Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
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.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
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.

It would be cool to see huge investments into battery storage. If we could create a battery that doesn't just leak energy from storing, we could generate power in one location and ship it out where it's needed. There could be remote energy production plants using geothermal or hydroelectric power that ship out these charged batteries to locations all over. It would let us better utilize resources instead of having to have cities anchored around these sources.
Or we could generate a ton of power all at once, store it and use it as needed rather having to have on demand energy production
Hell with better batteries even fossil fuels begin to be climate friendly since you could store the massive energy created and know you're using close to 100% of it.
Globally humanity already invests over 10 Billion dollars per year in advancing battery technology.
In order to build what you are talking about will almost certainly require real room temperature super conductors. We can get close, maybe, with the next generation of Aluminum-Air or Iron-Air batteries but this is big pimping. It's incredibly complicated and difficult.
It's like Fusion Power. We can see a future where we have it figured out and working but it's still some years, if not decades, away.
Allow me to share the most frustrating graph I have ever seen
We could just use energy to fill a big hole with water and put plastic wrap over top until we need to get the energy back then we pump it through a dam.
Then profit.
Problem solved
Moving batteries seems like a terribly inefficient way of replacing power lines.
Power lines would still mean we need energy on demand though wouldn't it. And if we can transport energy from an area like a huge solar array in the Sahara to Kazakhstan or China it would be better. I was just raising it as an off thought like maybe theres more ways to think about solving this problem than just building plants. What level of storage ability could we have that would let us build a large solar array in the Sahara to power Africa and Europe vs just building more plants. I think our end goal will be energy storage and like you brought up transport/transmission. I think that because I think we have energy production pretty well solved
Kind of an unconventional battery, but I've heard of solar and wind being used to pump water uphill into reservoirs and then released through a hydro plant when the sun/wind aren't shining/blowing. I'd be curious to know the amount of production lost from storing it this way.
I heard the loss comes from evaporation. Another cool idea I heard was using a mining cart. So its not practical but I think the idea is cook because I'm pretty science illiterate but it got me thinking about what a battery actually is. So you drag a mine cart up a hill with energy produced using renewable energy and then let it go down the hill and collect the stored energy with its motion. Technically there isn't anything like evaporation so you could store the mine cart up the hill with no energy loss.
Interesting. Didn't consider the evaporation. I imagine friction could effect the minecarts, but no idea to what degree. Some loss is gonna happen so matter what. If I'm understanding correctly, even nuclear, built away from population centers, will lose some power due to transmission distances.
