This still assumes that the portal is an infinite-energy machine, though, which I think is unwarranted and creates more difficulty than is necessary. I would assume that the portal itself has no properties and does not act on other objects.
a. The portal maintains itself via energy supplied remotely by the portal gun or
b. Once created, a portal does not require energy to exist. It’s simply an anomaly in space-time. A strange loophole whereby one location is closer to another location that it’s supposed to be or
c. The portal runs on chuckle-power generated by Cave Johnson’s witticisms
I think the idea that the portal generates infinite energy is too complicating and problematic to be assumed.

How do you suppose the portal maintains itself?
