This is a USB-powered personal fan that hooks onto your necktie— you know, in case you are looking to stay cool and not get laid this summer.
The 28 gram Tie USB Cooler is sold by Japanese accessory maker Thanko. It clips to the backside of your tie and is designed to push a steady stream of air through the button gaps of your shirt. Just plug it into any available USB port for power, or use the included battery pack to stay frosty (and un-sexed) while mobile. Unfortunately (or perhaps not), it's only available in Japan and retails for about $35. [Thanko via The Washington Post]
