>>But the conservation laws, like conservation of energy, of momentum, and of electrical charge, seem to be amongst the most fundamental laws, and it is unlikely (but of course, not possible to rule out completely), that they will be broken.

I don't think so. I think that in an expanding Universe, while photons (or any expanding matter, for that matter) lose energy, they would gain potential energy, just like in classical physics.
On the other hand, be that as it may, even if the law of conservation of energy might, indeed, be broken on a large scale (which I still doubt), I don't think that can be reproduced at a small scale, to make a perpetuum mobile.
