"After early retirement, I had no idea where to use 30 years of know-how."
The idea

Semiconductor scrubber patents — verified precedent in the field
Catalytic oxidation from wastewater plants — different field, same function: breaking down toxins
Combined 3 cross-domain techs into a cleaning module; co-founded an environmental startup
