Seems that the breathing liguid, being a liquid (dense and heavy) is mechanically too hard to move in and out of your lungs. The substance, used to carry the oxygen, was originally developed to cool electrical systems in the Manhattan Project (!) and cools super computers, in fact. But our lungs are set up for moving gasses, and it's too much work to breathe the stuff. It's now being used to oxygenate pre-mature babies until their lungs develop further and they can breathe on their own, so it actually has some practical application (life-saving, for some) but won't work for diving. Thomas Shaffer, a physiologist at Temple Univ. in Philadelphia, is having success in his research and treatments using the liquid : perfluorochemical or PFC. Christopher A.
