This is about two years old, but I ran across it on SlashDot today in the midst of the discussion of a guy that strapped a jet engine to a wheelchair (worthy of his own post). What tops that? How about this New Zealander:

It was obvious I had to come up with a better solution to the problem.
I knew from some long forgotten physics lecture that when a liquid expands into a gas it will draw heat from its surroundings. And I happened to have a source of a suitable liquid right in my shed in the form of a LPG cylinder. […] What I needed was a way to use up a lot of fuel very, very quickly.
What I needed was a jet engine!
