    Could we harness energy from Earth movement relative to physical vacuum?
    Earth is moving around Sun with speed of 30 km/sec.
    Also there exist force of Casimir and similar effects.
    If we have some body (for example a ball) which is moving in some media
    (for example water) then to harness energy from such movement we need
    to build a turbine on the ball wich would be able to interact with water and
    rotate around its own axle.
    What could be such analog of a turbine which would be able to interact with
    physical vacuum?

    No it would not be possible to do this; and if it were it would result in a loss of kinetic energy, i.e. a slow-down, and therefore a change in orbit of the earth. Definitely not recommended.
    The Casimir effect is a quantum mechanical effect and has no bearing on the earth's movement in its orbit, and neither does vacuum energy in general.

    by definition a vacuum is the absence of matter-what are you going to harness?

    Possibly you are jocking.The kinetic energy of the Earth is so huge, that if humanity will satisfy all its current energy needs with
    help of this energy harnessing then maybe year will become longer on one second in one million years!

    What do you think on dynamic Casimir effect?First Observation of the Dynamical Casimir Effect - Technology Review
    All we need is some particles or force fields that will interact with physical vacuum at ambient speeds.

    Actually, the year would become shorter as the earth spiraled in...

    And again, there's nothing to interact with in a vacuum, so nothing to exctract energy from.

    Is this true there is such thing as polarization of vacuum?That any free charge gets surrounded with virtual
    particles of opposite sign?If so, could be there some interaction?

    There is a theory which reagards vacuum as a superfluid.

    The SVT model is just an ( admittedly interesting ) approach to formulate a theory of quantum gravity - there is currently no experimental evidence in support of this model. I am not quite sure how this is even relevant to this thread.

    Vacuum polarization is a real physical effect that has been experimentally observed in the late 1990s ( if I remember correctly, don't quote me on this ). However, it is an effect in the presence of an electromagnetic background field, weakening the field due to the presence of virtual particles. I see no way to use this effect to generate any form of energy ?

    Quite generally speaking, according to current physical principles it isn't actually possible to "extract" vacuum energy, and no device has ever been built that was able to do so under controlled, repeatable circumstances ( correct if I'm wrong, I'd surely like to know about it !! ).

    If we have a charge surrounded by virtual particles of opposite charge,doesn`t it means that moving charge should experience some kind of pressure?Is it like flowing in opposing medium?

    We are talking a 3-dimensional volume of space, so any forces exerted by virtual particles will act equally from all sides, meaning the net effect is zero. No such forces have been experimentally observed in unperturbed, free vacuum.

    yeah you can harness energy from earth rotation witha powerball



    the efects of this would be a slowing of earths rotation and the acleration of the rest of the universe due to conservation of momentum

    Are you going to tell that such powerball never stops without human
    involvment and even generate netto energy?

    eventually will stop when erath momentum is over

    Or rather when you stop rotating it with your hand...

    i dont know about the engineering

    i just happen to notice earth would spin that thing as hand would do

    anyway i kind of regret my post

    this would be bad bad idea

    1)Scientists claimed that they observed a dynamic Casimir effect under which a body which moves with acceleration
    should create real photons out of physicsl vacuum.
    First Observation of the Dynamical Casimir Effect - Technology Review
    Earth globe rotation is claimed to create Coriolis force which is also associated with acceleration.
    Coriolis effect - Wikipedia, the free encyclopedia
    Does it mean that Earth rotation is able to produce dynamic Casimir effect?

    2)It seems there is way to get net energy from Earth rotation because Coriolis force is
    claimed be able to produce some Ocean currents or at least to make them stronger.
    If we are able to harness marine currents energy it should means we harness energy
    of Earth rotation too?The only problem is that it is quite small and means small power
    density.Could we make Foucault pendulum to generate some energy?If we will add some
    dynamo machine to it,well be it able to light some small lamp?

    no the hand is earth
    Could we make a hyroscope in a way that it would react not only on number of full rotations per day
    but also on absolute speed of rotation (around the axe)?Earth rotation is quite slow, one rotation per
    24 hour, but absolute speed is quite high - more than 100 meters a second.Meybe some gearing could
    help?
