2. All posts should contain a source (url) that is as reliable and unbiased as possible and must only contain one link.
Obvious right or left wing sources will be removed at the mods discretion. We have an actively updated blocklist, which you can see here: https://lemmy.world/post/2246130 if you feel like any website is missing, contact the mods. Supporting links can be added in comments or posted seperately but not to the post body.
3. No bots, spam or self-promotion.
Only approved bots, which follow the guidelines for bots set by the instance, are allowed.
4. Post titles should be the same as the article used as source.
Posts which titles don’t match the source won’t be removed, but the autoMod will notify you, and if your title misrepresents the original article, the post will be deleted. If the site changed their headline, the bot might still contact you, just ignore it, we won’t delete your post.
5. Only recent news is allowed.
Posts must be news from the most recent 30 days.
6. All posts must be news articles.
No opinion pieces, Listicles, editorials or celebrity gossip is allowed. All posts will be judged on a case-by-case basis.
7. No duplicate posts.
If a source you used was already posted by someone else, the autoMod will leave a message. Please remove your post if the autoMod is correct. If the post that matches your post is very old, we refer you to rule 5.

For copyright reasons, you are not allowed to copy an entire article into your post body. This is an instance wide rule, that is strictly enforced in this community.

So how do we get giant heat sinks in the water and harness the energy?
Heat's too diffuse to be useful. Entropy 🙃
Seriously I'm dumb but wouldn't it just be transfer of heat? I was joking btw but now I'm invested lol.
You need a temperature gradient to extract energy.
The water is still cooler than the atmosphere just less than usual.
It would be a few degrees warmer than deep ocean water, so you could maybe power one of those toy stirling engines with a heat sink near the surface and one deep down, but the amount of usable energy per m^2 would be milliwatts at best.
There is a temperature gradient from deep water to shallow, the sterling cycle is just not efficient enough to gain energy with a massive deep-shallow-deep heat pipe system.
That's usually the information I'm looking for.
Even if the concept works in theory, on practice it may not yield enough magnitude to be useful.
I had to look it up, it's dense and I have no idea how it works. I'm going back to art lol.
I see, thank you.
