schluppy that is a thought. Maybe flood a container with some other inert/non activating gas and then pull off the wrapper and insert it into the other container that has the piss in the middle. By surrounding the piss with heater media, more even heating would occur and less could be used and therefor device= smaller and less obtrusive. It could be 2 vessels one inside the other with a cap on each end. One for the piss and one for the heat media. then all youd need to do when piss was called would be open the cap to the heat side and wait 15 min and the open the cap to the piss and then pour it in the cup. What ever transfer of the heat media is going to happen is going to be done in an oxygen free atmosphere. The toe warmers would be an exellent choice because overheating wouldn't be a problem. I really like this idea, be cause it is passive, your only worry would be air getting to your heat media. As a backup if piss had been called and your chemical heating element had failed you could make a fake attempt at pissing and have a stored rubber maybe wrapped around the outside of your rig for emergencies, pour the qf into it and go back to the waiting area (Sorry I thought I could piss but couldn"t) and crotch it for a few and then make the dump into the cup. Later today I'm going to get some bottles and hot glue and see if I can make such an arangement. I also need to get toe warmers, I don't know where to get them except maybe cabellas, most other places this type item is more seasonal to cold weather and they are not stocking right now as it is 95+ every day here. Any ideas are welcome, please we need more input, many minds will help us get a good homemade device going. I found my cable maybe I'll post some shots of my previous electric rig for inspiration, althought the cloth bag is skunky funky due to over a year of ball sweat.
