Einstein Fridge Makes a Green Return

Use it to freezen Einstein's brain.Then it is really my mind protect my mind.

Ummm, the comment feature has quit working fr me, but I'll give it another try.

Rerigerators based on ammonia, and heat have been used in RVs and elsewhere for a long long time. They are however, somewhat fussy in their operation.

What if you are in a remote location with little sun? And heating butane into a gas could be considered by some to be very dangerous. And if the room is warm, will the water be chilled enough to continue the effect? Talk about hurdles and limitations. It would be simpler and have a more stable fridge if you just used solar panels to power a conventional fridge. Good luck on this one.

BTW, if you are using solar panels, then it's not "no-electricity." It would be considered "off-grid."

We use solar thermal collectors to heat our house in the winter. It would be nice to have an economical way to use the abundant excessive heat in the summer to cool it also.

To lilo:

You make the mistake of assuming that all solar power is electrical in nature. In this case, a solar collector would reflect the sun's rays at a heat exchanger that would drive the flow of fluids and gases in a closed system. So this would be solar power, but not electrical.

Also, this system would only need a small amount of butane to work properly, and the butane would be confined in a closed system of metal tubes so it would not be subject to any sources of ignition, making it safer than many of the other devices that use butane such as camping stoves and cigarette lighters. This system might not be very efficient, but it should be quite safe.

When I was a small child back in the 1952 my family got rid of our old "Ice Box" and bought a gas fired refrigerator. I remember it kept the food cool with no problems.

I also remember my mother and father discussing the purchase of an electric refrigerator over the dinner table a couple of years later because the price of gas had gone up and the electric refrigerator would be cheaper to operate.

Funny how some of the old "technology", electric automobles and gas fired refrigerators, are making a come back with a little tweaking with modern more up-to-date components.

ford2go is correct. many small applications like motor homes and other rv's are cooled by a refrigerator that is not driven by a compressor or freon. its driven by a small burner that uses anhydrous ammonia as its refrigerant. aka absorpition system. Also many industrial refrigeration facilities use ammonia as it refrigerant since its efficiancy is much greater then freon.

If more people did some history research they would find thousands of inventions that were by far more eco-friendly,than what persevered. In my opinion the only reason why they never made it into lasting household/everyday items was and still is economics. What ever is more profitable makes it, until the next large profit idea comes along.
A good example of this happened in the automotive industry with Baker Electrics, Owen Magnetic. It ran completely of a large magnet, made no pollutants and needed no external fuel or replacement batteries. Given it needed some improvements to make the vehicle last longer but what car made hasn't.
