Opinions... Lets say you have a massive solid based copper POT. If you drills holes down into the bottom of it, and fill it with copper BB's, and then solder them? You will have tons of surface area, because the acetone and LN2 will find its way around all the spherical balls and add tons of surface area and more mass.
Interesting... I like it. Not sure how well the cold would transfer from said BBs to the pot though..
They would be soldered and make minimal contact with the sides, but still making contact. circles have lots of surface area so the heat would transfer through the solder.
I have the sexiest chunk of copper sitting in front of me right now. it weights over 2 pounds... and it is going to be marvelous. I am trying to get ready for an entire weekend of benching. I hear lots of snow coming..?
