Is it made of gelled alcohol? I see that some cans are coming with a wick in them. I'm not sure if that is an advantage or not, at least for survival. If it is not Sterno or a generic substitute then I would be very interested in knowing what it is. I've used Sterno (or sterno) for years and have never been able to get more than about 3 hours of steady burn out of a large can. If you don't mind please post the product details when you get a chance.

Edit: I wonder if it is the wick that accounts for the longer run time?
