Solar Powered Hat Fan

Photo taken from my roof in Mt. Pleasant

Here's the newest innovation I've come across.

How does it work? There is a small fan mounted to the brim of this yellow cap pointed towards the wearer's face. The small solar cell on top powers the fan directly. There is no batter so it only works in the direct sun.

One of my colleagues at USIP has a brother that works at Wagner and Co. The brother acquired this hat at a conference and then my colleague passed it onto me. Once people know you as the "Solar Guy", random gifts and ideas start streaming in.
