Thanks for the link to the Littlebug! I do like the Bushbuddy but nice to know of the bug too. The ability to pack flat is crucial in space savings. I'd like to see someone compare the two in a burn off.

Here's James' homemade Sierra Zip-Stove on a thread at Outdoors Magazine. James even put together his own fan.

I'd like to try to build one of these some day.

If you scroll down to the section "Wood Burning Stoves" at the Zen Backpacking Stoves Site, you'll find a number of plans for stoves of the wood burning/gasification kind.

Check out the Wilserness Way magazine Vol 14 issue 2 pg 28

It shows how to make the Bushbuddy stove

I took a big coffee can, dremeled a vee about a third of the diameter of the can with the apex 2 inches above the bottom of the can. Opposite the vee, I punched 6 holes at the bottom with a church key. I took an old piece of rubber tubing and stuck a short metal cylinder on the end to create a blow-tube. It burns twigs, pine cones, cardboard, whatever. It contains the heat and makes the fire easier to start and easier to tend. It does not gasify, it does not fold up, and it lacks, shall we say, elegance. But it is cheap, lightweight, and requires little skill to create. I suspect that it performs about as well as the commercially available units. and lots better than an alcohol stove. It is a messy thing to carry around, but fits nicely in a USPS tyvek priority mail envelope, which those folks give away. Notice a theme here-I am thrifty. And unskilled. This thing suits me well.

(I am sure that the plan was on the Zen stove site, but cannot find it).
