Air Compressor Steam Engine

My brother Mitchell built this engine for his High School Senior Project. He took a regular engine and converted it to an engine that runs solely on compressed air. I would tell you more, but I know next to nothing about engines.
Sorry it's so short, our compressor is very small, and the engine would use all the air in a matter of seconds.

Read the description. Also, this video is a year old. We don't even have that engine anymore.
