How engines work?

Have you ever opened the hood of your car and wondered what was going on in there? A car engine can look like a big confusing jumble of metal, tubes and wires to the uninitiated. You might want to know what's going on in there simply out of curiosity. After all, you ride in your car every day -- wouldn't it be nice to know how it works? Or maybe you are tired of going to the mechanic and hearing things that are totally meaningless to you and then paying a hefty sum for whatever that stuff means. Or perhaps you are buying a new car, and you hear funny words like "2.5 liter 150bhp/5500rpm" and "dual overhead cams" and "tuned port fuel injection." What does all of that mean? more on  this>>

What is a fuel cell?

A fuel cell is an electrochemical energy conversion device that converts hydrogen and oxygen into water, producing electricity and heat in the process. It is very much like a battery that can be recharged while you are drawing power from it. Instead of recharging using electricity, however, a fuel cell uses hydrogen and oxygen.

The fuel cell will compete with many other types of energy conversion devices, including the gas turbine in your city's power plant, the gasoline engine in your car and the battery in your laptop. Combustion engines like the turbine and the gasoline engine burn fuels and use the pressure created by the expansion of the gases to do mechanical work. Batteries store electrical energy by converting it into chemical energy, which can be converted back into electrical energy when needed....more info>>
