the film and play. I was surprised by several of Eli’s responses – Chesen, practices psychiatry in Lincoln, Nebraska. Given his profession, I am never surprised by his keen perception of others. He is politically and culturally-sophisticated, and smart as a whip.” Inventions Chesen has produced several energy innovations such as transformerless low voltage, halogen light fixtures and an air conditioner (refrigerant mediated) swimming pool heater, which takes waste air conditioner heat and transfers it into the family swimming pool providing, in some latitudes, 100% of desirable pool heating at an energy cost of zero. The crude prototype of this device appeared in Popular Science Magazine in 1978 and has since been improved and operates automatically in its current incarnation. Subsequent to the Popular Science article Chesen was granted $10,000 from the United States Department of Energy to perfect the device. One version of Chesen's pool heating devices incorporates principles of mammalian physiology (known as a counter-current multiplier system).
