Worlds Smallest Petrol Engine:-

Scientists have created the smallest petrol engine in the world which is less than a centimeter long and not even half an inch, small enough to power or any small gadget. The mini-motor which runs for at least two years on a single squirt of lighter fuel is set to revolutionize technology associated with it. It generates around 700 times more energy than a conventional battery. It could be used to operate laptops and mobile phones for months doing away with the need for charging.

The engine, minute enough to be balanced on a fingertip, has been produced by engineers at the university of Birmingham. Experts believe it could be phasing out batteries in such items which just six years. At present, charging an ordinary battery to deliver one unit of energy involves putting 2,000 units into it. The little engine, because energy is produced locally, is far more effective.

The main problems which faced by the engineers who have tried to produce micro motors in the past has been the levels of heat produced. The engines got so hot they burned themselves out and could not be re-used. The Birmingham team overcame this by using heat-resistant materials such as ceramic and silicon carbide.​
