    Entropy Systems
    By James December 13, 2000, 09:29 PM

    I would hope that if you read this, you know what entropy is.

    Anyway, I have been following this technology for awhile now and I thought it might be nice to share the wealth. Since this is really an off topic, I won't expect too much technical discussion of the technology, but feel free to suprise me.

    This is a link to entropy systems. Entropy Systems is a company that is developing an engine that turns thermal energy (heat) into mechanical force.
    http://www.entropysystems.com/WhatisEntropyEngine.htm

    Look around the site, gather your thoughts and let me know if you find this as interesting as I do.

    Question to ponder: If the engine can run off subzero thermal energy, how do you stop it once it has started? (There will always be a supply of energy for it to use)

    All this is a little too confusing to my poor brain

    Why not build an "OFF" switch into the thing? Is that too easy? Or did I miss something???

    Well I read the page and wondered to myself what the definition of heat was. So here is all you ever wanted to know about it! (and more)


    heat
    n.


    1. Physics. A form of energy associated with the motion of atoms or molecules and capable of being transmitted through solid and fluid media by conduction, through fluid media by convection, and through empty space by radiation.
    2. The sensation or perception of such energy as warmth or hotness.
    3. An abnormally high bodily temperature, as from a fever.
    4.
    a. The condition of being hot.
    2.A degree of warmth or hotness: The burner was on low heat.
    5.
    a.The warming of a room or building by a furnace or another source of energy: The house was cheap to rent, but the heat was expensive.
    2.A furnace or other source of warmth in a room or building: The heat was on when we returned from work.
    6. A hot season; a spell of hot weather.
    7.
    a.Intensity, as of passion, emotion, color, appearance, or effect.
    2.The most intense or active stage: the heat of battle.
    3.A burning sensation in the mouth produced by spicy flavoring in food.
    8. Estrus.
    9. One of a series of efforts or attempts.
    10.
    a.Sports & Games. One round of several in a competition, such as a race.
    2.A preliminary contest held to determine finalists.
    11. Informal. Pressure; stress.
    12. Slang.
    a.An intensification of police activity in pursuing criminals.
    2.The police. Used with the.
    13. Slang. Adverse comments or hostile criticism: Heat from the press forced the senator to resign.
    14. Slang. A firearm, especially a pistol.
    n. attributive.
    Often used to modify another noun: heat barriers; heat resistance.

    Much, much more.

    In answer to blood red's question:

    The engine absorbs heat and transfers it into mechanical movement. It absorbs heat so effectively, it can absorb heat even at sub-zero temps.

    So your engine is absorbing heat. You brake the engine, and it stops. Then it starts back up again. Why? because it is always absorbing heat and transferring it to mechanical energy, even at sub-zero temps.

    So my only concern is that once the engine starts there is no way to stop it. (in theory)

    I think the real application of this would be a generator to keep a battery array charged. Link the engine to a transmission of some sort, so you can disengage the drive to the generator to prevent overcharging. Could you imagine having an electric car that you never had to plug in and recharge? Very sweet.

    A generator can be disconnected with a relay and it will quit charging. These engines would be best suited for power plants and thay rich guys balloon you know the one that keeps trying to circle the world.

    I think it's confusing for some people that Zero or sub-zero isn't zero at all.
    Zero Kelvin would be ZERO (meaning no energy)
    because at this (non-existent)temperature the molecular movement (as stated by Brown)is Zero. So anything above 0 K (not O.K. ) contains energy (kinetic energy we know as heat). Theoretically you could use this energy ( in case your energy level is lower )

    But after all. That's pure theoretical speculation. I didn't see anything to take hold of on this webpage. It's mor SF than real science.
