How Do Wind Turbines Work?

Wind turbines generate electricity from moving winds. You can see them in large numbers on wind farms both onshore and offshore. The blowing wind turns their blades, and rotates the shaft on which the blades are mounted. The shaft in turn, operates an electric generator and the resulting electric output is sometimes stored in a battery. A swarm of wind turbines can generate a substantial amount of energy. Wind turbines are often called a renewable source of energy, as they generate power from natural Read more [...]

Can Electrocution Really Kill You?

Although cartoons tend to show a person being fried due to electrocution as the body flashes like fireworks with the bones visible to everyone, in reality, things do not work that way. Electricity does not actually fry you – unless you are struck by a thunderbolt. However, only a frighteningly miniscule amount of electricity is enough to snuff out your life. At the beginning, it is necessary to get some facts clear. Some major units used by electrical engineers are – volts, amperes, watts, Read more [...]

Wing Waves Can Generate Electricity

Scientists around the world are working to perfect technology for generating cost effective electricity from oceans and seas using wings waves. Stephen Wood, an assistant professor of marine and environment systems at the College of Engineering of Florida Institute of Technology is building up on the expertise available to exploit it in a more efficient way. A set of wing waves, also called sea fans comprise two metal structures shaped like wings. The fans are installed on the floor of the sea. Read more [...]
