I'm glad I'm retiring. Electrical Engineering degrees. I dug ditches and laid pipe. Water runs down hill. OK, You got a degree in plumbing. Oh and keep your hands out of your mouth. How many engineers does it take to wire a new house?
I got a question. Why 50 or 60 hz and why 220-230, 100vac, 120vac, and why AC and DC? Isn't most solar DC? Maybe Edison was right. Water still runs down hill though.
