That article was... crap. Any explanation at all on how it works, what size molecules, the properties or structures of those molecules, would have been nice to know.
Hah, no way, too much math involved I'm sure. But something better than "LOOK AT STAR TREK! LOOK AT THE HISTORY OF TRACTOR BEAM FICTION!" would have been nice to read. My bet is only a very narrow category of molecules can move under certain conditions.
Awesome, supplemental info! Also, looks like they used a mirror, and the energy required would burn up any normal-sized item before moving it.
