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.

    Question, would companies like slashdot level traffice sent to their pages, especially if they are looking to get subscriptions?

    Could this be a new spam technique, attempting to get pay articles referred to by popular web sites?

    If I didn't know better i'd have sworn the pictures were coming from somewhere in Africa.

    Looking at other areas in the US, It's interesting to note just how much of America is really poor.

    Blanco was not slow to request tht a state of emergency be declared. However, she *was* slow in turning command and control of the relief effort over to FEMA - in fact, she has never done so. The former does not imply the latter. She also did not accept the offers of other states to send National Guard troops in to help keep order (something which the Feds can't do without invoking the Insurrection Act, which ought not be used for disasters).

    Both of these problems sound like bugs in the system - once the governer requests a federal state of emergency, FEMA should have all the power it needs to solve the problems encountered, but that's not how it works today. And it's worth noting that the DHS was *supposed* to be ironing out bugs exactly like this!
