Janmarsh, Sounds like a job for someone with free energy. I hope all you guys in the Mojave dessert are thinking about this and working on your mirrors.  Manta |

Speaking of Mirrors... One time in the dead of winter in Vinton.Ca. about 25miles north of the nevada border where we drove to Reno every day for work... out waterpipes froze solid
and we were left without any water for about 3 days... I had a heat tape on it but it evedently burnt out and quit working... anyway..I was desperate to thaw the silly thng out
and the pipe was thawed from the ground up but the pipe came out of a pored concrete slab...
and I couldn't heat it enough to get it to thaw out......after running out of propane in my propane torch and the pump quit working on my old gas blow torch... I was left to wondering how to get the thing thawed out... the sun was out and very intense but in the shade it was a good 11 degrees !....
It so happened that the wife and I had purchased about 5 boxes of mirror tiles and were going to put them on the bathroom wall... so I got the idea of sticking the mirrors on the ground and focuseing the sunlight on the cement slab...
after putting out all the mirrors and re ameing them about every 15 minutes I noticed the snow on the concrete starting to melt... I went in the house and got a cup of coffee and warmed up a bit and then went and re amed the mirrors again... this went on for about 2 hours and then Woosh I finally got water to flow again...
After turning it off , re hooking it and hooking up the NEW heat tape I gathered up the mirrors and went in the house to warm up... the wife came home and wanted to know how I got it thawed out and I took her out to the concrete slab that was still warm to the touch and she said You did that with those mirrors ? I said Yep... but I think I'm sun burnt !
HAHAHAHAH
....
it realy is amazeing how much heat you can get just by doubleing the sunlight then trippleing it , then quadroopleing it etc,etc....and with 50 mirrors all pointed on the same spot it was too hot to hold your hand in there ! HAHAHHA
...never thought I'ed make a solar heater in that method but despret times calls for despret measures ! HAHAHAHHA

Bob, I can believe it. Solar is THE way to go if you get lots of sun. The outside air temp doesn't matter as long as the thing you are heating is insulated from the cold air. Over here we are only seeing the sun once in every eight or nine days. As I look out now the cloud cover is a little brighter in one place; that's it. Pretty miserable really. When I retire (soon) I hope to move out to an island in the Aegean. Lots of sun there.  Manta |

I have a great big 13' satilite dish and I alwayse wondered what that thing would do if I covered it in mirror mylar and put a 2 gal tank painted with high heat black paint on it and tracked the sun.... I bet that would make enough steam to run lots of goodies !
heat the house and a bunch of rocks in the day time and let them radiate the heat at night for the house... run a steam generator... not to mention heat a swimming pool ! HAHAHHAHA
... thats almost as good as the pile of mulch with the black PVC pipe layered in it and left to decompose.... free heat all winter ! HAHAHAHA

Ok test test test, started cell up at 5:30 this morning, going to run all day, so far I haven't seen any junk forming, this is good, after a good long run "all day" I'll take another sample and see if any of the antifreeze properties have been lost. also I upped the ratio of glycerin to 30% this mixture has no vinegar, just distilled water, glycerin, and Koolaid.

Bob,
You've got about 14 sqr yard of reflector there. So you should be good for about 10 Kwatt of heat into your focus point.
Track the sun with that thing and add a pipe or two and a little pump and you can be heat-rich.

Janmarch,
I take it you mean the Odeillo in the Pyrannes. (sic)
I also watched an item that is running on the BBC by James May showing a solar furnace run by a group in, I think, New Mexico that they are using to crack hydrogen for the making of petrol from CO2. The demo shows it burning through a mild steel plate in about eight seconds. Pretty impressive.
In California they are using parabolic mirrors to run Stirling engines. Santa Barbara I think.
Solar is the way to go if you get enough sun.

25%... thats 1/4 Glysern... thats a bunch ! 30% is even more !
...
I'ed need a quart of Glysern for my cell...where do you get that much ? drug stores sell it in pints at $5.00 a bottle

Yah.. Randy lives where the people grow webs between their toes like ducks do cuz its so wet!
....I lived north of where he does about 30 years ago in Port Tounsand Wa.... and I remember 3 sunny days... the rest were rainin'
it even snowed up there on me... something it hadn't done for 50 some odd years...
when I moved to Florida it snowed on me there too something it hasn't done there in 100 years
... so I gave up and moved to the mountians and at 5000ft I get snow all the time HAHAHA
...just as well ... it follows me where ever I go anyway ! HA!

You should all come to sunny Arizona if yo want sun. we didn't have enough sun to charge my battery bank once for almost 3 days and I paniced and ran the generator. Turns out I didn't have to since the sun came up the next day and I'd been fine. That Smack Booster sitting under my hood where the battery used to be gets up to 80 degrees by the time I get off work at 3pm. That's when it had gone down to 17 degrees overnite. It is a different story when the sun doesn't shine. Even when it gets to 15 degrees below 0 it will go up to over 50 degrees above 0 in the afternoon. I love it.

Hey Bob,
A couple issues back in popular mechanics they had a little article on a guy who took his old satelite dish and made it into a hot dog cooker by covering it with a bunch of little mirrors. He said it would cook a hot dog in a few seconds! How's that for redneck engineering?
