I could dig up examples of nicer looking finned pots. The name escapes me at the moment, but I remember seeing one at a conference last year.

The point is that the technique was well known. It's not manufacturing or aesthetics that's been holding back the technology.

Here are a few I just found:

Eta pots (and similar models from jetboild who popularized the concept) are awesome but they aren't meant to hold up to kitchen use as they are designed to be light weight for hikign and climbing.

That is a good point. Although it might be popularity that was holding it back, and this article seems to have helped with that. I wonder how far this thing will go.
