Can there be a perpetual motion engine?

    In  simplest terms, no.  A perpetual motion engine would violate either the first (energy cannot be created, only changed from one form to another) or second laws (the law of increased entropy) of thermodynamics or both. 

    Machines that extract energy from external sources are not really perpetual motion machines since they don’t produce the energy themselves.
