"The world we live in today is merely a stepping stone to tomorrow, with countless challenging questions left for scientists and engineers to answer." THAT MESSAGE of opportunity oppor-tunity was presented to local students when General Motors national assembly program. Previews of Progress, appeared ap-peared at Bountiful, Millcreek, Centerville Jr. Highs and Woods Cross High. The non-commercial show Seeks to encourage more student interest in science, engineering, and related vocational careers. It was presented live and in nontechnical non-technical language by General Motors lecturers. A HIGHLIGHT of the 45 minute program was a unique laser projector demons! ration. ra-tion. A laser beam was used to translate the sounds we hear into visual patterns of light which danced on a screen before the audience. The GM representatives also al-so explained how the energy of the sun can be converted int electricity by running a model of the Surveyor Lunar Roving Vehicle on solar cells. A 300-watt 300-watt lamp, simulating the sun's ravs. powered the Moon Rover across an undulating table top surface. STUDENTS ALSO saw two fast-paced demonstrations which il lust rate recent developments toward solving water and air pollution problems. First, the lecturers showed progress being made to clean up water used in an industnal process. They combined two common com-mon manufacturing pollutants pollu-tants to produce clean water and to eliminate the pollutants in one mutually beneficial operation. THEN STUDENTS viewed a cutaway model of a catalytic converter, a device used to reduce automobile related exhaust pollutants. Based on extensive research and engineering. en-gineering. GM believes the catalytic converter is the best choice of alternatives at this time for meeting 1975 federal requirements because it reduces emissions of pollutants pollu-tants while also permitting improvements in fuel economy and dnveability of automobiles. A unique way to move heavy loads with little physical effort was illustrated by an "air bearing" platform. A small vacuum cleaner type motor provided a thin film of air under three large circular pads supporting the platform.
