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.

So y’all just pissing in cherrios today?
This is a brand new, opt in interoperability tool between 2 small-ish social networks. No shit its not heavily used yet.
What exactly are you complaining about ewv? That someone else did something cool you don’t care about?
- Comment on Use 'Bridgy Fed' to connect Mastodon and Bluesky 14 hours ago:
Interoperability removes power from closed gardens. It makes the platform itself way less relevant.
“Bending over backwards” is how you undermine bluesky in favor of mastadon. We should 100% be doing it as much as possible.

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.
- Comment on Why BlueSky Isn’t the Alternative to X (Formerly Twitter) You’re Looking For — and Why Mastodon Is the Better Choice Over X, Threads, and BlueSky 2 days ago:
Email was invented in 1983.
It was revolutionary, the utter example of a “killer app” that had people and businesses running out to buy computers just to replace paper memos. You setup your mail server to hook into that stunning ecosystem of near inatant communication from across the world.
Now there are 6,000,000,000 “killer” apps you can install in seconds from your pocket computer. I can hit “install” and be talking face to face with a stranger in Singapore in 30 seconds, all from with easy, no or low effort walled gardens.
Federation was and is a reasonable way to host things, but comparing it to email is a misnomer. People dealt with federation because they had to. If gmail has existed in 1983, no one would have had their own federated servers. Hell, AOL tried to choke the internet itself, including email, to death and almost succeeded in the early 90s because it was an “all in one” solution. They had aol only webpages and everything.

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.

Expected yield for the Swiss is apparently 2% of the total consumption for the nation just with their tracks alone.
Thats not a lot by itself, but add a few innovative solutions together an you hit double digits in powering a nation. That’s very valuable.

- Comment on In 4 years, US power grid increased battery storage to the equivalent of 20 nuclear reactors | The Optimist Daily 2 weeks ago:
That’s a solid critique. We can math it out more.
So each 1.2GW reactor works out to be 17bil. Time to build still looks like 14 years, as both were started on the same time frame, and only one is fully online now, but we will give it a pass.
For 17bil in nuclear, you get 1.2GW production and 1.2GW “storage” for 24hrs after 14 years.
So for 17bil in solar/battery, you get 4.8GW production, and 2.85gw storage for 4hrs. Having that huge storage in batteries is more flexible than nuclear, so you can provide that 2.85gw for 4 hr, or 1.425 for 8hrs, or 712MW for 16hrs. If we are kind to solar and say the sun is down for 12hrs out of every 24, that means the storage lines up with nuclear.
So off the cuff, for the same price, you get 4x the overall power generation and the same storage, and you can build it much, much faster. I don’t think a 7.5x larger solar array will take 7.5x longer to build, but I would expect maybe 6 years instead of 2.
So, worst case, instead of nuclear, you can build solar+ battery farms that produces 4x the power, have the same steady baseline nuclear, that will take 1/2 as long.
- Comment on In 4 years, US power grid increased battery storage to the equivalent of 20 nuclear reactors | The Optimist Daily 2 weeks ago:
The 2 most recent reactors built in the US, the Vogtle reactors in Georgia, took 14 years at 34 billion dollars. They produce 2.4GW of power together.
For comparison, a 1.4 solar/battery plant opened in because this year. It took 2 years from funding to finished construction, and cost 2 billion dollars.

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.
