Self-Warming Jackets

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

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."

  1. Electrically heated gloves, socks, etc. by Animats · · Score: 1, Redundant

    Electrically heated garments date back to 1913 and the early open-cockpit aircraft days. Electrically heated gloves and socks are common. But battery capacity has been a problem. Lithium-ion batteries give about a 2x power density improvement, so that's a step forward. But this is hardly a new idea.
