I started this project because I wanted to research better designs for steam turbines without spending the time and money required to CNC the parts out of metal, and i got results that were almost good enough to be usable for a light duty shop tool. The highest power i measured with a simple 2D turbine on 50 PSI was 16.4 watts. I did all my power measurements with a magnetic dyno.

I also built an aftercooler to remove some moisture out of the air, because I eventually want to use a compressed air turbine for the expansion phase of a brayton refrigeration cycle for cryogenic cooling (if i can get the turbine efficient enough).

Both turbine designs i tried in the video use a 1/16" diameter nozzle insert that's CNC'ed out of aluminum. The results at the end of the video are both shown at 50 PSI.
