New Technology? Or Old?

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 centimetre 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 peoples’ pockets. The breakthrough is an enormous step forward. Devices which need re- charging or new batteries are 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. 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. 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 the first took place, in the heart of the West Midlands.

it's better to post a link to an article, rather than pasting the whole thing into the forum.

Sorry FE, but I got it in an e-mail, couldn't think of a way to post it from that other than this. I suppose there is a way of course but my thinking box is on the blink, I think.

From 2003
Looks lie his prediction was out then or have they been on sale for the last 2 years and I never noticed.

I bought one a couple of years ago, put it down in the garage and I'm still trying to find it.
