I have made several alcohol stoves (well dozens...) and none of them are as good as the 10-20 from Trail design.
That is my stuff works but it either they use more fuel or they are much slower.
Have done the same with wood burning stoves..
Several types including the so called down draught versions (Bushbuddy and co) and simpler 1 wall types like the J Falk stove.
(I actually arrived to that same design by trial and error then discovered it already existed)
Attaching a fan or using a pump (Liam you would remember the Hansa blower brush ) it does achieve a cleaner more efficient burn, that is less smoke and ashes but of course you do relay on batteries or your own patience.
The bio stove is a combination of the Bushbuddy and the Sierra stove but not requiring batteries.
BTW, the typical food cans will rust after a few uses.
