The heading is in the claim in the link below. The reality is ... ??? http://www.wired.com/news/technology/0,72134-0.html?tw=rss.index 3mm microwave causes skin heating to pain threshold with user tolerances of 3 to 5 seconds max. A number of pictures, some or all of which may or may not be genuine. Even has named people from Sandia labs doing demos. The claimed cost of $40 million over 10 years is too low or too long or means it doesn't really work very well. Nobody spends "so little" on something with such promise or takes so long if it works. No non lethal weapons are, of course. Some are less lethal and some aren't weapons. Gargoyling the persons' names shows that the picture of the small area ADS (active denial system) appeared eg here http://blog.tmcnet.com/blog/tom-keating/technology-and-science/ray-gun-protects-nuclear-power-plants.asp in July 2005 with their names and lots of details as a nuclear power plant protection system - so there is indeed nothing new about this system. Sandia themselves have a June 30 2005 news release here http://www.sandia.gov/news-center/news-releases/2005/def-nonprolif-sec/active-denial.html with another of the photos from the "latest news" and a marvellous 300 dpi 988kB 5 MP JPG here of the two with their toy. http://www.sandia.gov/news-center/news-releases/2005/images/nonlethal-weaponry.jpg 5 MP image EXIF says it was taken on May 19 s005 and has been through Photoshop. IF this is real one could learn much from this image. Not quite pocket portable. Feed method of the 'dish' is unclear to me. A 'dish' this size on a 3mm device implies a gain and a degree of focusing / that defies imagining. The military vehicle mounted system in the wired release is larger again.
