Most people here will know them as a rocket stove I think. ;-)

What they all said plus...

Will it have enough Btu's to boil a kettle in a reasonable amount of time (5 mins?)

Will this be small enough to be transportable?

As I understand you need to control (limit) the amount of oxygen to the chamber with the fuel in to achieve the gasification? How are you going to achieve acurate enough control? How accurate does it need to be? Are you going to calculate the air flow or go by trial and error?

I have a number of stoves, backpacking and family camping one ring and two ring versions. What's most important for me is pack size, cost of fuel, overall design, i.e. are the stable, feel well built, can fit two pans, will it be reliable.

It sounds a really great project and if you need any feedback on the design feel free to check back in. Not that I've actually made one, but have a reasonable grasp on the physics/ maths.

This is quite some project.
You want to place a portable town gas works outside every tent.
Town gas was mostly carbon monoxide which is poisonous. The poet Silvia Platt and many others committed suicide by sticking their heads into town gas ovens.
There have been deaths in tents from using charcoal grills (bbqs) in the confined space of a tent. Burning charcoal produces carbon monoxide when denied enough air.

I want a lightweight gas stove, that I can control and is safe. I accept the risk of setting fire to my tent with a flame that I can see, I do not want a colourless odourless gas loose in my tent that could kill me in my sleep.

There's already a couple of wood gasifiers on the market - take a look at 'Wildstoves' online & there's already a model called 'The Woodgas Stove'.

I've used one & they're fine & have their devotees on most bushcraft forums - you may like to contact them as they are the ones who camp a little more on the 'wild' side. Every woodgas stove I've seen has been a one potter though.

The main problem with these is fuel - if there's not a ready supply to hand then you're carrying it. If I have to carry fuel I'd use a more efficient cooking system eg liquid fuals that last longer & generate more BTUs. I'm a bit of a dinosaur & use Trangias & paraffin stoves.

Good luck - an interesting project

. So far I must confess that I've only used it with the Trangia meths burner for convenience (hence the sooty pot).
