Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Because there's no demand for it. Currently production is very dirty but the engine itself is green as it gets. As the demand shoots up government can and probably will stimulate green production of hyrdogen. Point is, once you have hydrogen car there's no upgrade path needed anymore. Initial ICE engines were of poor efficiency but it got better. But we have to pick technology which can scale with demand. Batteries are simply not it, especially when it comes to big transporters like boats and trains. You can't use batteries on those. Even trucks are problematic as battery weight significantly reduces amount of cargo.
