Bay Area Heatwave

We in the Bay Area are currently experiencing a late summer heat wave. The local authorities have issued a "Save The Air Day" for the last couple and next couple of days.  Temperatures have ranging from the 90s in most places to triple digits in others.  As a consequence I’ll probably telecommute tomorrow and have to utilize my ceiling fan. I live in an apartment that tends to get stuffy at times, which makes fan usage a necessity. I should do the smart thing and take advantage of the current weather conditions and buy a couple of Solar Powered Fans. The purchase would be felt in the savings in my monthly electric bill.
