I have a Deadwood Stove. I bought it a few years ago because I liked the idea of it not needing gas, electric, or charcoal. It burns pine cones, twigs or small scraps of untreated wood. It's big enough for a cast iron pot or frying pan, and is easy to set up and take down.
The Deadwood Stove is a type of rocket stove that is built in the USA. It's a bit pricey, but well built. It is easy to light and quick to get hot. Regulating the temperature will take a little time to get used to. The stove gets very hot so extreme caution is needed if small kids or pets are around.
The stove is a bit heavy so it's not for backpacking. I store mine in a plastic storage container and keep it in the back of my truck. Thing I don't like about it is that it can turn the bottom of the pot or pan sooty, but I still think it's easier to clean than the charcoal grill. There are a lot of similar stoves out there so look around, here's a link to mine.
