No, I don't think so. Perpetual motion machines are not "impossible" because we simply do not know how to create them; in fact we know that they are impossible because they would violate the laws of thermodynamics.

Yes I get the difference, but the deal with "no one knows what science doesn't know" is that someone could say there are exceptions we don't know about or things we overlooked, just like Newton overlooked things that Einstein discovered.
