Where does the energy come from to lift water by osmosis? (feddit.uk)

For example in a tree, the water is lifted from the high concentration in the soil to the low concentration higher up in the tree. But at the end of that process the water has been elevated, which should take energy (=mgh), but it seems like it kind of gets lifted for free without spending any energy?

Similarly, dipping a paper towel into a bowl of water, the water "climbs" the towel (by capillary action?) and absorbs upwards, meaning the water was lifted upwards (so gained potential energy) seemingly for free?

Thanks. From the linked discussion, it does solve a legitimate problem - I had noticed that entire comment branches could be lost if a parent comment was deleted or removed. That was also pretty bad, so I'm glad there's been progress there.

Honestly I think reddit's approach is correct: when I delete my comment, other see that a comment existed here once, but not what it said or who wrote it, and it's no longer interactive. And, deleting it doesn't affect child comments.

Fair, I was hoping it'd be something you could configure. Hopefully this improves with Lemmy in the future then.

Lol, seems we can also vote on and reply to comments after they've been deleted. That seems silly

I know that. But at least that's not really publicly listed for anyone to load from my home server in the original comment thread. And that's beyond the server host's control anyway; it's completely within the server host's control to decide to delete something properly on request or not, so choosing to not delete it is just weird.

Rather than having some control over my comment in the source thread on the source server, I now have zero control at all. That's not a good user experience.

When I "delete" a comment, all it does is replace the text with "deleted by creator". It doesn't even hide my username. This is different from previous behaviour where the comment was entirely removed from the public view.

I should be in control of my comment. If I want to delete it then it should be entirely removed - at least from the public view. I don't want to make comments knowing that I'm permenantly etching my username into the stone of the thread forever with no ability to delete it. I'm highly put off from engaging now that I can't reliably delete what I write.

Being able to undo the deletion is fine but the undo really should only last 1h or maybe 24h before the comment is properly deleted.
