Are you familiar with the work of Rear Admiral Grace Murray Hopper? She worked on the first compiler and developed COBOL for the US Navy. She was an aunt of mine, I got to go to the christening of the USS Navy Destroyer named after her (the US Hopper) when it launched. So cool.
We have family video of her sharp humor. She used to joke that people thought that she was a crossing guard because she was a woman in uniform, and at the time most people weren't ready to accept that idea.

Thank you for the important work that you are doing!

How do you keep your structures cool in hot arid environments, such as refugee camps in Ethiopia or South Sudan? Is it more important to insulate the roof of a structure or provide adequate ventilation?
