Comment Foccused ultrasound but yes. (Score 1) 37

microwave labotomy ... We just put the machine against your head here for a bit and those bad urges go away, all better.

Another poster mentioned that it's actually focussed ultrasound.

Still sounds like breaking a piece of a system by stirring the brain with a knife (lobotomy) or burning it out with heat (cauterization), electricity (electroshock) or mechanical shock (blow to the head) - just carefully focused without (substantial) damage to other parts of the brain or its casing.

Ultrasonic destruction of a piece of the brain's reward/punishment/desire/avoidance mechanism rather than persistent unwanted fat.

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 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.

Submission + - NY AG Letitia James is suing Valve (cbsnews.com)

DesScorp writes: James is going after Valve on gambling charges, stating that loot boxes are predatory, especially for underage gamers:

"This loot box model that Valve has developed—charging an individual for a chance to win something of value based on luck alone—is quintessential gambling, prohibited under New York's Constitution and Penal Law," the complaint says. In one of the games, the process even resembles a slot machine, according James. Since the prizes in the loot boxes are determined randomly in accordance with odds set by Valve, James alleges, that effectively makes Valve an online casino. "Valve, a video game developer, has made billions of dollars by letting children and adults illegally gamble for the chance to win valuable virtual prizes," James posted on social media. "These features are addictive and harmful. That's why I'm suing to stop Valve's unlawful conduct and protect New Yorkers."

Probably not for long. You may as well buy that no-name TV made in Vietnam now, because name brands have ceased to mean anything in this space. Just about everyone followed RCA and GE and Philco, who all stopped making sets in the 80's, and made all their TV money licensing their names to cheap Asian third parties. There hasn't been a real RCA TV since 1986.

Oh the day has come when people look at vile, despicable anti-capitalist actions in cities and think "lets do the same thing in farmlands".

Zoning laws, not high taxes, are the reason people are fleeing California.

Uh, it's both, and crime too.

The lack of multifamily housing (condos and apartment buildings) is why housing got so expensive.

Housing got expensive because California become like New York City: A place where the young want to be because its "the center of it all", which creates luxury pricing conditions for everything, not just housing. As packed as LA and the Bay Area have become, you're only going to get more apartments by seizing single family homes by eminent domain and tearing them down. That's not America, and even in California, that'll get you a fucking riot. Go on, try it and see.

We need to eliminate car dependency and give people a choice of transportation. Freedom of mobility includes freedom to not travel by automobile. Side benefits include less pollution.

Bullshit. You already have that in cities. People have a variety of choices. Every big city in the US has both bus and light rail systems with very few exceptions (Cincinnati, for one). EVERY city of medium size on up has a bus system. What you really want is to force your post title on people: no cars at all. Your whole aim has nothing to do with "choice".

The West is not prepared for the impact AI is having on employment, and will continue to have for decades to come. Some people are burying their heads, but it won't save them.

Next we'll be refurbishing old software to run on machines with lower specs.

Some of us are kind of doing that already by running old OS's in VirtualBox, and then running old but useful abandonware for personal tasks on those OS's. It's pretty fun and there's an ocean of useful and interesting software out there.... especially from the 90's. You just have to be careful about where you get it from to avoid the malware aspect. But there are some reliable sites. And it's pretty fascinating using software that my dad used. We're definitely in a weird time.
