Great stuff. Ive just returned from a 2 month cycling trip in spain. It was fantastic and I felt I could carry on living that way for a long time except.... When its raining and you crawl into a tiny cold wet tent and your sleeping bag gets wet, then the next day you climb into wet clothes, cycle wet all day and then get back into your wet tent and sleeping bag the next night. So the problem is having no way of getting yourself and your stuff dry. So i spent a lot of the trip fantisizing about having a larger tent with a lightweight wood burner in. Now this beauty approaches the problem well. I like it alot, however although 5 kg is great for a wood burner, I probably would be willing to carry it on my bike. The problem with making a stove in the weight range i'm thinking of is not only durability but the fact that as soon as you stop feeding it, it'll go out and rapidly cool down. The more mass a stove has, the longer it'll give heat out for. So i've been thinking about a hollow walled thin stove, that you can fill with sand/earth/rocks from your locality when you arrive at you camp, in order give it a bit of thermal mass.
On your blog entry, you mention installing a Silicon panel in your tarp. Is this heat resistant then? What form are you refering to?
Cheers
