A real engineer would have understood how the national grid works, understood that the entire country is not under cloud for a week, that solar panels work on cloudy days, that grid wind generation and grid storage will be available and that we will be producing a surplus of electricity for things like water desalination and hydrogen production.
All because electricity generation will be soooooo cheap.
A real engineer wouldn't have made the dopey claim about 20 PowerWalls.
I know plenty of engineers. One good thing about them is that they have a good education level which enables them to investigate and understand challenges outside of their field of expertise.
Every time you make one of your hair brained claims such as " it's just like building a highway " or this latest one about " 20 PowerWalls s", it shows how uneducated you really are. You're fooling no one except yourself.
Here's a couple of real, qualified engineers. You're not an engineer's bootlace, old girl.
