Then you weren't paying attention.  All you need to do is scroll up a few
messages and it will all be clear.

Or not.

What I do know is that not including *any* of the thread (see your
original post in this thread) is abysmal usenet practice. Why Nick even
responded is beyond me.

Congratulations, Jeff, at least ONE person got my point.

For the rest -- Losers who quote NOTHING of the post to which they're replying
have nothing at all to say worth reading because they aren't smart enough to
let the readers know what they're talking about.  Alternate:  They're so
enamored of seeing their deathless prose in print they don't care that nobody
knows what they're talking about.

Thanks for explaining. Abby and m Ransley sometimes do this. It can be
an interesting puzzle with a solution. Other times, a complete mystery.
Amusing cluelessness.

I imagined you meant the original attic wasn't solar, so the new design was
not an "improvement." I meant that it seemed to be an improvement compared
to the 20 or so solar attics built in Soldier's Grove, WI about 25 years ago
when that sensible little town turned down $ million from the Army Corps of
Engineers to build dikes and moved its commercial district uphill (after too
many Kickapoo River floods) and then passed a law saying all new commercial
buildings must be at least 50% solar-heated (see the Solar Today story at
http://www.ece.villanova.edu/~nick , if you like.) Most of their large empty
solar attics have sloped glazing with a large blower moving hot air down
to the lower part of the building and a motorized damper to keep building air
from rising back up into the cold attic at night, but that uses big ducts
and lots of electrical power, and it's hard to store heat from warm air.
Some buildings store no solar heat. Others store heat in rock beds, hollow
floors, and shelves of canned goods in the IGA supermarket.

As to "improvements," this newer design might have a higher solar collection
efficiency, with cool air next to the glazing losing less heat to the outdoors.
It might also collect and store heat in water, which requires less electrical
power and makes for easier heat storage and water heating for showers, and
the glazing is vertical, which allows an overhang for summer shading to avoid
overheating and extend the glazing lifetime and make more of the attic space
useful for people. Corrugated greenhouse polycarbonate glazing (eg "Dynaglas")
has largely replaced the fiberglass glazing used in Soldier's Grove, since it
costs less and installs easier and lasts longer, with no maintenance. My roofer
neighbor envied my solar roof as he watched it go up in a day or so in 4'x12'
sheets, with no sheathing, felt or shingles. It costs less than a normal roof.

Are you sure you are not Rod 'the Rocket' Speed's alter ego?

You like to suddenly cross post solar and frugal stuff all the time
half way through a thread plus you have a similar pattern of deny,
deny, deny when you do not have a clue, comparable to wet paper bag,
blotto and ignorant pig.

I was surprised that as the rocket you mentioned swamp coolers tho.
