What was the fuel source? What type of fuel? How was it lubricated? Where was the exhaust? How was it started?
A lot of questions on this. However, it was neat to watch the video. Thanks.
Edit Note: Where were the head gaskets? I saw no gaskets at all.
^^^This^^^. If you view it on the youtube site and read the comments, it's powered by compressed air. I wondered too because I didn't see any provision for water cooling.My best guess is the engine is run off of compressed air as there was no fuel system nor ignition system.
