Does a machine like this violate laws of thermodynamics?

[そらの日記]

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.

There is no such thing as negative mass.

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

No, it doesn't.
