I saw this one on Slashdot the other day science.slashdot.org/article.pl?sid=07/07/03/0228246&from=rss
Quote from article:
“Once manufactured under an exclusive contract with the US government, this recently declassified window film is now available to the public. But don’t expect to see it on store shelves anytime soon. Currently, it’s only available directly from the manufacturer, and at prices that will likely make it prohibitive for all but the wealthiest home owners. The two-millimeter-thick coating can block Wi-Fi signals, cell phone transmissions, even the near-infrared, yet is almost transparent… It can keep signals in (preventing attempts to spy on electronic communications) or out, minimizing radio interference and even the fabled electronics-destroying electromagnetic pulse generated by a nuclear blast.”
Think of the applications. How much do you think that stuff costs per foot???
