Self-Warming Jackets

Posted by michael on from the virtually-zero-electrocution-risk dept.

jeffy124 writes: "Those of you in the frigid north who find their coats unfulfilling of their duties may be interested in a self-warming jacket. By using steel microfibres woven into the fabric plus a lithium battery, heat is actually generated to as much as 114 degrees fahrenheit. The jackets, sadly, come with a nasty price -- US$500. Among those interested in purchasing are skiers (including some Olympians), and the Military."

    for a second I thought that was steel wool. There's the poor man's version of this. Wrap yourself in steel wool and apply a lead acid battery. "Oh, ow! put it out! put it out!"

    -Do NOT do that.

    I was told by some DARPA person that one of the problems the military had with wearable tech was that a bullet which has just travelled through a lithium battery was more toxic than one which hadnt; wearing a coat with Li-ion elements is not the kind of thing you'd want to do on the battlefield. is that correct?

      So put the battery in the helmet. Lead poisoning of the head is almost always fatal, so a little lithium won't hurt.

    How many of you have ridden motorcycles in a cold winter climate? I don't care how many layers you have on, what nifty fibers they contain, etc. If you wear something that doesn't breathe, you end up covered in sweat. If you wear something that does breathe, you freeze at highway speeds. That's why heated electric vests are so popular.

    I've only been riding motorcycles for about 28 years, so I expect there will be some people that weren't born when I started riding that are sure that they know far more than I. You will find their responses following this.
