Woodgas Stove

I don't see the CO2 is relevant anyway when burning wood, as long as it is not forest clearance and thus totally wasteful. With stoves, small amounts are used, and regrowth would scavenge the CO2 in the end.

From my reading of the Aprovecho site the upright tube of the stove in the video should be longer, about 450mm high and the shelf should be only one third the height up the feed pipe. A right angle elbow is also better and fill with insulation to the top.

As Woodburner says, the big difference in efficiency comes from using a pot skirt. The flue area should be about the same all the way through the system: the area around the pot in the skirt should be about the same as the flue pipe. And as Sam infers the rocket stove is more efficient and convenient for cooking rather than boiling a kettle.

Yer pays yer money and yer takes yer choice.

For building a rocket stove, there's a good video here:

I'd been wanting to make one for ages, but was clearly never going to get round to it, so tried to buy a ready made one. However, this proved nearly impossible, and then I found the woodgas stove.

One advantage the woodgas stove has is that it is ready to cook with very quickly, while a well-insulated rocket needs time to warm up I believe. But not having used one I can't speak from experience.

On a quality note, the one I got is made from stainless steel and seems to be very well constructed.

Would a small solar panel replace the batteries?

You don't want that comma at the end of the url:

Yes, but it would be large, and wouldn.t work at night, in the fog etc.

True. Thanks.

A panel might be useful to charge the batteries rather than run the stove. However, if the stove is for emergencies and not for backpacking, then an extended flue does away with power altogether.

I finally got round to doing a little wrote-up and video about this stove, it's on my blog: http://peplers.blogspot.com/2009/05/woo ... stove.html

Very well done Mike. The video is far better than the manufacturers video. You should do a license deal with them.

What a location, we live in one of the most tree-less parts of the country. Your coppice looks really good.

I'm always worried these videos look a bit cheesy, but as long as people are interested I don't mind...

Well, feel free to get in touch if you want to visit some time. Whereabouts are you that is so tree-less?

Not at all cheesy Mike, the best little video I've seen on that type of stove, well done
