... I've changed my mind. It seems to me, that MOST of the elements of success in night-radiation are not within the control of a tinkerer. E.g., no can can...
HI Can anybody help me in developing an absorption cooling system. I want to know what kind of steel pipes to use (grade thickness) which can take 300 psi to...
I am wondering if anyone has played around with modifying an outdoor wood furnace for cooling applications. The wood furnace has a water capacity that is...
I think you should be looking at anhydrous ammonia and NOT aquaeous ammonia----there is a world of difference. These pressures will probably require schedule...
hi, are you thinking of something like the S.T.E.V.E.N. design? i thought about that one but gave up when i found out the cost of the ammonia. its very...
Hello folks from Ian Morrison in Australia morrisoi@... The question is asked about absorption refrigeration, the proportions of ammonia and water also...
Hi Bob I am not aware of STEVEN design. Can you let me know more on it as how can i find details on internet. I have been searching information on absorption...
... how can i find details on internet. ... to know is about icy ball project which is more in detail. ... me what you were planning and how much you were able...
the steven system is all the rage in homepower chat groups. http://homepower.com/files/solarice.pdf there is one commercial maker of this product. warning,...
To reduce cost of an intermittent solar refrigerator,using ethanol (alcohol) and activated charcoal would make it more readily available but the hong kong...
Been checking out the local appliance dealers to pick a chest freezer to convert to a chest refrigerator. Most have the "warm" coils just under the sheet metal...
Good questions. I hope someone here knows for sure but here are my suspicions. The manufacturers make what people buy -- good or not. People think they are...

Hi folks from Ian Morrison in Adelaide, Australia. The white goods appliance manufacturers compete with each other to offer the consumer goods "built to a...
Hi folks; I have a blueprint machine, which I am giving away. It is a GAF Print-Vac 190, which takes up to 50" paper. This is the ammonia type machine. It has...
The temp. of steam is diredtrly relative to the amount of pressure containing it. I.E. steam at 1000 psi would me many times hotter than steam at atmospheric...
My wife will probably scalp me but where in the Detroit area. I would be sending my Father from the down river area to pick up. Also are supplies still...
If I remember correctly--steam at 100psig is at a temp of 338 degrees F--You can work from there as one extra lb pressure will raise the temps approx 3 1/4...
Hi Tim; I think it has already been committed to someone. It is just a blueprint copier. It is not a CAD plotter. -Laren Corie- Integral Solar and Energy...
My point is That something less than 212 degrees (at atmosphric pressure) the ammonia boils out of solution. I am unsure what pressure an absorbtion type...
... Well, at first the floor-space consumption issue was the one that got to me......If one is having it built "for them" by a regular contractor, that house...
let me throw a wildcard on the table? if you're so concerned about the cost of refrigeration, why not re-analyze from first principles, your space requirement?...
That is actually an excellent idea, especially with the current crop of super-insulated coolers that are said to keep food cold for up to five days in hot...
... Is there a standard suggestion for the concentration of salt in the brine? I've been using frozen PET bottles of water as a supplement to ice in a cooler...
Yes: Add salt. Stir until dissolved. Repeat until no more will dissolve. 8:) The resulting brine may not fully freeze, depending upon your freezer--but it will...
That's a great 'wildcard' to expand the discussion. Your point about the sort of things we are going to such much trouble and expense to refrigerate is a good...
The most efficient refrigerator made today is the Sundanzer, and it is a heavily insulated chest type. They also have a freezer version. These are the best...
Given that there is much more energy stored in the freeze/thaw transition than in a few degrees change in temperature in the brine, wouldn't it be more...
