If I can't find oxygen-free copper

[k4kyv]

This ad ran in our local newspaper this morning. I just can't wait to buy one... as soon as I get the money from reselling my $600 hospital-grade a.c. line cord.

"This advanced heating element was discovered accidentally by a man
named John Jones. He had a large old farmhouse that was impossible to
heat. Jones had a coal furnace in his basement. Jones placed a sheet
of cured copper next to the furnace to store it. Cured copper is a
type of copper that goes through an extensive heating process that
gives it <span style='color:Blue'>special properties</span> (http://www.cabling-design.com/forums/Re-How-do-you-Stop-a-Scam-Edenpure-Portable-Heater-article41279-50.htm). After the fire went out, Jones noticed
that the copper was heating his entire basement evenly, even though
the furnace was no longer putting out heat. He also was amazed at
how long the heat stayed in the copper and continued to warm the
room.&quot;

Yep copper is a good heat sink. Read all about it:

One EdenPURE heater and a bottle of Hadacol - you're ready for Antarctica.

I like the ad. It says, &quot;Not BTU rated.&quot;

Now, isn't that special, for something that's supposed to warm you up? http://www.qrz.com/iB_html/non-cgi/emoticons/smile.gif

I have a 2m/440 jpole up at my QTH for my home radio.

So, if I made it out of this material, I wonder if it would retain the RF heat for a much longer time period?

It would definetely make people look on a cold day if I was transmitting and the antenna was steaming or something because of the retained heat....

Does Hadacol makes us cured Hams?

The sort of scam that pisses me off is the larger, bolder, scam directed at millions of people. My Mother-in-law, bought two of those Sharper-Image so-called air cleaners. They are less than useless as they can run all week and collect less than a thimblefull of pollutants.

I say &quot;less than useless&quot; because they are extremely powerful emitters of QRN across the entire HF band.

The &quot;ionic B.S.,&quot; you mean?

The invention pre-dates WW2 and in 50 years nobody figured any good reason to use one, but leave it to slick marketing to find a way to sell them anyway.

Actually this would work. Forget the oxygen free bunk.

Iron # # # #0.45 Joule/gram Deg C
Granite # #0.80 Jouls/gram Deg C
Copper # #0.38 Joule/gram Deg C

So, forget the Copper and get Granite. Place a huge granite structure around the fire, and place some air vents within the structure with vents. Place a bunch of wood within this structure - preferably on an Iron grate and whola - heat and time to enjoy.


Wait, I think I will call this a FIREPLACE.


Don't steal this idea. I am driving to the patent office ASAP.

Bob, you forgot one thing, matches ! You can have a mountain of wood in the fireplace but if you don't get some paper and a match, your gonna be cold.

No, when I was in the Boy Scouts they taught us to make a fire by rubbing two Girl Scouts together. http://www.qrz.com/iB_html/non-cgi/emoticons/tounge.gif

too funny, I do love my copper base pans for cooking though, it does give a very even heat for cooking,
but yeah those Ionic brezes are piece of garbage

Oxidizing is also known as rusting. Copper oxidizes when exposed to air and is heated. #The hotter it gets the more it oxidizes, simply because burning and oxidizing are really the same process. # You can not light a fire in a perfect vacuum #That is why even in a good vacuum the filaments of incandescent bulbs do not quickly burn and melt open. #
Copper gets the oxygen from the air when it is hot and forms copper oxide on its surface. #Copper oxide has a greenish color. #Iron oxide is red rust.
The electrical resistance of copper wire increases as its temperature increases. #It thus has a positive temperature coefficient. #Oxidation functions as part of the reason that copper has a positive temperature coefficient.

Maybe &quot;pure&quot; if it was put unoxidized in oil for storage. There is your pure. http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

If the heat stayed in the copper, how did it get into the room?

That's the problem with copper. It absorbs all the heat in the room.
