Using the Sun Wisely: Solar Shades & Energy Saving Awnings
It's 10 a.m. on a Saturday and I'm cooking an egg on the sidewalk, not in Death Valley but in St. Paul, and in a solar oven. The pace of solar cooking allows me to parent, write and ponder our civilization's future without burning my egg. I am using no natural gas and producing no carbon dioxide in the process. But the sun is not always available and a crispy solar pizza is still a dream.
