Hey, I'm a GGG burnout... Oh, wait, you said burn off. ;)
I was super impressed by how fast Mark (I think it was Mark) boiled water with a BCB. Yeah, that Microburst helped tremendously, but I've run a BCB against an Emberlit and a Firefly before, and it's just a danged good design.
I was a little disappointed by the Biolite (I was running the Biolite). The Biolite has a self-powered fan. Once it gets going, it's faster than a bat out of you-know-where, but it's a bit balky to get started. It's got a tall, narrow fire box. I find a wider, shorter fire box (or at least wider) is easier to work with. The Biolite in my so far limited experience (got it in October) is really tough to start with damp wood.
The fact that Rick with his home-made coffee can stove was able to equal or just slightly beat the Biolite is a credit to Rick's fire making skill. Rick used his Mora knife to create a lot of shavings and really prepped his fire lay well before starting his fire. Josh and Mark used Mora knives to prep their fire lays too. If we do a wood stove burn off again next year, I'm definitely bringing my Mora knife.
I do think we need two categories though: fan assisted and non-fan assisted.
An alcohol stove burn off is a cool idea too, but it's not just a matter of speed if you want a practical stove. Maybe you'd do it as least amount of fuel used to boil 2 cups in under 15 minutes or something like that. I mean it's cool to have an ultra-fast flamethrower stove, but it's going to eat fuel like no tomorrow, and no one will ever use it for backpacking.
