Generally speaking, solar panels aren’t optimized for near-constant traveling.
Do they mean it can’t get a net positive amount of energy produced while driving it? Because, relativistically I don’t see why near constant speed is different from being near stationary for solar panels.
I remember telling people it’s possible and having a whole bunch of online folk tell me how Stephen Wang from Princeton said there was a 98% chance that Democrats would win.
Nate Silver went from being congratulated for his predictions to getting criticized for mentioning that there were correlated errors which could easily result in a Republican president. It was interesting because Silver wasn’t even predicting a Republican victory just a 40% chance it could happen.
