Check out the Beautiful Design of This Rocket Stove!
The cutting edge of sustainable low-tech cooking these days are rocket stoves.
This is Chris's first rocket stove, and now he's seen it in action he's planning to refine the design of the next one. But I'm finding its a pleasure to cook on as well as look at. The stove had its first run cooking steak at my housewarming party in the weekend.
Since then I've been cooking simple meals every day using just a couple of handfuls of twigs. I'm out of practice with lighting fires and while I am getting my skills back up that's the most difficult part of the operation (and its not that hard!). Once the fire is going you just have to keep feeding twigs and sticks in through the fuel magazine, so its not the kind of cooking you walk away from for long (but really, most cooking requires regular attention anyway).
