R. Buckminster Fuller

I was fortunate to learn about R. Buckminster  "Bucky" Fuller from my good friend Johhny Weiss at Solar Energy International.  Johnny spent some time with Bucky back in the days of John Denver and the Windstar Foundation near Aspen Colorado.  Johnny told me this story about Bucky. When Bucky was in school the teacher drew a line on the chalkboard.  Bucky asked his teacher, “What does that line weigh".  I love this story and the stir this must have created in the classroom.    Bucky was…

Lights, Camera, Energy Efficiency!

More energy efficient stage lighting? Yes, please! Theatrical lighting is found in many schools, churches, and local theaters.

Thankfully more and more new homes in Ontario are being 3rd party airtightness tested. Some do it to comply with EnerGuide80, some builders want to distinguish their build quality by having it ‘pass’ an air test or to meet a branded standard like EnergySTAR and many, surprisingly, still don’t get tested at all.
