What is this device/class of device called, and what is so special about it?

Cracked by everyone.

Answer:

Atmos clocks – they can practically run forever since they get their “energy” from minor variations in atmospheric pressure and temperature.

    Atmos clocks
    Do not consume much energy, work on principle of expansion and contraction of ethyl chloride due to change in atmospheric temperature


  2. Rogi Says:

    Just your average barometric clock, I think.


  3. krudebox Says:

    Atmos Clock which gets the energy it needs to run from small temperature changes and atmospheric pressure changes in the environment, and can run for years without human intervention.

    Atmos clock,it gets the energy it needs to run from small temperature changes and atmospheric pressure changes in the environment, and can run for years without human intervention.

    Atmos clock by Jaeger-LeCoultre.

    Temperature variations supply the energy that drives it. ” its balance wheel will move as long as there is a sun in the sky.”

    Atmos clock – doesn’t need to be wound, can ‘potentially’ run perpetually.

    Atoms,The Perpetual Motion Clock – gets the energy from temperature and atmospheric pressure changes and can run for years


  9. poo Says:

    oops I meant Atmos..


  10. Dibyo Says:

    it is the atmos clock, which is called the ‘perpetual machine clock’ though it’s really a clock that runs on small changes in ambient temp/pressure

    I really can’t think of very much that’s *special* about atmos clocks. They have been around for several centuries. Do you mean the *perpetual motion* claim?


  12. googboog Says:

    the watch is wound by expanding and contracting gases caused by temperature changes in the air around it
    Atmos clock


  13. shrik Says:

    Atmos clocks can run practically perpetually without human intervention, as they operate thru difference in ambient air pressure and temperature.

    Atmos clock (http://en.wikipedia.org/wiki/Atmos_clock)
    It can run for years without human intervention and is sometimes called the perpetual motion clock.


  15. mankuTimma Says:

    Atmos clock manufactured by Jaeger-LeCoultre,which is powered by the changes in temp and pressure and can run forever without any human intervention. Its a kind of perpetual motion machine.

    Atmos clocks. To quote Wiki “It gets the energy it needs to run from small temperature changes and atmospheric pressure changes in the environment, and can run for years without human intervention.”


  20. dheeraj Says:

    The Atmos clock is manufactured in Switzerland by Jaeger LeCoultre(pic 1.)

    It doesn’t require batteries…or winding the spring..

    The temperature changes are used to wind the clock spring.(pic 2.)

    All contacts are virtually frictionless…

    Atmos clock that are driven by the temperature variations.
