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.

huh i hadn't heard of this one? I went to a dam last year and that's what the guide told us...

I think it's the physical size of the reservoir that is the limiting factor. You can't reasonable expand most reservoirs, but it's relatively easy to create new hydrogen/methane storage tanks.

Yes but pumped storage is about 80% round trip efficiency vs power to x which is barely touching 20% out of the lab. And power to X needs an epic fuckton of very clean water, which also isn’t easy to find.
