...clear water without heating it. But when the light strikes the opaque carbon, the carbon heats almost instantly and in turn heats the water, which turns to steam. The steam escapes through a hole in the top of the sphere, whence it could be piped to operate a steam piston, and so an engine...
...seems necessary that every field of concentration in college must have its elimentary course. Music 1a serves that purpose in music and it is only thanks to Mr. Piston's careful and interesting presentation of the material that it escapes being the frightful bore that German A. French 2, and similar courses are. For anyone who is really interested in music and who is willing to do a little, extra work this course should be skipped...
Steam, or water vapor, operates a piston or turbine by the fall in its temperature. The higher the vapor is heated, the greater the pressure which must be controlled and the work the steam can do. Engineer Emmet sought a material whose vapor could carry great quantities of heat at relatively low pressures. He found mercury the best. It boils at 675° F., instead of at 212° F. for water. At 884° F. pressure is only 70 lbs. on a gauge, at 1,000° F. only 180 lbs. Those pressures are sufficient to run turbines. After...
