OT: Zeev, is this what you based your statement abour RT SC in carbon nanotubes on, or do you have a better citation? http://arxiv.org/PS_cache/cond-mat/pdf/0307/0307770.pdf. Stretched arguments in this one, if you ask me. Is liquid water at RT full of little crystals? Yes!--but try to pick one. I've just tried to put one in my evening whisky shot, but no luck...<G>
