That's very interesting. Ever since I used SunTex screens to cool off my Den,

and noticed they didn't reflect solar, but absorbed it, I wondered if it could
be used in a flat-plate solar hot air collector.. And now, I know!

The Phifer 90% sun blocking screens at Lowes looks like the the SunTex stuff.
But maybe even better. Gotta go back and read Gary's construction info!

Edit:
Heck, it's the same stuff..

I was just thinking about the solar gain from the light reflected off a foot of white snow..
