Not too impressive though. Using the energy equivalent to the consumption of a small town they create an area of "transparency" (well to certain high energy frequencies of UV) a fraction the diameter of a human hair for a small fraction of a second. I can do rather better with a small electric drill - less energy, a larger area and true permanent transparency. I think it is the way they write the headlines...
