Has anyone seen for sale a battery powered jacket or vest to keep warm by. This would be preferable to heating a large living area. Would save lots of energy to only heat cold bodies as needed. A 12 volt DC vest could possibly be made out of an old electric blanket by using enough of the stitched in wire to be about 1/10 the overall length needed for 120 V AC.

Any motorcycle shop has catalogs where you can purchase one of those vest. I have ridden with people who have used those vest and they swear by them. The vest plugs into a connection of the battery, the vest has a climate/temperature control.
