A production run would need some more tweaking. I don't see that happening any time soon. My biggest issue is that I'm at high altitude right now and need to test the concept between sea level and 3000 feet to see how that affects it.

The biggest thing about ground scorching is the distance between the bottom of the outer can and the inner can. If it is far enough the heat shouldn't scorch the ground. There are a few factors, but that is the biggest one.
