Happy summer in California

This is pretty amazing, it's like 65 degrees, it's New Year's Day, January 1st.

I've been spending lots of time on the beach. I love it. It's warm and sunny.

On the days we've actually had winter weather, I have found ways to use passive solar heating too: I just open up the door to my box, park facing south, and make the huge 3-sided solar collector known as "The Cab" do its work to heat the place up.

It was cold enough a few weeks ago that I realized there's a huge oversight in my insulation: the floor! The floor is not insulated at all. And it was getting freezing cold in here, due to the floor. So I have to go buy some isocyanaurate sheets, cut them up to fit in between the beams of my box, and insulate the floor. Then it'll stay toasty in the winter, and, I think, stay cooler in the summer too!

I noticed last summer that the van stayed so wonderfully cool in the mornings on hot days, but as soon as the afternoon came it got way too hot. And I couldn't figure out where the heat was coming from. I think heat was rising up off of the road in the afternoons and heating the van up. So maybe insulating the floor will help me this summer, which, if this is any indication, is going to be an exceptionally hot one.
