The potato cannon uses the basic principle behind any reciprocating internal combustion engine: If you
put a tiny amount of high-energy fuel (like gasoline) in a small, enclosed space and ignite it, an incredible
amount of energy is released in the form of expanding gas. You can use that energy to propel a potato
500 feet. In this case, the energy is translated into potato motion. You can also use it for more interesting
purposes. For example, if you can create a cycle that allows you to set off explosions like this hundreds
of times per minute, and if you can harness that energy in a useful way, what you have is the core of a car
engine!

in the passage above.
