For the past 30 years, American Steven Lurie Garrett, born in 1949, has divided his time between teaching graduate students and conducting advanced scientific research.
Most recently, he has served a year as science advisor to the U.S. State Department, a post he will hold part-time until 2014, while simultaneously resuming his position as a professor of acoustics at Pennsylvania State University.
Sixteen years after winning a Rolex Award, Garrett has not yet achieved his goal of creating a large-scale, commercial, CFC-free thermoacoustic refrigerator, the basis of his project, but he has made many inroads. One success includes a thermoacoustic chiller for Ben & Jerry’s, the environmentally concerned American ice cream company.
Garrett is now developing a large thermoacoustic chiller for supermarkets and will soon begin designing a high-efficiency domestic refrigerator/freezer. His team is also in the early stages of fabricating a thermoacoustic engine that will use waste heat from stoves to generate electricity.
