How Mirrors Could Solve our Energy Problem

It's nice that Toyota sponsored this but they are one of the companies that most actively lobbies the US government to oppose vehicle electrification and emission controls.   They've spent millions or billions on their hydrogen fuel cell technology instead of battery tech and they're behind their competitors.  They supported the EPA emissions rollback under the Trump administration in 2019, joining GM and Chrysler (Stellantis), while Ford and every other car maker supported the California effort to keep it at the higher levels.  So glad they're here to support you, and maybe hydrogen fuel cells could be an option for energy storage although that would be incredibly inefficient, but I think it needs some context.
