USES or LIQUID AIR MB. BOBRICK AND HIS LECTURES IN THE EAST He Tells the People the Commercial Value of Prof. Tripler's Great Discovery

G. A. Bobrick of this city, who Is actively identified with the Tripler Liquid Air company, has just returned from an extended eastern trip. Mr. Bobrick is an engineer and scientist, and during his absence has lectured on liquid air in Chicago, St. Louis and other cities with great success. The newspapers devoted a great deal 'of space to the lectures. The following is from the Chicago Tribune of March 16; Professor Bobrick partly disclosed a new scheme which Professor Charles E. Tripler of New York is working out. '.He says there is a "secondary process," by which liquid air can be made, and that, by milking use of the atmospheric pressure, the cost is reduced greatly. He stated that the plant he would install in California would contain a 135 horse-power engine, with which he could produce liquid air at a cost of 7 cents a gallon. I The experiments last night did not lack | excitement. Professor Bobrick made an ! explosive of alcohol and liquid air, which j he allowed to be passed to the audience. The men were smoking, and he told them I that a spark dropped in the tin dipper | would cause an explosion dangerous to life. | Me made an explosive many times more I powerful than nitro-glycerlne, and then I explained its advantages. If left 15 minutes, he said, it would become harmless, in mining it would be economical, because men could work directly after an explosion, whereas now it was sometimes half a day before the fumes cleared away. Then there would be no clanger from unexploded charges after 15 minutes. One of the most stupendous plans that Professor Bobrick suggests is the use of liquid air in bringing the power of Niagara Falls to Chicago. It is a singular combination of liquid air and electricity that will serve to transmit power. It has been discovered that if a copper wire isi cooled to 312 degrees below zero, Fahrenheit, the resistance to electricity is reduced from 100 ' per cent to 3 per cent. He proposed to lay ! a pipe, inside of which should be the! i copper wire. He would supply liquid air to ! the pipe, and at every 30 or 40 miles* have a | station to renew the evaporated liquid air. j | The evaporating liquid air coming from the I pipe can be used to run a compressor to ; supply the fresh liquid air. In! this way. he said, the power of Niagara Falls* could be brought to Chicago to a loss of but 3 per cent. Professor Bobrick believes in liquid air ;as a motive power for automobiles. He I says an automobile can be run at an expense of from one-half to one-third of a| i cent a mile. With liquid air he believes j I an engine weighing 35 pounds would run I I fin automobile, and that enough air couldf : be carri nl to drive it 1,000 miles. He showed j diagrams- to illustrate how the power of liquid air is controlled. It can be regulated almost perfectly. "I do not see why our hotel rooms should not be cooled in summer as well as heated in winter." said Professor Bobrick. "The ; air can be used twice, and, on the third exhaust, might be carried to the furnace, vfhere, having become almost pure oxygen. it would cause perfect combustion. "I believe that some day we will have 1 copper as hard as steel. Any engineer knows the value of hardened copper for enI gine bearings. It is a singular thing about copper that liquid air makes it soft, but ; when we take the copper and subject it to heat. It tempers like steel. "Another of the many things liquid air' will do is- to secure a perfect vacuum. The Incandescent bulb, as it is now, is imper- | feet. With a perfect vacuum we should i have a practically indestructible carbon I and a brighter light." Professor Bobrick is a Russian chemist, j and engineer, and, in connection with his: ; business in California, he became interested in liquid air. He has been in New J York studying the methods used by Professor Tripler. and was introduced last night by William A. .Vincent as being the; leading authority on the commercial value of liquid air.
