A machine that creates more energy than it uses is called a "free energy device". A machine that manages to create exactly as much energy as it uses qualifies as a "perpetual motion machine".
However, such devices are physical impossibilities. The laws of physics simply don't allow either case to occur.

I will add to the previous answer that the CURRENT laws of physics, as we presently understand them, do not allow us to create machines with zero energy loss.

In reactions, this is called exergonic -- a reaction that actually releases energy.

A "free lunch" or "something for nothing." Absolutely impossible to do.
