Comment Re:I want to see inexpensive plugin hybrids but .. (Score 1) 135

You might want to read up on how current hybrid vehicles actually work, 'cause it seems you have more than one misconception going on.

I have. For instance, my latest vehicle is the Ford F-159 XLT,, the full-hybrid model of the F-series pickup truck line. Power train is:
  - 6 cylinder dual-turbo engine. (runs low power but approoximately doubles output when a lot is needed.)
  - 47 HP motor-generator "pancake" on the engine side of the ttransmission, to scavenge / return power to./from a 1.5 kWhr lithium battery.
  - 10-speed automatic transmission, working with the lithium battery;s main alternator to fine-tune match the engine/mogen to the current driving situation. Max power of engine plus hybrid mogen; 430 hp.
  - full four wheel drive.

So it's primarily a gas-engine power train with an electric-car motor mechanically coupled to the engine shaft. Many other hybrids, from the venerable prius onward, are similar, with plug-in variants having a big scavaging/peaking battery good for pure electric operation of tens of miles rather than a minute or so and a wall-powered charger added.

What I'm looking for is essentially a pure electric - totally electronic "transmission" consisting of alternator(s) between the batteries and the motor(s), plus a tiny engine-generator able to burn gas and feed some teens of KW of charging power into the batteries when running down the road or parked near it.
 

Comment cobalt chemistry, not so nice. (Score 1) 115

Do the Waymo batteries use one of the lithium chemistries including cobalt, or a non-cobalt chemistry such as lithium iron phosphate?

Cobalt chemistries have a higher power/weight and energy/weight ratio, which made them the go-to chemistries for vehicle batteries. But they also produce oxygen when the cells overheat, leading to an unextinguishable runaway fire hazard: A burning cell makes enough heat to ignite the adjacent cells, so the whole assembly of them goes. Bad enough when it's a car's worth, but a disaster if it's a shipping-container sized module of a utility energy storage site. (And even worse when the site is a building full of racks, which someone had "protected" from fire with water-spraying, equipment-shorting system, so the whole site burns up, as happened recently with one in California creating a toxic mess.)

That's why purpose-built stationary lithium energy systems use non-cobalt chemistries - heavier, but a shorted cell just kills itself without getting hot enough to light off its neighbors.

I want to see inexpensive plugin hybrids.

But not like the current ones, which are primarily an engine/tranny powertrain with a motor/generator + small battery for scavenging downhill/braking energy for later accelleration/uphill/cruise/power-boost.

I want ones that are primarily a battery-electric with a small aux engine-generator (say 15-20 HP range), big enough to power crusing with a bit left over for gradually charging. That would let you range-extend by the size of your gas tank plus fillups (i.e. indefinitely if only gas is available) or go from battery empty to back on the road in a couple tens of minutes.

The backup engine would only run at max-efficiency speed and could use an atkins-like cycle (see "liquid piston engine") to get the max power out of the fuel. Most operation would use power-grid charging (when available and cheaper than fuel).

Comment Some numbers (Score 1) 27

The greater metropolitan area of Mexico City uses around 7.5 billion kg (liters) of water per day.
(25,000,000 people using 300 liters)
Lithium is about 100 parts per billion in sea water.
So if you desalinated enough water to supply Mexico city, and sorted off all of lithium, that would be 750 kg per day, or 270 tonnes per year.
Annual global lithium production is about 290,000 tonnes per year.

Desalinate water for all of Mexico city, add an extra 0.1% to lithium production.

Color me unimpressed.

Comment Dumped Grok over this (Score -1) 72

Grok was constantly say it was doing something that it had ZERO ability to, and I kept calling it out and it kept apologizing and then immediately doing it again.

As a guy who spend 5 figures a year on Ai, the last thing I want is that. I know Claude and ChatGPT also do it, but Grok was doing it CONSTANTLY.

Comment Look up "human shields" (Score 1) 255

And a douche bag of a president who drops bombs next to schools and kills 135 kids . Should resign on the spot for that.

Look up "human shields", the practice of siting military targets among (or in or under) large collections of non-military civilians, in order to deter strikes against them or produce propaganda claims of atrocities when they're attacked anyhow.

In such situations the fault for the "collateral damage" is assigned to the side that set up the arrangement, not the side that hit it.

Nevertheless, it should be noted that the US has been trying very hard to use precision munitions and extreme military intelligence to take out military targets with as little harm to the innocents they're embedded among as possible, with impressive success. Compare the amount of collateral damage in this war to any of those conducted in the 20th century.

Comment Comparing your accent to claimed residence history (Score 1) 255

He's doing the bare minimum sniff test of verifying that *you* are the guy whose name is on the bookings and not someone sneaking in on someone else's name who can't even pronounce the name on your fake id.

At least in the case of people claiming to be returning citizens I've been told that they're comparing your accent to your claimed residence (or residence history).

Different words are acquired at different ages, and many are pronounced with regional variations. An expert can talk to you for a few minutes and come up with a pretty good age-map of where you lived as you grew up. An agent with a modicum of training can detect a mismatch between how you pronounce certain words and your claimed residence and pass you through quickly or keep you around and drill more deeply. (If you now live in an area with a regional accent wildly different from where you grew up it can help to answer a where-do-you-reside question with "Footown, but I grew up in Barstate".)

I presume they are doing something similar, though no doubt with lower resolution, on the world-wide level for visitors from other countries.

Comment Re:Constitution? (Score 0) 135

I don't disagree. Personally I think the Federal government got too powerful after the civil war & we really don't even have the same type of government that the founders envisioned.

I'd be somewhat in favor of an Article 5 convention so long as any changes had to be subject to a vote like the President is elected. The Electoral Collage system is absolutely brilliant & gives the individual vote maximum power because a handful of voters can change the outcome of an entire election. If people really want something they need to get out and vote. If you stay home you can't complain if the other side doesn't.

Anyway, good luck to us all.

Well you're not wrong. Most people forget the 9th & 10th amendments and what they actually say.

9. The enumeration in the Constitution of certain rights shall not be construed to deny or disparage others retained by the people.
        - Basically saying, "just because we listed a few specific Rights here, that doesn't mean those are the only ones The People have."

10. The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people.
        - The Federal Government is not permitted to just assume new powers because we didn't specifically restrict it here. If it's not specifically listed in this document the government cannot do it.

How far afield of these rules has the Federal strayed? How much longer will The People tolerate it?

Wait, what?

The Constitution is a restriction on the powers of the Federal Government, not on Anthropic. The Federal Government does have the ability to "regulate commerce" under what is called the Commerce Clause in Article 1, Section 8, Clause 3.

I'm not sure what particular law(s) c/would apply here - if any - however I'm certain various courts might have to render a judgement.
