Nimblewill Nomad stove (a.k.a. "Little Dandy stove"): Invented by Eb Eberhart. A solid fuel stove made from five flat, thin steel plates that assemble without fasteners, and unhook again and fold flat for storage. Used by him in 1998 during his 4400 mile, 10 month walk from Key West, Florida to Cape Gaspe, Quebec. This stove allowed him to burn anything at hand, and thus to carry no fuel. Smart guy, that one.
