ok. I am on a quest. i want to make my own heated gear for my motorcycle. Initially i was looking at using nickel wire and thread a vest to get the heat.... but then i came across one that produces infared radiation. the difference is that with the nickel wire, the vest would suck down 45-65 watts to heat, vs with the infared radiation emitting device, <35 watts is needed. it seems to be some sort of carbon with ceramic fibers or something.... curious if anyone could shed some light on this... the vest that has this new technology is 300 bucks.... yeah, i know i can make it cheaper...
