Yes, please. Trying to cool yourself off on a very hot and humid day is agonizing. It really feels like your melting. And it's even more difficult when you have to get out of the house to go to work or school. But you would have to suffer all day from the heat. No more! Sony will be bringing to us this new invention: a wearable air-conditioner.
Sony calls its personal air conditioner the Reon Pocket, and it’s worn just below a person’s neck in the pocket of a special undershirt. Once the device is in place, the person can control it using a smartphone app.
According to Sony, the Reon Pocket can decrease a person’s body surface temperature by 13 degrees Celsius (23 degrees Fahrenheit). It can also raise it by 8 degrees Celsius (about 14 degrees Fahrenheit) if you wanted to use the device in the winter months to stay warm.
Currently, Sony is crowdfunding the project by taking orders on First Flight. Once the goal has been met, investors can expect their device around March of next year. However, for now, it's only available in Japan.

Peltier devices are terribly inefficient air conditioners, so they generate even more heat for the little cold they put out. Being wearable, that heat is going to be released very close to your body. If the wind blows the wrong way, all that heat will come back into your face. And they really need a fan to function, so it won't be silent at all.You know what would work a whole lot better for any given amount of battery power in 99% of situations??? Fans just blowing ambient air over your skin. A much better cooling design would be one of those blue ice pack things, in an insulated box, with a temperature controlled damper and fan blowing the cold air on you. You have to throw it in your freezer to recharge, but it would actually be able to do a decent job, unlike this concept.If you really seriously needed active cooling, you'd go with either the common chemical ice packs as needed, or cans of highly compressed gas with temperature regulators. Liquid nitrogen would of course be an excellent choice, but even simple computer blowers or hairspray cans demonstrate the same cooling effect when they are discharged.

I'm not sure a personal cooling device is the answer we're looking for. There are many other things like fabrics and materials that could be used to cool instead of hooking another device to your body. Sure it sounds cool but is it the easiest solution?
