@feld @tk @akorenchkin So in your world, the post-BEV world will be powered by something with even worse energy density...
I'll believe in synfuel powered ICE cars before that. And because #hydrogen is truly sustainable, it is guaranteed to play a role. People who doubt this are rejecting obvious real-world advancements while simultaneously imagining fantastical leaps in highly speculative technology. It is unlikely, and more than anything else just a sign of wishful thinking.
