Aimed at the sun during ...I'll try to explain. Aimed at the sun during the day, the conical reflector collects infrared radiation and directs it to a focus to heat food, etc., but if the reflector is aimed into the dark night sky it works in reverse. Heat from the focus where the water sits radiates outward into the very cold night sky. Though the air around us feels pretty warm, if the sample at the focus is insulated from this warm air, then its heat radiates into the very cold heat sink of deep space. The temperature of space is near absolute zero, so it is a very effective heat sink if you minimize conductive heating from whatever supports the water pan, convection heating from local air, and radiant heating from nearby objects.<br /><br />Some tips. It is important not to have anything but clear dark sky in the field of view of the reflector. No buildings, trees, clouds, or the moon. These things are all warm relative to deep space and the reflector will collect the infrared radiation they emit and use it to warm the water. Don't use a glass cover since it is relatively opaque to infrared and will inhibit cooling. Polyethylene bags are relatively transparent to infrared and work well. Use a shallow water pan since a thin piece of ice freezes more quickly than a thick one. About 1/4"-1/2" of water in an aluminum pie pan works well. Place the pie pan on little wooden blocks to minimize conductive heat transfer from outside sources. Insulate under the pan along with several layers of crinkled aluminum foil to prevent radiant heating from the ground from heating the water. Double bag the pie plate with an air gap between the two to help insulate the ice sample as it freezes. You can expect about 20 deg F drop in temperature using this approach so you need ambient temperatures of 50F or below. I've often wondered if it would work at higher ambient temperatures if a bigger reflector is used. Someday I'll find out!<br />Nicusnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-2860631537182250492015-11-18T05:16:01.055-08:002015-11-18T05:16:01.055-08:00I'm surprised the amount of common sense stuff...I'm surprised the amount of common sense stuff I haven't learned in 50+ years.

But how much would a 2x4 insulated box with a bucket toilet, simple plumbing drains, a small woodburner and a couple solar panels on the roof to power your freezer cost if built on a trailer if you needed mobility. 2x4 only gives you R-13 if you use fiberglass but spray foam insulation doubles that. Have a couple windows on one side for solar gain and some insulating panels for nighttime and you could have an affordable shelter that beats the heck out of a tent. <br /><br />Kind of like your "solar shed" concept. Good article to reprint Lord Bison. I wish I didn't have code restrictions where I am. I could build really small and say screw the relatives. With enough solar mass to store some heat it could be very efficient if on a slab. Solar mass on a trailer is not efficient cause you want to be able to tow it. My old neighbor made a great camper out of a cargo trailer. Added insulation, windows and interior items. Yes, the cargo trailers are more expensive than a flat trailer but you get the structure included. Pretty stealth rig too.<br /><br />Like the modified freezer or a standard freezer and cooler concept.<br /><br /><br />Nightshifthttps://www.blogger.com/profile/16463940857394060911noreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-1354766825596128192015-11-16T20:58:16.927-08:002015-11-16T20:58:16.927-08:00I was referring more to being able to pick up and ...I was referring more to being able to pick up and take off at a moments notice Jim, for whatever reason one might have to do so.<br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-43943369543333967632015-11-16T20:55:08.153-08:002015-11-16T20:55:08.153-08:00“I completely agree on last part.

And it astounds me that anyone can ask a $1k plus for a flintlock musket? You might come across a cheaper gun or kit at a gun show, or at Track Of The Wolf, but other than that, expect to pay through the nose for one. I'm damn tempted just to go down to the hardware store and pick up a water pipe and piece of timber, and form my own stock and barrel. I can get the lock mechanism at Dixie, but such projects are really above my skill set, and best not attempted.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-32490020240362291682015-11-16T17:36:47.980-08:002015-11-16T17:36:47.980-08:00Hey Bison!

