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.

Alright its later today so heres how renewable energy as a baseline supply works. We actually already have a working example of it, hydro electric. Renewable energy thats used as baseline. When you think energy storage i think most people think of batteries, but theyre mostly suited for mobile energy storage, like cars and handheld devices. For utility power we have much more scalable, and simpler energy storage. For hydroelectric, they take excess electricity generated, and power pumps to pump the water back uphill, to use for later demand. Its physical energy storage. You can power a motor to lift a weight and pulley system with excess energy, then run it in reverse as a generator for demand. This is basic engineering, and its as scalable as you need it.
I understand pumped storage well. The problem with it is the required size of the reservoirs and the availability of suitable locations.
Pumped storage as it stands in the UK is really very useful for managing dips and spikes in power demand but unfortunately far, far short of being able to get us through a day or two of no wind.
Right, pumped storage hydro electric was an example of renewable electricity being baseline load. I gave a different suggestion for wind and solar storage if you dont have a good location for pumped storage.
I honestly think the weight lifting and dropping idea is pipe dream stuff. It's good on a black board but near impossible to implement practically in real life.
Can you imagine how much stored weight we'd need to cover the energy demands of a nation given a few days of no wind?
You need to ask yourself why, if these ideas are so great, have they not already been implemented.
Oh god lifting and dropping a weight near impossible to implement? You cant mean that, you cant be that simple minded that you cant imagine an electric motor winding a chain hooked up to a pulley lifting a stone block. What part of this process is unfathomable for you?
It is already implemented, i gave you an example of it being implemented, its an everyday fact of life that we use electricity to lift enough weight uphill to cover times of demand surpassing immediate supply for massive regions.
If we're going to talk to eachother like we're cunts;
I wish I could return to a time where I was so naive, the world was a magical place!
I'll ask again since you avoided the question. Do you have any idea how much lifted weight would be required to power a nation through a few days of no wind?!
Hint: A metric shit tonne would not even be a scratch on the required amount. Where are you going to source that sort of weight, leave alone infrastructure required to repeatedly lift and lower it?
I'll tell you once again, I'm well aware of hydro pumped storage, its abilities and its short comings. I work as an electrician on a hydro scheme, FFS, you dumb twat.
A weight you could lift and drop to power your own house alone through a few days of no power in itself would be an extremely impressive system and you want to power every house in the nation and all its industry with that concept? It's time to get a grip on reality and share what ever drug you're on with me because its obviously some really good shit.
I will reiterate, that it is an amount of weight lifted that we already achieve, everyday to power entire utility areas. And Im tired of these strawmen. You know what would be an even more impressive feat? Building a nuclear plant to power your own house alone. Building one power plant to power the entire nation, from any source. We're not building to power one home, we're not building to power the entire nation at once.
