I can build a perpetual-motion machine.
I can build a Dean Drive.
I can run the laws of thermodynamics in reverse.
I can conjure new matter out of nowhere.
I can go back in time or faster than light.
All without violating the known laws of physics.
I give you: Negative energy!
*Conjure* equal amounts of matter and unmatter out of nowhere!
*Zoom* off to infinity by balancing positive momentum with an equal
amount of negative momentum!
*Travel* back in time using General Relativity and wormholes!
*Dispose* of that pesky heat by transferring it to negative/positive
matter and annihilating it!
Now, what I do doubt is that there's a strictly *mechanical* workaround
for thermodynamics or conservation...
