Does a machine like this violate laws of thermodynamics?

  1. Sep 27, 2009 #1
    Assuming a machine such that it produces blocks of negative and positive mass from vacum, and it uses the produced positive mass to power all these procedure such that it forms a perpetrual motion machine.

    would it be theoredcally posible to do this with the positive mass produced in the procedure? assuming 100% efficiency and such.

    There is no such thing as negative mass.

    ...does that mean there is no such thing as negative energy?

    No, it doesn't.

    Asked and answered - we don't deal with perpetual motion machines here. Locked.
