NDSCS Student Mini-Fan build (MINIFAN)

Allen,

I used to send Jerry photos of completed engines that our students built, and since this is the 1st time we built the sterling fans, I figured I would send you a couple.
The build went very well, the students built 35 of them and every one ran like a swiss watch!

Feel free to share!
Regards,
Steve J.

"Mini Stirling Engine Fan" built by John Mallak of Hutchinson, MN (MINIFAN)

Jerry's Original Mini-Fan (MINIFAN)

"In the late 1800's and the early decades of the 1900's fans of this type were used the world over in areas where there was no electricity.

This model has a 5-1/4" diameter fan powered by a miniature modified Heinrici stirling cycle engine. This is one project that has practical value!

The fan runs at about 900 RPM and blows a nice breeze considering it's small size. The fan is cute in this small size, but if you want to move more air you ought to check out the 'Super Stirling Cycle Engine Fan' " - Jerry
