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 ebikes are dangerous! (Score 1) 244

Speaking as a motorcycle rider, ebikes are dangerous. Not because of the bike but because of the riders. They often don't wear safety gear, they don't follow traffic laws, and many bikes top out at 70-80kph. It took considerable effort to get my Class M. A bike going that fast should require licensing and safety courses and helmet laws. Most people don't realize they can squid out on the road on an ebike just like you will on a motorcycle without proper gear.

Lunar "soil" is essentially neutral, just needs some additives. Conversely, Martian "soil" is actually poisonous. Additives alone aren't sufficient to get things to grow in it, you need to remove the poisonous parts first.

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.

And it would be pretty hypocritical to try and stop it now after we've been insisting that people who work with their hands accept the fact that technology might cost them their jobs for hundreds of years. But yes, the question of whether we are going to use the resulting productivity gains to improve the general welfare or to further empower the wealthy is a big one. I'm hoping this time we can get it right.

Comment Ohh Now It's Your Job It's Different? (Score 2) 94

Lots of this anger seems to stem from the fear that AI will take the jobs of programmers and artists. And while I sympathize (it might destroy my vocation as well) for centuries we've been asking craftspeople and those who do manual labor to accept the fact that their careers can be upended in the name of economic progress. The original sabotage is (supposedly) a term that arose out of the anger about automatic looms hundreds of years ago. Now the same kind of automation that took jobs from people who worked with their hands is coming for white collar jobs and it would be pretty hypocritical to suddenly call a halt now.

But maybe this time we can actually try and make the economic benefits work for the welfare of society as a whole, e.g., by using taxes to distribute the benefits.

What your missing is the fact that lots of people use it responsibly and no one notices. If you are using it right, e.g., to help you write a bunch of documents (it helped immeasurably with the right tone and suggesting phrases for all the paperwork for my wife's tenure application) no one notices because you use it responsibly and don't just copy paste whatever it does. Exactly *because* people are so hostile, everyone using it in a responsible way doesn't get noticed and all you hear about are the idiots who copy paste it without thinking.

For instance, if you look closely you can see all sorts of great uses on youtube where suddenly channels have great animations helping explain what they are talking about (e.g. for continental drift or engine parts) but those aren't noticed and everyone complains about the slop.
