little oven element
 

I was looking over the little convection oven I have and fond four elements. 2 are used to go to 450F then four...

I ponder making a heater, all in one for the car.

I have yet to figure the fairy tale with 12volts. it can be alot bigger than what we are constipated with.
I am thinking power invertor, little element, about 300watts, I mean tiny element, it is a bout .25 diameter by less than 12X10 shaped in a "u". A metal lined whatever box..

anybody done this? I also ponder a .25 amp computer fan, to mimick a convection, or flow to start then let it get sucked into car recycle vent (I have mine 50/50 outside/in permanent)

I was hoping to do this before the melting glaciers killed me with hypothermia in a heated room..:confused:

How about one of the pre-made dealies for that? Anything connected to your cig. lighter socket is going to be limited to under 150 watts because that's all the socket can supply - but there are some direct wire ones good for almost as much as a household space heater.

What's your goal here? What are you trying to heat? :confused:
