Self-Warming Jackets

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."

microfibers, ok

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'm thinking Men's Health is not your typical slashdotter magazine. :)

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

Integrate it with laptops.

My titanium puts out a lot of heat - and I'm moving to Europe soon (Germany) - so I know it'll function quite nicely as a bed-warmer during those long nights.

Plus it plays DVD's, so in all it's pretty much like snuggling up in front of the fire and watching a movie ... in a tight little package.

If they could one day *use* the heat that these sorts of devices put out, instead of trying hard to reduce it, things might become a little more efficient ...

Keep the battery in your boxer shorts. Not only will it keep nice and warm, but if it gets shot you certainly won't be concerned with a little extra toxicity.
