  1. SMALLEST PETROL ENGINE

    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.

  2. the phone is a Nokia Lumia 920 with windows phone 8 or WP 8 is. Uses internet explorer .033_scratching_head.gif.b541836ec2811b6655a8e435f4c1b53a.gif

    aha worked it out 012_thumb_up.gif.cb3bc51429685855e5e23c55d661406e.gif needed to tap the smilies button again once I had selected one to go back to the message again.059_whistling.gif.a3aa33bf4e30705b1ad8038eaab5a8f6.gif just needed to be the bit more patient with it, I'm new to Windows 8 as well 101_thank_you.gif.0bf9113ab8c9fe9c7ebb42709fda3359.gif..

     

     

  3. It should let you add smilies...my Samsung Galaxy and my iPad does...unfortunately I can't test every smart phone, would be good fun though.What operating system and browser is on the phone...is it Android and Chrome and if so do you know what versions?

  4. Thanks for that, no big deal, just thought you would like to know. You get used to it on the PC so when you are using the smartphone it's too much like exercise to do all that swiping.

     

    it also doesn't let me add smilies.

     

     

  5. Thank You all for the warm welcome.

     

    So far I've been training in a Foxbat, a great plane to learn in. I would like get endorsements in all the other planes available at the school before I'm finished my training, namely the Texan, a Storm, a Sirius and of course the Thruster (that will be fun learning a tail dragger).

     

    One of my goals is to fly an Amphibian, as it multiplies the number of landing strips by heaps -(except for seq-water dams) and of course I would like to have one of my own too. Maybe a dream but it's something to aim at.

     

    Thanks again.

     

    Cheers
