Smallest Petrol Engine

Goodbye batteries?



Smallest Nanotechnology Petrol Engine

[JP Press] Scientists have built the smallest petrol engine, tiny enough to
power a watch. The mini-motor, which runs for two years on a single squirt of
lighter fuel, is set to revolutionize world technology. It produces 700 times more
energy than a conventional battery despite being less than a centimeter long -
not even half an inch. It could be used to operate laptops and mobile phones for months,
doing away with the need for recharging. 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. Dr Kyle Jiang, lead investigator from the Department of
Mechanical Engineering, said, “We are looking at an industrial revolution happening in
people’s pockets. The breakthrough is an enormous step forward. Devices which need
re-charging or new batteries are presently a problem, but in six years will be a thing of the past.”

Other applications for the engine could include medical and military uses, such as running
heart pacemakers or mini reconnaissance robots. At present, charging an ordinary battery to
deliver one unit of energy involves putting 2,000 units into it. Because energy is produced
locally, the little engine 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. Professor Graham Davies, head of the university’s
engineering school, said, “We’ve brought together all the engineering disciplines,
materials, chemical engineering, civil engineering, and mechanical engineering. What better place to
have the second industrial revolution in nano-technology than where it first took place,
in the heart of the West Midlands.”
