I’m at the very end phase of development

I installed what is probably the final version of the AC precooler. It works great. It was well thought out and went in smoothly. 4 screws, three line cuts, a touch of adjustment, and there ya go.
The added benefit was the air coming off of the AC unit was cool, like a swampcooler. Felt good on that hot roof.
We had a red sunset today. Dark red.
Thats probably what a martian sunset looks like.
