Cedar Rapids Gazette (Newspaper) - February 27, 1974, Cedar Rapids, Iowa Scientist Suggests Microwave Power lly Hit hard I’. Jones MILWAUKIE (DIM) II people nit! really concerned about conserving energy, a professor of electrical engineering says, they should examine more closely lilt* potential uses of microwaves. Dr. Thomas K. Ishii, of Marquette university, said the extremely short radio waves can be used to dry clothes just as they are used to cook food. They can also be used to transmit raw |>ower without Wirt! as well as a person’s voice. Melt Snow Islip said in an interview that man could also use microwaves to melt snow on his sidewalks or heat water in his home. Mic rowoves, with wave lengths between infra red t a diation and television radio waves, were first noticed in the 1920s, when radio operators began searching for more frequencies, Ishii said. He said the age of microwaves opened in 1927 with the development of a good magnetron, a vacuum tube which generates microwaves. Today, Ishii and others are working on a system which would transmit power from one point to another without wire, lh' proposed orbiting solar power .stations in 1967, the year he pioneered in tile development of a microwave-drive motor. Ishii said power generating satellites could be launched today but their electricity would cost three to IO times as much as current from power plants on earth. The biggest problem is converting microwaves into electricity and Ishii is trying to build a microwave motor big enough to drive a generator. Solar Panels “This is just one possibility,” he said. Microwaves could be used to heat water to drive a steam turbine but panels of solar cells would have to cover six square miles to produce enough energy to generate one million watts. I “We just actually scratched the surface,” Ishii said. “There are lots of innovations and improvements that have to be I done.” His microwave motor looks like a simple coil of wire. It is driven by the interaction between microwave current and a microwave magnetic field. The concept is so simple, Ishii said, I he wonders why it was not thought of earlier. Ishii said manufacturers might also look into other areas, The C edar Rapids Gazette: Wed., Feb. 27, 1974 5A particularly the kitchen, and apply what they see to appliances in the laundry. He said a microwave clothes dryer would save time and energy, like a, microwave oven. Ishii said microwave dryers,' like ovens, would be expensive at first. Hut he said the price would probably drop as the market expanded. He said a microwave dryer would be no more dangerous than a conventional dryer. “If the nation is very serious about conserving energy, I think that we have to look at microwave heating very seriously,” Ishii said. 20 YEARS AGO — Thomas L.
