The amount of energy needed to lift it out is a lot more than that.

That is something that I didn't address, and it would be a very interesting thought experiment. A transporter/teleporter works by converting mass into energy, transporting energy, and reassembling the energy into mass again in another location.

What that involves is actually a giant change in the potential and kinetic energy that the transported mass contains. When on the surface of the neutron star, the mass has (let us assume the mass is at rest) zero potential and zero kinetic energy. When transported out of the gravity well, a bunch of kinetic energy must be added to the mass (at least enough to put it into orbit around the star) and a bunch of potential energy must be added (equal to the height of the gravity well). That is how we put an object into orbit around the earth, we add enough energy to the mass (velocity change induced though a chemical reaction) to get the mass into orbit.

If we get the energy from dropping mass on the neutron star as you suggested, and we assume a perfect energy transfer system, we need to drop an equal amount of mass onto the star as we are transporting off the star.

I think you would have a problem zapping the energy across unless you found a way to slip dimensions. The energy of that much mass would be enormous, to convert and reconvert would not have much to do with the gravity well.....

Stopping gravity from acting across a dimensional shift might be a bit of a problem though......


Also, what would happen if you did not pay your $75 Neutron Star Department fees? Would they let your house be both imploded from gravitational force, exploded from rebounding kenetic energy and vaporized by neutron emmission?

It would have to, or the energy gained by raising the mass above the surface of the star would come out of nowhere, and violate conservation of energy laws. Otherwize, you could transport some mass to orbit at 'zero energy cost' and drop it back on the star to get free energy in a type of perpetual motion machine, or free energy generator.
