Electric planes could be in service as soon as 20 26, which is not that far away. The energy density of batteries isn't quite good enough yet to lift all that weight of the battery off and then fly with the power generatod from the battery. But as battery teckin proves, maybe that's a projection that will make this possible by 20 26. And eventually we see a world where we've wiped out the amount of omissions coming from cars. There still leaves boats orains. We got to get to those too.
