Comment Re:LFP for dummies (Score 1) 29

I wouldn't be surprised if we saw LFP replace most usages of lead acid batteries in the near future since the cell voltage is 3.2V nominal, and you can stack 4 cells to get a 12.8V battery, which would be a drop-in replacement for most lead acid applications.

This isn't true for multiple reasons. First and most importantly, full charge on a 4-cell LFP is 3.6 volts. That means full charge on a nominal 12V LFP is 14.4V. Charging voltage is therefore 14.6V or 14.8V and the details are handled by the BMS. Maximum charging current is also far higher than a six-cell flooded battery, which is fully charged at 12.6V, and where maximum safe charging voltage is about 2V over the current battery voltage. (Yes, some chargers do significantly more voltage — this is bad when done without per-cell temperature sensing which nobody does.) A flooded battery limits current, and charging systems take this into account. Dropping in a LFP might be fine, or it might cause the smoke to come out, and you have to understand the system to know which. Most alternators will burn themselves up, or at best, burn out the fusible link. On some vehicles that's easily replaced, but on most it's a harness repair. You cannot even reasonably charge lithium batteries with all solar controllers designed for flooded cells. Some of them are cheaply made enough that they will again burn themselves up, even cheaper MPPT units though it's mostly just PWM models.

Lithium batteries are great, but you cannot just drop them in to many applications. In others they will work OK, though most "intelligent" battery chargers not designed for them will only charge them to 80%, or will charge to 100% but charging slows to a trickle around 80%, because the charging voltage is incorrect.

then as long as you don't spend the cash in your account and keep it there for an emergency then the only way you can default on it is if you had an emergency that you had to spend the money.

Or you get hospitalized, or just really busy and forget, or you leave payoff to the last minute and the 'net is down, or whatever. This will happen to a percentage of people, so they will make a percentage on top of fees. It might not happen to you, but it definitely happens to people.

"What I don't want is a mass subpoena exposing answers I received. That's called privacy."

What you should have realized was that every interaction was being retained, and this meant it was out of your control.

"I can't imagine how anyone thinks that is funny. My problem is with the court- not the AI."

Your problem is that you're using AI with your brain turned off. Practically every slashdotter would laugh at your lack of realization that data, once out of your hands, is out of your control. There is no cloud, you are not Buddha, your data just went to someone else's server and it was always subject to subpoena and this is true of everything you ever did online. Nobody is throwing away data they have about you except as required by law, and they probably sold it first.

There is a long list of companies destroyed by MS and Gates from very early on in the 80s.

As if some open source devs never had dreams of replacing some commercial software.

Did those open source devs willfully abuse a monopoly position in basically every way possible, as the USDoJ found Microsoft did under Gates? Fuck your whataboutist billionaire worship cuckery.

I mean, there are no recent calculations there to indicate X amount of fuel is required, required algae feedstock, yields, areas, etc. It's from 1998.

Oh, I see that you didn't read it, as the study was literally about which algae is required. Since you don't seem to want to read it, let me explain: The primary takeaways are that it's not beneficial to try to choose a specific algae, and you can recapture up to 80% of the CO2 emissions of a fossil fuel power plant by bubbling the exhaust through algae ponds.

If you're too lazy to read the study, at least read the conclusions.
