Big deisel construction machines use them. My Dad used to work for a company that made a type of device like that. The big difference is those engines are a lot touchier, worked a lot harder, and were much more expensive to repair, and last for many times as many miles.
The difference of engine wear on a car for it's lifetime probably doesn't warrant the expense of the extra gear on the car.

- Nehmo - That seems like a workable idea. You could have a closed reservoir with (compressible) air on the top and oil on the bottom (perhaps a bladder dividing the reservoir). The oil-in tube at the bottom could have a check valve with the flow aimed in. Before you start the engine, you open a valve that bypasses the check valve.
You'd have to attach something like this on the high pressure side of the oil pump somewhere. I wouldn't know of a good place on my engine:
351M Ford. Maybe a place would be where the oil pressure sensor goes?I couldn't find a Google hit of what you're describing. You don't remember what catalogue it was in, do you?
Just light a fire under the radiator and then use your 12V pump to circulate the coolant. I think you are onto something here. I think you should talk to Detroit about your idea. You are well on your way to becoming a Bazillionaire. Someday, I'll be able to tell my grandkids that I knew you when you were a total nobody.

"farmer
- Nehmo - Nope, that'll never catch on. Farmers aren't known poor-quality improvising. Nor is the term "farmer" deprecating. "Jury rig" is an established term meaning about the same, but that's about all I'll say on the subject. It's has already been discussed ad nauseam in news:alt.usage.english and elsewhere.

- Nehmo - Ridiculous. The closed thermostat on the engine would prevent coolant from circulating between the radiator and the engine.
On its high setting, it would use about 4 times more than a PROPER block heater. That much external heat applied also greatly increases the chance of a fire.
You're putting 1000 watts through 100 feet of cord? What a waste of electricity.
Now I know you're a troll.

Aside from the fact that the orginal poster is yanking everyone's chain, a couple of things have been ignored in all these posts. First of all, the iron is very old. Electrical insulation from that age was very poor, and given the age it would be dried out and cracked. Plus an iron would not have insulation capable of standing up to the extremes of temperature that it would go through if used as a car heater. Thus we have old brittle insulation being made even more brittle by the cold temperatures. The insulation up until sometime in the 50's was rubber covered with cloth. Go look at a used appliance shop, flea market or antique shop to find an example of this. very scary, and very much a fire and safety hazard.
I am all for exploring new ways of using discarded items instead of trashing them in a landfill, and I don't concider myself to be a geniuse iether, but there is somthing wrong with this picture of using an old iron, it could only work if it had a thermostat that could be set to a certain temp to where it would shut off and come back on when temp drops again. Having it set on high seems a bit over doing it and pretty dangerous and I don't think your insurance carrier would like to hear your story about it. There is a saying tho' "Nessisitty is the mother of all inventions". GOOD LUCK BUB
Indeed - older wiring had very bad insulation. One time we had to wire a flexible segment of BX from a fuse box to a Hubble type outlet. Problem was, the fuses were cartridge type and the wiring in the box was cloth covered aluminum. We accidentally shorted a hot wire to ground and that lead to catastrophic failure of one of the cartridge fuses.
Needless to say the building wasn't up to electrical code and had to be re-wired.
Why not just build a good roaring fire under the truck before you go to bed ?
I actually have used the fire method years ago on DIESEL heavy equipment that lacked a block heater when it was horribly cold and in the middle of BFE.
I have used charcoal briquettes on many occasions.
I carry a hibachi or steel garbage can lid and fire it up to start my vehicle when coming out from a camping or fishing trip in -40 or so temps.
You have to be careful with it, but it will start all the vehicles in about a half hour under the oil pan each. We get one going and pile in to warm up while waiting on the rest.

I = E/R ohm's law
(120^2)/1,000= 14.4 Ohms for the iron
14.4 + .5 = 14.9 ohms total resistance of cord and iron.5/14.9 = three and a third % of the total resistance is in the cord.
Once you bake the insulation off of the wires internal to the iron, it will short out. If you're lucky it will blow a fuse or trip a breaker before igniting the extension cord. But, hey, knock yourself out.
yeah, but now your clothes look funny!
good idea for the pinch. sam

I worked in a plant that was built in the late 20's. It was kind of fun to guess when some section of wiring was installed. Of course, we would rip out the old wiring and run new whenever we had a problem.

What about power factor? Your solution assumes DC. An inductive heater is likely to have a lagging power factor.
