When u put water under extreme vacuum it freezes, so if you make a pvc water cell and pull an extreme vacuum on the cell with a valve or check valve you will have free ice.
No more refrigerators, no more ice to buy. will run a sterling engine.

...and what powers the vacuum pump?
Once the cell is under vacuum and held there, ice forever.
The trouble is that as soon as you start to use that COLD ICE by circulating a fluid in a pipe or tube adjacent to the ice, IT MELTS.
If you keep the cold ice ISOLATED by itself, it is of no value.
Sorry.

hmmm youve tried it eh :-\
I would like to see water the other way around, under about 1 million Earth Atmospheres. 8)
I dont believe it will melt, it may to a certain extent but as long as the vacuum is held it will still stay ice.
If you have tried it, I sure would like to see a vid. I will be checking it out as soon as I get the right compressor. The possibility's for this are endless ice chests that dont need ice refrigerators that dont need electricity air conditioners that only use a fan.
Now that the idea has been posted on a public forum it should be free right, no patents. The way it should be, minus the greed.

FirePiston - Generating High Temperature by Compressing Air in a Cylinder
The FirePiston glowingly demonstrates the rise in temperature when a fixed mass of gas is compressed. A piece of tinder (a bit of toilet tissue will do) inside a hollow transparent cylinder ignites when the contained air is compressed by a hand operated piston. This is the same process that ignites the fuel inside diesel engines � properly called compression-ignition engines. Includes various tinders with instructions on how to use them for good effects.
