	My (Rasmus) opinion: these types of open-burn kilns appear to have some advantages over those "barrel-in-a-barrel" retorts that were advocated in the past. This kiln does away with the internal metal barrier which is costly, corrodes easily and is labor-intensive to make. Instead, it has a "flame cap": the flame itself is the cap. The Kon-Tiki kiln can be tilted after the burn, allowing the [[biochar]] to be dumped out easily for further use. The char produced with open burn kilns may be of higher quality, because volatiles and tars can evaporate more easily (a recent [http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0154617 paper] provides supporting evidence for this).

The Kon-Tiki Kiln can be quenched with water. This "quench water", which is soapy and alkaline (due to a certain ash content), is a potentially valuable byproduct that can be used in other processes.

	This kiln produces large amounts of “waste” heat that could be used productively. The main issue to consider is that the “open burn” principle has to be maintained: the ambient pressure in the pyrolysis reaction should not increase when heat is captured. This may be achievable with a smokestack of sufficient height and proper dimensions.		This kiln produces large amounts of “waste” heat that could be used productively.
