Sounds like moving to PV for electricity generation is a risky option, since maybe margins won't be so high if they're made here in the US and the economics just don't work for manufacturing from scratch. Perhaps we should consider other options, like the magic rocks we can find in the woods that get really hot when you hold them close together. This way, we can simplify our supply chains and have a reliable supply of energy that doesn't rely on a hostile geopolitical rival, and doesn't require the costly transition of the grid that we'd need to do if we went all in on PV.
