Real crisis like for example a long blizzard, or a hurricane that just passed near you?

Do tell us how your solar cells will perform in an actual crisis, rather than imagined one.

We're not even close. Lead-acid is way ahead in everything except energy density. You don't need to deep discharge if battery you get for the same cost has far more capacity than li-ion could ever hope to be, with far cheaper control electronics, is far more efficient and so on. As long as you don't care that it weighs far more than li-ion (which you don't in most homes), there is no reason to pick li-ion over VRLA battery.

We already have different chemistry batteries for use in those things. You have special kinds of lead-acid (typically valve-regulated lead acid for safety reasons) for home use and we're testing sodium-acid for utility use. And then you have flooded lead acid for cheapskates that don't care about maintenance intensity.

All of them utterly destroy li-ion in all relevant factors except one very important in mobile applications - weight per energy stored. That is why it doesn't make sense to use li-ion in applications where mobility and low weight are not key considerations.

Actually it seems more about the fact that "gigafactory" which was supposed to produce massive amounts of li-ion automotive batteries is being ready at the time when we have oil price that is less than half of one it was planned for.

As a result, EV sales are down, and factory needs alternative markets for production.

This is not common in the US? I've never lived in a house that didn't have a separate fuse board with separate fuses for kitchen stove, each individual room sockets and lights. Apartment building I live in now is built in the 70s and it has separate breaker for each of those - I just checked.

It sounds like elementary safety precaution.

No because lithium is an extremely common material on our planet. It's just extremely diluted. But if economic reasons existed, we could extract lithium from seawater.

Surprisingly modern coal doesn't. Automated burner controls that are controlled by modern accurate sensors in the burner and catalytic filters on exaust will get the main culprits (NOx, SO2, particulates) out of the exhaust very efficiently.

The only problem coal really can't overcome is CO2, because it's the natural by-product of clean burn of coal. And that doesn't "mess up your air". It just intensifies the greenhouse effect planet-wide.

Discharge rate. One of the main limitations on batteries is charge/discharge rate. Unlike supercapacitors, which can absorb and release large amounts of stored energy at rapid rate, batteries are severely limited in this aspect.

Yes you do.

Devil as usual is in the details. Inverter for solar differs from inverter needed for battery in the same way that say a heavy duty delivery truck and a sedan differ. There are some expensive ones that can do both, but cost reasons dictate that they are not used in favour of cheaper ones that fit solar installation only.

So your argument is that poor protection on OTHER machines is the problem?

Okay. Make a thread on the subject and stop shifting goalposts to jury-rig the argument to fit your "you must update or else you get raped, no really" agenda.

Have you ever realised that government actually does things that aren't top secret?

As in low level bureaucracy, crunching numbers needed to generate statistics, writing largely pointless reports that are necessary for archiving in case they are needed at a later date and so on?

I see those computers all the time. They're usually workstations sitting in places like watch booths of grassroot sports fields and such. They're rarely used, very old and completely irrelevant as they contain no data interesting for anyone. They're mostly there are browsing machines and something from which people involved can write daily report email and browse web for things like work shift schedules.

These computers are highly uninteresting for those behind zero day/targeted threats, as they would cost more to take over than any potential revenue you could secure from them for such an attacker.

You appear to be talking about security holes in third party software. How is microsoft responsible for it?

You are once again intentionally misunderstanding. As in claiming that "people riding in the vehicle perishing" is the same as "people riding in the vehicle which has a failed launch and kills people outside the vehicle by crashing on top of them".

XP SP2 changed so much, it was effectively a new OS by the time it came out if you want to go down that road. Especially by Apple PC OS standards.

Pretty much this. Most likely someone with a clue finally realised that as long as you have a working firewall and anti-virus that will block outside executables, your XP machine is quite safe from "omg internet viruses". Especially if like most computers in major organisation, it's also sitting behind a NAT.
