There is no law of diminishing returns. That’s an aphorism, not an actual scientific principle. If your power source can generate the power, it does so.
You don’t need to store an entire county’s power per day. Thats never been anyone’s goal, nor is it needed. You generate power for at least half of it, then continue to generate power with other green sources while also storing it.
You need to “restudy” the current state of battery tech and geothermal. There are huge arrays of different batteries being built now, and active 100+MW geothermal plants in operation, with more coming. The tech is here now, being built as we speak.

So you agree that solar + battery resolves 90-99% of power needs now at a drastically reduced cost and build time than nuclear today?
I expect that 10% will get much closer to 1% in the next decade with all the versatile battery/solar tech coming onboard, but to compensate for solar fluctuations, you use wind, you use hydro, and you use the new “dig anywhere” steady state geothermal that is also being brought online today. We can run more HVDC lines to connect various parts of the country. We are working on some now, but not enough. With a robust transmission system, solar gets 3hrs of “free” storage across our time zones.
Worst case? You burn green hydrogen you made with your excess solar capacity in retrofitted natgas plants.

You can quibble about battery engineering or focus on your original question, which is : can solar + battery tech do what nuclear does today, but faster and cheaper?
That is a clear yes.

My math assumes the sun shines for 12 hours/day, so you don’t need 24 hours storage since you produce power for 12 of it.
My math is drastically off though. Assuming that 12 hours of sun, you just need 2Gw production and 12gw of battery to supply 1gw during the day of solar, and 1gw during the night of solar, to match a 1gw nuclear plants output and “storage.”
Seeing as those recent projects put that nuclear output at 17bil dollars and a 14 year build time like, and they put the solar equivalent at roughly 14billion( 2 billion for solar and 12 billion for storage) with a 2 - 6 year build timeline, nuckear cannot complete with current solar/battery tech, much less advancing solar/battery tech.

Uptime is calculated by kWh, I.E How many kilowatts of power you can produce for how many hours.
So it’s flexible. If you have 4kw of battery, you can produce 1kw for 4hrs, or 2kw for 2hrs, 4kw for 1hr, etc.
Nuclear is steady state. If the reactor can generate 1gw, it can only generate 1gw, but for 24hrs.
So to match a 1gw nuclear plant, you need around 12gw of of storage, and 13gw of production.
This has come up before. See this comment where I break down the most recent utility scale nuclear and solar deployments in the US. The comentor above is right, and that doesn’t take into account huge strides in solar and battery tech we are currently making.

We discovered a banger like 200 years ago and have held on tight until eight about now with wind/solar/hydro.
Still going to be using their geothermal/fission/fusion for at least another 200 years though.

BMI is specifically not an amazing metric, for populations or individual people. The article goes into its flaws at length, but to summarize :
Its based entirely on white men, with no demographic data for women or POC. It also fails utterly to account for muscle, so it classifies many very fit people as obese.
Its only use is that it’s been in use for so long it can be used as a historical measurement to compare generations to each other.
Complicated math in the age of smartphones is a non issue. It’s also not required if you do the simple thing I discussed above.

Very usable without a computer once you do it once.
If you’re at a 5 on the scale “average to unhealthy” at 36 inches, you can put in 32 inches and find out that you’ll be “lean to average.”
So your goal is to lose 4 inches of stomach width, which you can measure with a 10 cent tailors tape.

Okay, so they got the game “mostly working” live? Well, that’s something I guess. That’s almost like a fully working game.
I guess that explains why the commentor above posted a pre-recorded video instead of the actual live video. It works against his case that the ge is basically done.

I’m just working off the video linked above. No video of the player, no commentary.
If they actually played it live, well bully for them. One point goes to star citizen.

This kills me, but its not as bad as the habit of new articles/print authors to switch between first and last names of the same person within a few sentences.
They will introduce Jeff Snoms, and then refer to them has “Jeff” and “Snoms” interchangeably for no discernable reason. It gets really maddening when they are doing it with 3 or 4 people, so suddenly the story has 2x as many characters involved.
- Comment on Goodwill is out of control 4 weeks ago:
You said earlier that goodwill “specifically markets itself as a thift store to help the working class and to help people get jobs.”
They certainly advertise the second part in that link, but I didn’t see anything about the first part, which is what you seem to mainly be upset about.
They are pretty up front about selling donated goods to pay for their charity work of job training. They don’t claim to be in operation to “help the working class get cheap goods.”
- Comment on Goodwill is out of control 4 weeks ago:
Habitat for humanity uses the exact model as goodwill for its retail charity stores.
You can disagree with Goodwill as a charity, but both are still thrift stores.
- Comment on Goodwill is out of control 4 weeks ago:
Yeah, looks like we don’t agree in most of the thread, but I’m 100% fucking with you there.
- Comment on Goodwill is out of control 4 weeks ago:
That’s how all charity thrift stores work. That’s how they have always worked. The retail sales power the charity. Goodwill, habitat for humanity, salvation army, on and on. I have some local ones that pay for animal shelters.
They all sell donated items to make money for the charity.
- Comment on Goodwill is out of control 4 weeks ago:
I’ve never gone to the goodwill.org page before today. That’s not very good marketing if that’s all they are doing.
My local one has a banner up for Halloween costumes, but that’s it. There are some generic “feel good” images of people being happy to work inside on the walls, but it’s not like it rotates or has ads or anything. Just generic cheerful “thank you’s.”
- Comment on Goodwill is out of control 4 weeks ago:
Thats pretty fucked up, but it also looks like they are moving away from using it:
As of September 1, 2024, only 10 of the 149 local Goodwills in the United States are reported on DOL’s list. Many of those organizations are in the process of transitioning away from using the certificate. GII does not hold a certificate, and we support local Goodwill leaders as they collaborate with people with disabilities, local employers and other service providers to create an array of community-based employment and other opportunities.

More like its $31.50 that charities can use to help working moms that scalpers pay to get a coat they can sell for $130.
- Comment on Goodwill is out of control 4 weeks ago:
Can you link some of these ads you’re talking about? I don’t really see any ads for them anywhere.
I don’t think they have ever hidden that they sell things that are donated, since they want people to donate. I don’t think they generally sell most things at market prices, especially notvfrom what I’ve seen. A $300 coat may be $35 dollars there, but that isn’t anywhere near “market” prices.
It sounds like you have specific issues with Goodwill, which is fine, but the above is how all retail charities work. The store prices are not the charity. The charity comes from the profits from the stores, so all retail charities are incentivized to make a profit in their stores. The fact that the prices are much less than market, and that they do some great environmental things as well is the extra postivie bits of retail chsrity like goodwill or habitat for humanity. If you don’t care to support the model, that’s fine, but that’s why they proce things like they do.
- Comment on Goodwill is out of control 4 weeks ago:
Okay, you misunderstand how retail charity works. These charities sell donated goods to generate revenue to fund their charity effort.
The “charity” isn’t the cheap goods inside the store. It’s using the profit they generate to run or give to that charity. This can be running food banks, animal shelters, jobs programs, etc. The more money they make, the more they can give to their causes.
Their social good works in 3 ways: provide that charity effort, provide inexpensive or less expensive goods to people, and act as free recycling centers for the environment.
