Earth Day at IU East featuring Superfan & Misers

My son Mark Howell has been working on a 1.5x size Superfan project for the past year at the local university.  He was asked to participate in the "Earth Day" activities on campus a couple of weeks ago to demonstrate alternate forms of solar energy.  The idea is to power the fan by using a large magnifying glass, thus of transforming solar energy to mechanical energy (they did this outside - not in photos).  Also in the photos are Dad's original Superfan, Miser, and mini-Miser.

Here's a youtube video of the project:
