not only keeps your surroundings clean it also produces renewable energy at a low cost. Wheelabrator Technologies Inc., a U.S. pioneer for municipal waste-to-energy technology, wants to make sure that your waste doesn’t go waste. Literally. Wheelabrator’s waste-to-energy facilities produce steam and electricity by burning large quantities of municipal trash and they have been using this proven and time-tested mass-burn technology to produce energy for the past 100 years!

Barack Obama has been elected as the 44th President of the USA and with his election, Solar Integrated Technologies rose by 30% yesterday after increases of 22% by Renewable Energy Corporation and 16% by the wind turbine maker Vestas. Barack Obama promised to spend $150 billion over the next 10 years developing alternative energy. Promises like these leave a legacy for future generations to imitate. Clean technology and green energy stocks have registered a new high as City analysts anticipate a major boost from the incoming president. The US election result has provided a much-needed encouragement at a critical time and that too for an industry which is still in its nascent phase. And this sector is threatened by the banking crisis and emerging economic recession. Some companies had seen their share prices halve in the turmoil that began in September. Reduction of carbon level, a cushion against fluctuating oil prices and creation of more jobs in economic slowdown would be the natural offshoots of this policy. (more…)

Although the idea of driving a hybrid vehicle (and getting a better car insurance rate for doing it) has become increasingly common for the automotive public, designers are still hotly contesting the best form “alternative” fuels should take and happily experimenting with everything from electrical and hydrogen-powered cars to those that run on compressed air or draw power from solar cells. With the venerable Toyota Prius now an everyday sight on American streets, the two most productive areas of improvement for currently available and soon-to-be introduced models can be found in battery tech and the changed view of driving underlying the interest in plug-ins.
