| 1183183 | 2011-03-03 08:07:00 | Will we hear of this again? 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 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. |

| 1183189 | 2011-03-03 20:12:00 | Think of the ancillary technologies this little gizmo will spawn. Being an internal combustion engine, it will no doubt need to have an oxygen supply, so in the case where it powers a pacemaker, it would need a supply from say a lung, with all the appropriate valves and timing gear. Then there's the exhaust gases to eliminate with a further connection to, well ... That would possibly need a silencer, in several models ranging from 0Db to 100Db Boy Racer. The possibilities are endless. You read about them here. :lol: |

| 1183190 | 2011-03-04 05:15:00 | From the description: "At present, charging an ordinary battery to deliver one unit of energy involves putting 2,000 units into it." Li-Ion batteries are actually quite efficient, pump 1000mAh into them, and you'll get almost 1000mAh back out Anyway, how reliable are they? If they break down like your car, I imagine they'd be pretty tricky to fix :D |
