profitis, just because something is possible in theory, does not mean it's practical or desirable, especially when working on a nanoscale.
Dr.Daniel Sheehan http://www.sandiego.edu/cas/about_the_college/faculty/biography.php?ID=485 has demonstrated (as far as I am concerned) that LoT2 can be broken; he is not confident that a practical device can be made.

Well @markE I did provide a textbook-compatible statement that you could not physicaly or theoretically disprove,AND you`re a scientist.that says alot.I had wanted to join forces with mr hardcastle a few years back but he was on his own mission.I don't hold that against him. there is a certain respect between all demonologists.how do you know for sure that none of his claims were realised?it may be in his interests to fade from the limelight with you and me thinking he,s got zip.we just don't know what's going on behind the scenes.all we know is that on this thread,no proof was given.

Whatever "textbook-compatible" is supposed to mean.  You promised over and over again that you could provide an actual citation and failed to do so.  Mr. Hardcastle has been unable to prove any of his 2nd Law violation claims.  I am sure that he would be delighted if you or anyone else could prove one of his claims for him.

If a 2lot violation can be microscopic,what's preventing one from being macroscopic @memoryman.nothing.dr sheehan isn't the only demonologist around town so to draw a final conclusion from one man would be premature wouldn't you say?I doubt that he truly believes that no practical device can be made because I doubt that the people that pay him would want to set alarm bells off in public.

Textbook-compatible means you can take a textbook and check if you see a flaw in my statement @markE.you won't find one aside from a 2lot violation.you don't need a citation.what you need is to see if you can physically disprove my statement.or theoretically if you wish.

Profitis, I did not say that it could not be done: I said it MAY not be able to be made into a viable product.
Not all things can be scaled up or down due to limits of materials, forces. loads etc.
We can make large mirrors for telescopes, but are close to the upper limit for now.
