Yeah the ladder was filled to about 1atm. The pressure would rise when it heated and decrease when it cooled, though. I ran it for like 5 hours last night and the bottle barely got warm. Before I added the argon, with just air inside, it got hot rather quickly and was about to melt. I don't know what the difference would be, but there clearly is one.
It might be that air is a better conductor of heat than argon? So cool, I got to try that out.

Hi all.
This is my cool pic...
After seeing John Freau`s toroids some years ago, I wanted to spin some discharge terminals myself.
So I have used a lot of my spare time at the department I work in last week, trying to spin Al. and copper. The only problem with spinning discharge balls, is to make the form... But at my work we have some really big steel balls, from some huge 100-160 tonne mechanical stamping machines And they fit in a lathe perfectly!
