- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 3 hours ago:
China has been doing them in around 7 years from groundbreaking to grid connection and is trying to get that down to 5 years with their bailong power plant as they are developing an experienced work force and actually have experience making the parts
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 3 hours ago:
According to the link you listed an AP1000 costs $66/MWh where as from the ember report that’s linked in this article solar plus storage for 97% uptime cost $104/MWh in a sunny city. In Washington DC it would cost $124 and only be able to maintain 81%. I still stand by even with the higher cost that solar + storage is a better option in places like Arizona, Nevada, Southern California ,etc. but nuclear is not as much of the high cost boogeyman as you are making it out to be

Next two? After you mentioned it I tried googling and can’t find anything about current projections for new AP1000s at vogtle.
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 19 hours ago:
Yes, what I am saying is that cost is being shown for nuclear and not shown for solar due to using an intentionally small window of time. It’s like comparing an ICE to an EV and talking about the refueling costs of gas and treating electricity like it’s free.

Batteries and panels degrade over time. So if you are trying to maintain a specific amount of power you would need to keep investing in order to maintain the same amount of power generation
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 20 hours ago:
They had to switch halfway through which is what added the cost that’s not a realistic cost per reactor
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 20 hours ago:
Vogtle’s numbers are incredibly biased considering they made an entire design and then had to redo it halfway through that’s not a realistic cost that can be expected for future projects. We also have vogtles design be approved now so that new plants can be built for a fraction of the cost. Also where did you see they did amortization of solar?

My understanding of that graph is how do you flatten peak energy demands, Birmingham is flat and throughout the year because you have some parts of the year where you need very little battery capacity and other parts where you need a lot. Las Vegas basically always needs a lot because of how hot it gets they end up with huge amounts of peak energy usage
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 1 day ago:
That is the main criticism of nuclear, it should hopefully get better with Westinghouse’s AP1000 receiving full approval and being built all across China so as long as we continue to use the same design it can start to be mass produced instead of making all the parts as one offs that are much more expensive and time consuming
- Comment on Solar + Battery (covering 97% of demand) is now cheaper than coal and nuclear 1 day ago:
As others have said this is for Las Vegas which receives wayyy more sun than the average place. But the other misleading part is they looked at 20 years which is close to the life cycle for solar/batteries and not even half the life of nuclear

Is it really “opt in” or is the opt in only for them to give you the information that they collect? I haven’t read through any terms of service for it but my assumption is they are already selling that data

If you are interested I can try and find the article on it but a few years ago an article came out where they were able to use wifi signals with enough accuracy that they could see a password that you were typing on your keyboard!!
But basically they use the way the wifi signal bounce off things to make an image in much the same way that echo location works

Then you don’t get elected…
What I find funny is I have the exact opposite opinion that the left spends more time trying to appeal to voters than actually communicate what they are trying to do. So we end up with things like 250B to boost American manufacturing that got completely ignored

That’s why it’s important to be able to convey your message so people know what you are trying to accomplish with the 2000 page bill

People regularly vote against their own interests
- Comment on In old movies, it's only creepy rich people who have cameras in their house watching everything. Now everybody's creepy. 2 weeks ago:
Only people I know with internal cameras use them to check on pets when they aren’t home and put them in common areas, so if they were hacked it could still aide a burglar but if the feed was hacked it wouldn’t show them naked
- Comment on AGI achieved 🤖 3 weeks ago:
Which is why it doesn’t search within an instant and it uses a bunch of energy and needs to rely on evaporative cooling to stop overheating the servers
- Comment on AGI achieved 🤖 3 weeks ago:
Computers for all intents are purposes have perfect recall so since it was trained on a large data set it would have much better intelligence. But in reality what we consider intelligence is extrapolating from existing knowledge which is what “AI” has shown to be pretty shit at
- Comment on New fuel cell could enable electric aviation 4 weeks ago:
The amount of CO2 in the atmosphere is not actually very high in terms of actual percentage it represents less than half a percent so the reaction would not neutralize all the sodium hydroxide. Also trace amounts of sodium hydroxide is a bit of an overstatement if we have jetliners using 100MW while flying

And how do you keep the wood from being exposed to moisture without petroleum derivatives? Like technically it is possible but to build enough homes to that standard for even 1/1000 of the population is unreasonable
- Comment on When you see danger coming 1 month ago:
We also cover wood in hydrocarbons to stop it from being broken down, if a bacteria can break down long hydrocarbon chains we are kind of fucked
- Comment on Not difficult to understand 1 month ago:
It’s a chance for you to explain what you were doing. If you spent that time taking time off between jobs because a job fell through, you got laid off, you quit spontaneously, etc those are all very rational things that an employer may want to know.
It’s up there with innocent questions like “where did you work before here”, and “do you have reliable transportation “

He’s in charge of the Catholic Church why is it a surprise that he follows the status quo of the Catholic Church?
- Comment on Not difficult to understand 1 month ago:
You can say something like “I was attending to personal matters” that still gives no information but doesn’t come off as rude to what could be an innocent question

- Comment on Not difficult to understand 1 month ago:
It depends on the context if you say you had an NDA and can’t elaborate at all on the details that’s a clear red flag as most NDAs you can at least give the context of what it is about I.e. specific job processes, witnesses an event, etc.
If you say you worked for X company but can’t talk about the details of your work because of an NDA then that’s fine but they might call your old employer to verify you did really work there.
- Comment on Vitamin technology has advanced so much over the years 1 month ago:
Vitamins are barely regulated and don’t have to pass the standard of “generally recognized as safe and effective”. Because of that we don’t even have a ton of data on the effectiveness of multivitamins, but one of the things that we do know is most of the vitamins are just pissed out because they need cofactors to be properly absorbed. If you truly can’t get nutrients from a healthy diet then they are better than nothing but healthy diet is still the number one priority.
Doctors sometimes recommend them because “they can’t hurt” but that doesn’t mean they are actually helpful
