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.

Also, they claim it is safe due to lack of radiation. But ultrasonic can fuck shit up too. I mean ultrasonic is currently used to break up kidney stones, shear and fragment DNA (for NGS prep).

Good points, but to be fair, ultrasonic is currently used to break up kidney stones because it is safe to use it to do so.

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).

Submission + - Bill To Block Publishers From Killing Online Games Advances In California (arstechnica.com)

An anonymous reader writes: A bill focused on maintaining long-term playable access to online games has passed out of the California Assembly’s appropriations committee, setting up a floor vote by the full legislative body. The advancement is a major win for Stop Killing Games‘ grassroots game preservation movement and comes over the objections of industry lobbyists at the Entertainment Software Association. California’s Protect Our Games Act, as currently written, would require digital game publishers who cut off support for an online game to either provide a full refund to players or offer an updated version of the game “that enables its continued use independent of services controlled by the operator.” The act would also require publishers to notify players 60 days before the cessation of “services necessary for the ordinary use of the digital game.”

As currently amended, the act would not apply to completely free games and games offered “solely for the duration of [a] subscription. Any other game offered for sale in California on or after January 1, 2027, would be subject to the law if it passes. [...] In a formal statement of support for the bill sent to the California legislature, SKG wrote that “there is no other medium in which a product can be marketed and sold to a consumer and then ripped away without notice As live service games rise in popularity for game developers and gamers alike, end-of-life procedures are essential tools to ensure prolonged access to the games consumers pay to enjoy.”

The Entertainment Software Association, which helps represent the interests of major game publishers, publicly told the California Assembly last month that the bill misrepresents how modern game distribution actually works. “Consumers receive a license to access and use a game, not an unrestricted ownership interest in the underlying work,” the ESA wrote. The eventual shutdown of outdated or obsolete games is “a natural feature of modern software,” the group added, especially when that software requires online infrastructure maintenance. The ESA also said the bill would impose unreasonable expectations on publishers regarding licensing rights for music or IP rights, which are often negotiated on a time-limited basis. “A legal requirement to keep games playable indefinitely could place publishers in an impossible position—forcing them to renegotiate licenses indefinitely or alter games in ways that may not be legally or technically feasible,” they wrote.

Kevin Rose killed digg. He took what was good and ruined it.

Reddit embodied what was good about Digg and ran away with the market share.

As long as Reddit doesn't fuck with their algo, and try to pull a "Kevin Rose" (not unlike what Tik Tok just did) it will be ok.

Fuck digg, and fuck Kevin. Go back to making videos where you pretend you're "edgy" because you have a 40oz in a brown paper bag.

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.
