Simple Solar - Part 1

I presented a workshop on Simple Solar at the Boston Skill Share on a windy Sunday, April 19, outside the Stata Center at MIT. Werner and Julie of Videosphere recorded me and I finally got around to doing a rough edit of the first part, the simplest solar devices that anyone can make to disinfect and heat water and cook food.

It’s six and a half minutes long, I have the sniffles and say “All right?” a lot but the rest of the information is good. After all, solar heating is remarkably simple:
dark heats up
light reflects
clear keeps out the wind
