My friend Jake cam over with his Dad on Sunday and we worked together to make a steam turbine as a science project. Jake's design was based on a published design in the May 1960 issue of Mechanix Illustrated. The original article can be found on Scribd at this link:

After testing on the kitchen stove and making a few small adjustments the turbine worked very well. Here is a picture of Jake's turbine showing the various parts.
