The scientists have created the smallest petrol engine in the world (less than a centimeter long not even half an inch),small enough to power a watch or any small gadget.The mini-motor which runs for two years on a single squirt of lighter fuel is set to revolutionize technology associated with it. It generates 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.Experts believe it could be phasing out batteries in such items within just six years. The engine, minute enough to be balanced on a fingertip, has been produced by engineers at the University of Birmingham. 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.
One of the main problems faced by 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, finally.

I want one, where can I get one?
this is just dumb, making ne winventions on resources that are ending.. nice way to rise the prices, it will be awesome people getting in line to pay overprices petrol so they can continue doing their jobs to get $$ to buy more petrol.
Unbelievable....Amazing engineering
World's ugliest fingernail?
this uses alot less energy to create energy vs a battery. This saves on resources if what they're saying is true.
Interesting, but devices with moving parts are usually less reliable then solid state devices. I'm sure it will have its uses. Only time will tell where this technology will end up.
How would they handle Exhaust Gas?
Just what I need for my cucaracha micro mini car
It must be a very very tiny stirling engine... If properly crafted they last for years without service, NASA is using a Stirling engine (manufactured by Sunpower Inc), a normal engine lasts for about 15 years without service... so this little thing should be reliable for at the very least 5 years.
