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.

    In conservative America, racists blame the victims.

    What does racism have to do with it? I wasn't looking at the color of any one's skin, you were. Now who's the racist?

    I was only considering their ignorance and idiocy at their decision to stay in a flood plain for a massive hurricane, when free busing was available to get them to higher ground.

    There's people that were victims (lost their homes), and people that were stupid (lost their lives by staying in their homes).

    And still I donated to the Red Cross immediately after the hurricane, and immediately before I was called an uncaring racist by most of the victims.
