We can actually store energy from the grid. Not as inexpensive as generating it, but not unreasonable either. Most new solar/wind installs are now coming online with approximately 4 hours of battery backup. Currently the shortfall is d

Yes. As Apple puts it here[0]: > You complete one charge cycle when you’ve used (discharged) an amount that equals 100% of your battery’s capacity — but not necessarily all from one charge. For instance, you might use 75% of your battery

> suburbs typically cost less per sq foot than dense areas. What?
184.
by N1H1L 5y ago
Yes - but you are never really cycling all the way. Draining them down completely and filling them all the way up. Rather they are often smoothing out power supply.

Yeah. And for big power banks, there are several options beyond Li-ion. There are sodium, iron and magnesium chemistries for one. Compressed air storage is another option, that is quite cheap and scales extremely well. The one being built b

Again wrong. Singapore is building HVDC lines from Australia as we speak. We have been building underwater cables for a very long time (100+ years now) so it's pretty much a solved problem currently. Deep sea oil rigs have existed for

True. However, I see the same story now repeating for Arizona too. Intel, TSMC are all opening fabs there - but where is the water?

I am curious. There may very well be patterns. Like that recent article where an algorithm could guess the ethnicity of patients from X-rays, such patterns may very well be present in driving

You don't need to clear trees and build roads for offshore wind. Nobody is denying that nuclear is concentrated. However, this concentration also misses one step - when calculating areal requirements you should also calculate land nee

True. However NYC also has a huge population and enormous energy footprint. The population of all those countries combined is around 5 million, less than a third of NYC. I specifically chose NYC, as it's one of the most densely populat

One thing is pretty sure - we need to overbuild solar and wind. The total annual energy consumption in the US is around 15 PWh. Notably, the per capita energy consumption has essentially remained flat for four decades now. This energy consu

by N1H1L 5y ago
Overbuilding solar and wind have been long suggested. But your insistence that batteries will only provide power for a few minutes is honestly not backed up by any data.

Define short periods. Also gas lines froze more than turbines did BTW at Texas, just FYI. Very few conventional sources can also backstop 10GW of demand mismatch. Which is why having a national grid is so much better, power from Arizona can

Batteries easily last a decade now. LFP chemistries easily will do 1000+ cycles. Also 24 hours is a huge amount - you actually don't need more than that, especially if you have offshore wind in your mix, as they blow pretty much all th

For 250 turbines, based on your own links we need 444 sq km. That's like half the area of the whole of New York City. Not a small country. So based on offshore capacity factors, an area of NYC will generate 500 16 0.5 = 4000MW contin

Used car batteries are much, much cheaper. So as more BEVs come on road, that's obviously one way forward. Also $100/kWh is today. However, given how rapidly costs have declined over the past three decades, nothing suggests that t

by N1H1L 5y ago
Why not? It's a matter of cost ultimately. A gigawatt-hour of battery storage is US$100 million.

by N1H1L 5y ago
Batteries are already there. We can get them at $100/kWh now. Also generally these wind turbines cost a million US$ per MW, so this turbine is around US$16 million. A day of storage at 50% capacity factor for this would then cost US$ 1

Along with animals we also forget about fungi and insects. Trees communicate between themselves through forest wide fungal networks. And that's the biggest problem of pesticide driven monoculture farming - you destroy all of that compl

Yeah this whole credit score conversation going on in this thread is very weird. Has nobody here bought a car or applied for a loan ever? And how is Bitcoin going to tell whether you default on loans or not?

> Building more hospitals is a long-term process. Training medical personnel is a long-term process. Emergency measures intended to bridge the gap are untenable politically, and people are dying because of it. Thousands of them per day.

It could be simply from a human being to their dog, who chases a deer and passes it on.

My major background is in electron microscopy. Eindhoven is also a massively important microscopy center. This is because Philips used to build great TEMs once upon a time, which was spun out as Philips Electron Optics in the mid 90s. That

Is this some sort of a post-truth joke? If you are claiming something is the best, then without any comparable metrics across systems we are in the Twilight zone.
