So, I got a little 10 foot section of 1/4 OD copper tubing and put some thought into it. Figured out how to coil that 10' length into a double helix coil that was only a little over a foot in length. I plan to place it in the flask as it boils the DME for the starter. That will sanitize it all. Once it's done boiling, I'll crimp some heavy-duty foil over the mouth of the flask and set it on my stir plate. Once the wort is stirring I'll then start the flow of the chilling water. I bet tap water will work great... though I also plan to try to pump ice water through it with a recirculating pump and a 5 gallon bucket.
It's not quite done yet, it needs fittings and to also put some hook bends on the end to hang it off the mouth of the flask. Also, this is meant more for a 5L flask because of the huge thermal mass compared to smaller 2L flasks. I look forward to trying it out to see how fast it chills the starter compared to the Ice Bath I am used to using.
