I love this web page

It turned up immediately in a search, it has exactly the information I needed on the front (only) page, and I probably know enough code that I could make one like it if I wanted to do so.  I might add a photo of a solar hot water heater, but what the heck.   This guy takes care of our (Carter-era) solar hot water system. I *want* him to be old-school.
