Jon, I'm interested in that little wax burner, too. Here is a good video of it:
Here is an amazing video of a prototype stove (same inventor) burning wax with forced air:
In the first video it seems that the flame might be somewhat sooty, particularly when the pot is removed. In the second video, though, the flame is blue. It seems that a little more air is all it needs to burn very cleanly.
If this stove could be made from titanium, with a lightweight (aluminum?) wax reservoir and a little fan with a Lipo battery to supply air, I think it could compete with the performance (heat per unit fuel mass) of butane/propane stoves, but without a gas cylinder (just a bag of wax bits).
