    HOUSTON, TEXAS -- The latest thing in experimental spaceware is undergoing test at NASA's Manned Spacecraft Center at Houston, Texas.

    The suit, a water-cooled undergarment, was tested for the feasibility of using it over the present method of air-cooling.

    This experimental undergarment, to be worn under a spacesuit, resembles a pair of "long johns" with plastic tubing sewn into it. It would be used to keep body temperature down and prevent dehydration under conditions of extreme heat.

    With this type of cooling, only two pounds of water and a small 12 ounce circulation pump need be carried by the Astronaut into space.

    Water enters the undergarment at 45 degrees, passes through the maze of 40 tiny plastic tubes that cover the body, and is warmed to about 55 degrees by the body heat before it leaves the suit and returns to be recooled.

    Derek Burton, Human Engineering Expert of the Royal Aircraft Establishment in England, who made the first basic design said in a technical report that, "---the suit could find many uses other than space--such as firefighters, steelmill workers, miners, and underwater divers."
    Prior to testing, electrodes are fastened to the surface of the skin. These electrodes transmit pulse rats, temperature on the skin surface, and inner body heat.

    After suiting up, the test subject is then placed on a threadmill which is set for two miles an hour. Under normal walking conditions this is slow, but with the 29 pound space-suit on this is exhausting. The treadmill rate simulates a high work-rate to test the suits capability of removing up to 2,000 B.T.U.'s per hour, which is the equivalent of 500 calories of heat.

    The large panel board that records the testing data is nicknamed the "Comfort Board" by the testing engineers, as it controls waters cooling, air cooling, humidifies or dehumidifies air, and is equipped with a heat exchanger in order to obtain the desired temperature.
