I've put up a web page with photos taken during installation of a
pair of passive solar heating panels at
These two panels use neither fuel nor electricity, and keep the
building "shirtsleeve comfortable" through the winter.
Something to think about if/when your heating costs begin to get
out of hand...
I use a pool solar heater..

celebrated the completion of North America's largest solar
photovoltaic system with a ceremony at Nellis AFB, Dec. 17.
Weather _does_ make a difference, and although I haven't tracked
Pittsburgh's weather this winter, I can assure you that we've had
our share of gloomy and chilly days (-10 to 20F) here in Iowa
A really good solar panel (_any_ really good panel, not just
mine) will deliver significant amounts of heat even in complete
Agreed - Gary (the owner) seems pleased with the way it turned
Have you seen the BIG one down below Eldorado Dry Lake on the way to
Searchlight? HUGE, HUGE, HUGE. Next time you go to Laughlin, check it out.
Or just go for a short drive to Railroad Pass and take the road to Laughlin.
Just past the dry lake on the right. I am not sure if it is PV, or if they
are using parabolic heaters and a superheated brine solution like they were
talking about doing at the Nevada Test Site. It's BIG. A lot bigger than
the one at Nellis. I drove past there just a few days ago, and didn't see
it. But then, you can't see a lot of the base from the highway.
Good to know that our tax dollars are taking care of /somebody's/
electrical needs. I'm tempted to ask how long before the AF
announces its line-up of rechargable aircraft...
Hmm - is base housing electrically heated?
Having a new one installed in our vacation rental on Monday. $3700! The
old one (4) years was made of rubber tubing, and rotted. Oh, well. This
new one is flat mat and a new kind of material. Latest and greatest. Seems
I heard that before. Just in time for the lengthening days and swimming!
They're controlled by earth's axial tilt. In summer, the light is
reflected to the ground in front of the panel.
As winter approaches and the sun appears lower in the sky, the
panels "turn on" - and in areas where there's snow cover, the
amount of heat produced can almost double as the panels absorb
In summer, some energy will still be collected due to open-sky
radiation and reflection from terrestrial objects, and the panels
can be shut down completely by installing an opaque cover.
