A compact alcohol wick stove made from copper plumbing.
I have cooked quite a few individual meals with this stove and have taken it backpacking. It is a little heavier than the ultralight stoves and It is not as powerful as compressed fuel stoves but I like the fact that it is durable, stable, refillable, and it uses relatively safe, clean burning alcohol; stored in the stove stand itself so I don't have to carry a separate fuel canister.
It is made from fairly standard copper plumbing supplies found at most big box hardware stores.
My personal motto: "If I can't find it at my local hardware store I don't build with it." I hate special order parts!
