I worked for a paint company for about 10 years back in the ’80s. I know that titanium oxide was the basic ingredient for producing white paint. It was also very expensive. This discovery will help to protect structures like yacht against UV radiation that destroys most varnish and epoxy-based protection.
BTW, at that time I developed one of the first AI applications for choosing the right coating protection in most situations. The AI application was a hardcoded ‘Expert System’ which was more popular in those days than current Neural Network. The application was programmed in C, M4, and Informix among other things, and was running under SCO Xenix. We had an interface developed on Tandy Model 100 that would allow users to connect to the Expert System via modem at 300 and 1200 bauds. One of the users was even able to connect to the apps from a boat in the Arctic via satellite. Pretty good for that time.
