What would you do with 50' of 7/8" copper tubing?

[walke2jd]

I got a 50' roll of 7/8" copper refrigeration tubing for a steal a while back and it has been sitting unused since then. Any ideas of how I could use it best?

Background: I do 5 gallon batches of all-grain. I currently have a 25' Immersion chiller.

Use that 25 as a prechiller and build a new IC with the 50. Youll be down to pitching temps in like 79 seconds.

You could sell it to me for cheap, no more worries then. I'd build an IC, it will have a lot of surface area and cool very fast. If you were to build a HERMS, you could use the 25' for the HX.

How about making yourself a CFC?
