Diy body heating system... it's cold out!

[multiplexor]

Hey all

I was thinking about this for about a week now...
I've searched on the net and found some places that sell heated clothing.... but they dang expensive!!

how would you build a heated clothing system?

you can't simply run strips of wires down the length of your clothing... it would burn the material no?

I think this would be a cool diy project... dunno bout you guys?

If I wanted to do this in a simple way... with a battery and a variable resistor as heat control... what else do you think would be needed? We can throw our ideas together and come up with something generic we could all make hehe

anywho, thanks for the help

No. They sold electric blankets which worked well enough for many years. I believe that they finally took them off the market for safety reasons, but the fact that could sell them for so long before the safety issue arose shows that the percentage of times they catch fire was very low. If the percentage was high, they never would have passed the Underwriters Lab tests in the first place-or they would have been off the market in the first week.

How about a convenient way to transport a car battery around with you while you wear these clothes? Heating uses up a lot of electrical "juice". Just ask anyone who has an electrical heating system in their house.

Truth to tell, Multiplexor, I can't really blame you for thinking about this, though. Temperature last night:

Connecticut: 6 degrees F
Juneau, Alaska: 30 degrees F

It's not supposed to work this way!! Alaska is supposed to be colder than anyplace else.

Who do I see to complain about this?

Best is if your bodymovements can be linked
to a generator that can store/power the heat.

Maybe you can have a genrator built into your shoes?
I have seen some portable bodymounted computer system
work that way.
But microchips needs only a fraction of the energy
that a heating system would need.

Solar cells is not to be trusted
in the cold period of the year.
If you walk very fast (run), you might br able
to use some wind catching energy generator.

hehe i'm looking for anything... where it could warm me up for like 30 minutes even... this way next time i go out and when i finally start getting really cold, just flip a switch and warm up a bit... then flip it off

batteries are not an issue when i get cold... hehehe

[multiplexor]

you think supercapacitors could be used in this case? to ease the load on batteries? like the batteries turn on and off every 5 seconds.... load the caps and turn off...

just throwing ideas out there...

If they are no longer allowed in the US, maybe it is rather the
slight risk of electrocution that is the reason? I have never
heard of electric blankets catching fire, and they are still sold
here. Further, here in Sweden we have had electric heating
for car seats for as long as I can remember. Originally it was
in the form of separate things (not sure what to call them in
english) that you put on the seat and connected to the cigarette
lighter jack, but since long ago practically all new cars sold in
Sweden had built in seat heating. I have never heard of any fires
caused by these things. Actually, when I was very young we
had a Volkswagen Beetle, which had 6V electric system, and
my father had a heater he used on his seat in winter. When we
later bought a Volvo, he continued to use the same heater,
despite the Volvo using 12V and later I used it in my first car,
which also had 12V system. It heated up very quickly, but
catching fire? No, never!

yeah, i found some of these sites also

i think www.widder.com is another...

it's like everyone is making them for bikers... can't find anything for regular people who don't "ride".... those who go skiing and need the little bit of extra heat...
