36 is the number of circles inside recently installed solar tube diffusers

Tuesday, January 21st, 2014 in Inside the Numbers

36 circles are inside each diffuser of the solar tubes recently installed at Crocker/Riverside Elementary School in Sacramento, CA.

How do we know? Maddie, a student at Crocker/Riverside, told us so! In her thank you letter, she told us “[she] counted, circles in the diffuser, there are 36. And 9 solar tubes. I like the solar tubes.”

We received 25 thank you letters from students for the new solar tubes. Take a look at their inspiring (and adorable) letters here.
