Self-reliance around the Web: three examples of DIY rocket stove designs

I've been looking for a good alternative to a fire pit for outdoor cooking. One of the more often-mentioned cooking alternatives is a rocket stove. Sure you could buy a rocket stove for $100 or so, but it makes more sense to build your own. Here are three inexpensive, Do-It-Yourself (DIY) stove designs.

If you're not familiar with rocket stoves, take a look at this rocket stove page (ironically on the Solar Cooking Wiki site), which describes how they function. If you're already familiar with them (or after you get back), check out these three low-cost designs:

This first design uses standard food cans to build a pretty intricate stove. While it's the most involved one to make of these three designs, it is portable, and closest to the commercial models:

Part 1 (how to build the stove)

Part 2 (finishing and using the stove)

Part 3 (minimizing dangers)

This next design is considerably simpler to make, but is not easily portable. On the plus side, the larger size may be more useful for larger cooking applications:

Perhaps one of the simplest rocket stove designs is this last one. By simply stacking 16 bricks, you can build a durable, fireproof rocket stove. It's not really portable, and it really needs mortar or better brick placement to be sturdy. However, it is very simple and easy:

Given these alternatives, I'm planning to build the Food Can version (the first one above).

How about you, have you tried a rocket stove, or built one of your own? Please share your experiences and recommendations below!
