Making Ice Without Electricity

j-beda writes "Time Magazine is running an article telling us how Dave Williams is trying to make ice for third-world applications using the Hilsch-Ranque vortex-tube effect (first developed in 1930 by G.J. Ranque), where swirling air is split into hot and cold components." The method is horribly inefficient but Williams is hoping it could yield helpful results in areas where electricity is really not an option.

    If you can spin something at 1,000,000 RPM why not spin a copper coil inside a magnetic field and make electricity instead? Quite useful stuff I've heard.

      BINGO!!! We have a winner of the "Find the Logic Hole in the Seemingly Reasonable Idea" game!

      There's a reson why electicity is a freakin' universal component of modern societies people. It's EASY to produce, so easy that's it's just about goddamn trivial since there's dozens of different ways to go about it, and NONE of them involve ridiculously ineffcient and complex methods like "ice without electricity" does.

      Hell, why not work on "masturbation without enjoyment" too, that should be just as useful.

    The Romans used to make ice in the deserts of Palestine and North Africa. It seems to me they were around before electricity and Frigidaire.

    All right, but apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, a fresh water system, public health, and making ice without electricity, what have the Romans ever done for us?
