Beyond the Trough - Thailand

​"Lots of people expressed interest in the post-trough, post-Kontiki, tench solution to making char in the field without water. Here's a really simple, two minute video shot using our original test trench. In a few months when the corn harvest is in, I'll shoot a more real one up in the mountains. For now, this will have to serve. It is not, as you will see, rocket science, and as long as you dig the trench during the rainy season, there's not much work involved."
