This stuff seems like science fiction. Small-object visual cloaking within five years? Room-temperature levitation? Really!? That would be, uh, somewhat revolut

  It reads like science fiction partly because there are things this makes possible that seem to go against everything the 'bedroom scientist' would think. Some of the things this mentions I had no idea about, but the core EM-cloaking seems to be described quite reasonably. Just don't believe the timeframes. They are very optimistic from all I've read of this technology, especially if you're interested in doing much more than cloaking a coin from most visual frequencies in the next decade or two. Long term promise in this field seems quite great, but I'd say we're way too early to be able to even guess what the drawbacks and limitations of any practical use will be.
