look into rocket stoves or rocket mass heaters for cooking. i want to build something like this eventually. would be great for hanging out and boiling sap for maple syrup in the winter. i forget if this guy was here or a different forum.
Yes, Walker/Broaudio is here. I know about rocket stoves. I have used them for cooking. A gasifier would be something new and fun. Almost the same technology. I am even going to combine the two. Actually a gasifier might even be a simplier and more efficient way to use a small cooking stove. I'm hoping to build one this week or next.
