Survival Still Grill

One of the things I love about the survival still is how versatile it is. In today's video we use it on a charcoal grill and tried to test how much we could get, unfortunately it began raining and messed up our semi-almost scientific test.
This is probably the most important test of the survival still, because if you ever have to actually rely on the still, you may not have any other cooking method other than the trusty campfire.
Once again, if you rub bar soap on the outside of the bottom pot BEFORE you put it on the fire, the soot will clean up much easier.

Shepherd School - I am interested in this Still but wary of their stated 1 gallon every 2 hours they advertise.  Have you done more formal testing to verify exactly what the output is of the Survival Still?  I have done some testing and can't seem to get close to that with other still techniques.  Thanks for any insight you might be able to provide.  J
