First noticed this when the design team at St Andrews Uni were getting a lot of praise: original design is for developing world use - a woodburner that converts some of the heat to electricity to run a fan which...blows air through it!!
More combustion, less poisonous fumes, and...spare heat converted to more electricity to power radio, phone, etc!
About the size of a Henry hoover.
So then they designed a Camping version for us rich (all relative) Westerners. It's not much more than Jetboil size. Charge up your MP3 player/phone from WOOD!
It is a rather wanky, expensive luxury toy, I suspect. But I really really really fancy one, even just as a toy. I don't have a smartphone, so bugger it, why not? <sits back to await deluge...>
It's gonna be a wedding present, from my work (thanks girls) to me an my new wife who LOVES cooking/camping. However, I have to admit that I'm the stove geek of the couple (Hunter, Kelly, Trang, old Primus gas cans, micro Chinese Trang, and, erm, a Jetboil).
