1000% agree. But to Lemmy’s credit, I found a greate niche community of linux and programming enthusiasts, plus I’ve noticed I run into Europeans more in the wild on here.
I think the fediverse has it’s benefits. Still not a full replacement. Truthfully I don’t think it will ever be, those niche communities will always end up being hosted where it suits them best.
Specifically, I think the abilty to make hydrogren from renewable resources at large-scale will change everything. Hydrogen fuel cells are more space efficient, and require less toxic manufacturing, when compared to current renewable energy generation and storage methods. If hydrogen is seen as cheaper or more green than other power sources, it will change the market completely.
Hydrogen generation is also an active research area, and just this year they’ve have some promising results for renewable hydrogen.
You have any sources for this? A quick glance at wikipedia says that hydrogen ICE has about the same energy efficiency as gasoline, if the engine is properly tuned.
