In our area evaporative coolers are like magic. They use almost no energy but can bring down the room temp more than 15F.

  Alas, those only work in desert climates. Much of the world is relatively humid and "swamp coolers" are ineffective there.

    Yeah, here in UK my office at home is currently at 26C and 60% humidity - adding more with an evaporative cooler would do exactly nothing.
