That’s interesting. We got a swimming pool from walmart to help store water for the garden. The cover isn’t really much to write home about.
So you’re saying that the engineer’s Dad made a cover for the swimming pool? Was that directly over it or the roof of a room?
It was over it fairly high up so people were swimming in the pool with the cover above them. Engineer remembers swimming in the pool in winter due to the cover helping to keep out the cold (and this was in the north part of the US, maybe Illinois), keeping out the cold plus the dad made a heater to warm the water. He got parts and pieces from old equipment where he could find it and made a filter and the heater.
Remember his dad is the one who made a car that floated on air. Engineer got those smarts from that dad plus the mom was smart but the dad invented numerous things. Think I remember the dad worked at Sears and they gave him equipment that didn't work and he would fix it for them. People with that kind of mind are “different” and so is the engineer as he is one of “them”.
What gets me is he knows how things work that he has never seen before. I have a gold (not real gold) lighter with my name engraved on it that my husband gave me. I had lost it for a time and then I found it and was delighted except it didn't work. It was a Calibri and that is a fine lighter. I called the company and they don't fix the lighters but would give me a new one but they aren't like this one and I wanted the one I had so I didn't send it to them to get a new different one. Next time engineer was here, I asked him if he could look at it and do anything to it. He had it apart in a minute and cleaned the parts, put it back together and I'm using it now.
He has built a computer from scratch. One job he had was writing computer virus code and sending them to a naval base for their computer people to try to fix it so that virus couldn't hurt their system if they ever got it. He wrote computer viruses for a living. He is different just like his dad was different.