The solar "oven" was a cardboard cone covered with aluminum foil. I placed about 1/2" of water in a shallow aluminum pie pan at the focus, then enclosed the pie pan in double Ziploc bags to eliminate air convection around the water pan and to add an air insulation barrier around the inner bag. Daytime temperatures were around 95 degrees F, but night time temperatures dropped to around 50. Radiating heat into the clear night sky froze the water solid. I built 6 of these little "ovens" and was able to produce about 5 lb of ice per night which was collected in the morning and loaded into an ice chest. There was always frozen ice remaining the next morning when the next batch of ice was added.<br /><br />I now live in coastal Washington where I seldom have clear night skies, but for minions living where clear skies are common with night time temperatures below about 50 deg F, this is a very inexpensive way to keep things refrigerated off grid.Nicusnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-1523382695710721912015-11-16T17:36:45.117-08:002015-11-16T17:36:45.117-08:00You are halfway there.

A parking space for a trailer or motorhome could be dug in so that the floor is a few feet below grade (bottom of windows at-grade? over-dig and fill with gravel for good drainage? if on a slope, dig so water drains downhill) sheltering the "gap" of air under the vehicle and some of the sides. An upgrade for later would be a low carport/woodshed over the hole to put the vehicle out of the weather/snowdrifts. Solar panels could be mounted on the angle-optimized roof. I would dig the hole oriented east-west to better control the shading/not-shading on the southern side of the RV. 4' chain link fence enclosing the curtilage of the home (repel tumbleweeds and some medium critters who eat your herb garden). <br /><br />How much extra tax would a "farm vehicle shelter" add? <br /><br />pdxr13Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-80742206028651683572015-11-16T17:22:50.326-08:002015-11-16T17:22:50.326-08:00Build a 2x4 and 1/2" plywood platform on 6&qu...Build a 2x4 and 1/2" plywood platform on 6" castors for the freezer/fridge to sit on. Don't forget the 1x4 around the edge to keep the device from sliding off, then you can wheel the thing outside when it's real cold and save some coin/power in the process. I'm going to put one of those together next summer.<br /><br />Last winter I installed a ProCom propane wall mounted 10,000 btuh heater here in my office and I'm very happy with it. I don't know how efficient it is because it's connected to our 400 gal tank that heats the house. The unit cost $125 at Menards + $25 for the hook up fittings. It's radiant heat so it takes about 2 weeks to settle in and during that period I am constantly turning the temperature down a few degrees every couple days as everything in here also warms up and traps the heat. By Jan I expect to have the temp backed down to about 60 and it will still seem warmer than that in here. Radiant heat is the way to go, much more comfortable and cost efficient. I have a 3'x3' window over my desk that I keep cracked slightly all the time to keep some fresh air rotating around. I also have a smoke detector and a CO2 detector. 2nd winter so far and no issues at all. I'm thinking about buying and restoring an old canned ham travel trailer and I'll put closed cell foam on the envelope and a Procom on the wall.

But if you can buy it immediately after the land, park it on the land and stay in it for one year saving rent of $500/month in 6 months you could have half the money you need to excavate your permanent structure; AND have a 'guest house"/ bug out shelter/ extra storage / or nice weather extra space to live in. <br />Or, if is just you , you could go cheaper and stay in a tent, or you can commute from somewhere to be able to work on you land at least weekly (better to do daily).

That's actually my plan for refrigeration. I figure that in the root cellar with much lower temperatures to start, the ice will hold up much longer. The pioneers would cut blocks of ice from the local ponds, and then place them in ice houses covered with sawdust. The ice would actually hold all through the summer, providing them with ice during the hottest months. An icebox in a earth sheltered home should be pretty close to the same thing.<br /><br />You would want to use the big blocks of ice, as opposed to the cubes. You can route the run off water to a tank for other use. You could even form your own ice block moulds and make you own ice for some additional self sufficiency. <br /><br /><br /><br />Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2686829448547770092.post-336132428696495322015-11-16T08:57:20.665-08:002015-11-16T08:57:20.665-08:00use the book "Sunshine to Dollars" and m...use the book "Sunshine to Dollars" and make an ice maker.. for a couple hundred watts during the day you can make a big block of ice quickly, then just use a super insulated cooler.
