Eneron Turbo pot heating efficiency?

[MarkT]

Has anyone tried out the Eneron Turbo pots who can give a report on their heating efficiency? I also found this interesting article:

which makes me think that maybe there really is something to be gained by pot design. The Eneron pots are pretty expensive, so I'm pondering building something like a flame-tamer plate with a finned bottom as a coupler.

I am interested in testing out a few methods to see what can be done to increase efficiency on a keggle. I wonder what a combination of a few of these could do?
