I guess my most impactful project was a microprocessor-based weather station for siting wind energy systems and fruit frost prediction in the early 1980s. Turned out that one of my stations, being used by a frost predictor, was across the street from a rural drainage ditch in which a young child was discovered face down in the water. The frost predictor faxed temperature profiles for the previous several hours to the hospital, where doctors determined the child could be revived. She was.
