Guide Voice: Engines - noisy, dirty and big.

Not necessarily!

At the UK's University of Birmingham engineers have developed tiny engines, only a few millimetres wide, that could well replace a standard battery.

00:23 (SOT): Dr Michael Ward, Senior Lecturer in Microsystems Engineering at the University of Birmingham - "We've designed this engine to be a replacement for conventional batteries. Most of the products that we deal with these days are man portable and we all have to slot in our AA batteries which require changing and manufacturing. Much better if we could use hydrocarbon energy directly, much like a cigarette lighter, so that we could use these little engines to run off cigarette lighter fuel and give us electricity directly, without having to go through the battery cycle".

Guide Voice: Lead by Dr Kyle Jiang, Investigators at Birmingham's School of Engineering are the first to manufacture these engines in a durable, heat resistant material such as ceramic or silicon carbide. Laboratories like these will be the engineering plants of the future, producing micro-engines that have over 300 times more energy than an ordinary battery and are much lighter and smaller. These new power-supplying machines could soon be used to charge mobile phones and lap top computers in a matter of seconds, eliminating the need to recharge them frequently.

01:27 (SOT): Dr Michael Ward - "You have to put in something like two thousand units of energy to make a battery and yet you'll only ever recover one unit of energy when you're charging it and discharging it. So if our little engines can work within that frame, we could be a thousand times better off".

Guide Voice: Micro-engines have a wide range of potential applications - they could be used during military operations for driving micro air vehicles and micro-robots for reconnaissance purposes; communications relays; micro-cameras and other sensor carriers. Other applications will include micro-factories - tiny 'labs-on-a-chip' that will be able to make drugs, chemicals or small mechanical components.

02:07 (SOT): Dr Michael Ward - "This technology has got a tremendous future. If we just concentrate on this project, micro engine at the moment, we can see that it's going to impact a whole variety of commercial electronic products - mobile phones, MP3 players, all will become more energy efficient, have longer operating lifetimes, generally be much more convenient to use. The impact that we're going to see from micro engineering in a more general way is going to be even bigger. We have the ubiquitous silicone chip that we see in virtually everything. You're going to see micro engineering everywhere because now, with this technology, we're giving the silicon chip its eyes, its ears, it - the ability to generate power, dispense drugs - a very big future for this technology".

02:56 (SOT): Professor Graham Davies, Head of the School of Engineering, University of Birmingham - "At the University of Birmingham we've actually pioneered the whole area of inter-disciplinarity in the school of engineering. We've brought together all the engineering disciplines, both materials, chemical engineering, civil engineering, mechanical engineering, all together, to work in an inter-disciplinary fashion. And that's where we're beginning to see the fruits of that. And we've extended it much further than that, as part of the new school of engineering at Birmingham. Er we've encouraged working with the school of medicine, with the school of bio sciences, with chemis.. chemical sciences and, and with physics. And I think we're beginning to see the er, the rewards from, from that early investment in inter-disciplinarity. And also, 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 in Birmingham itself."
