Stirling Engine turns on and gets cold

My friend David and I turned on a Stirling engine on Friday. The engine is a Cryotel CT from Sunpower in Ohio. The device is capable of bringing a cold finger down to cryogenic temperatures such as near the evaporation temperature of nitrogen. In the embedded YouTube video, you can see us turn on the engine for the first time.

Here is also a picture of some cookies I made and some butter chicken I made.
