I'll STFW, but if/when you run across the bookmark, I'd /really/
appreciate an e-mail!
I think Rossi is trying to get all the recognition without disclosing
all that would be necessary for that to happen. Too bad for him - he's
making himself irrelevant. :-(
I built my one and only water heating panel forty years ago come May and
managed to scald myself three minutes after turning it to face the sun
on the first test. E-mail me if you'd be interested in trying out (yet)
another approach. :-)

The bookmark failed me, but searching history yielded the culprit, which
I originally found in a forum reference:
I have not used them,yet.
Sure. I'll try to avoid the scalding though.
I ran another test a couple days ago. 5 gallons of water from 34F to
125F in the few hours before I stopped the test. I'm using a submersible
pond pump and I didn't want to damage the pump.
I'll try to get this plumbed into the house this week, and plug in the
other collectors. I'd like to be able to run it between 100F and 140F to
start off. Delta 40F at 100 gallons should give me 32K BTUs to get
through the night.

Thank you! Bookmarked them and just sent off an inquiry.
Good plan! My test panel was 24wx30h and, since it was a tiny panel and
an overcast day, I decided to suck cold water up through the panel. In
the minute or so it took to do that, the water got quite a bit warmer
than I'd anticipated - it took weeks for my mouth to heal.
As time permits, I'll work up a drawing for a panel like that and let
you know when it's ready.

Sketch is at http://www.iedu.com/tmp/SolarWaterHeater.png - it uses the
same fin approach as the air heater, and baseboard radiator (finned)
tubing in the heat exchanger. It's intended for vertical installation.
I'll leave it on-line through the weekend.

Thanks, got it.
What's the cost of the feedstock for the fins?
