Comment Ford, too. (Score 2) 160

I bought a Ford F-150 XLT (the full-hybrid pickup) and was very disappointed to find that several of the features (Including Blue Cruise and navigation) were subscription-based with an initial free period of a year or so.

Other than that the vehicle is fantastic - but was very pricey when I bought it, so having to pay over and over for the features was a very annoying surprise. (They quit working rather than quit updating when the subscriptions run out.)

If you just disable the REST API, you can avoid most of the issues.

On my site which runs Gentoo, I've already been able to apply the update, but on the other one where I have to run Debian I am of course still waiting for the new version to be made available! Disabling the REST API has enabled me to keep that site live while I wait.

Well, yes. For many years, presidential candidates, both Democratic and Republican, referred to the United States as "the indispensible nation". And my reaction was always, "Doesn't that mean the US is a single point of failure for civilization?"

We are currently performing an experiment which addresses this question: can the US enjoy the benefits of soft power without the cost? That's the whole point of obeying *norms*. No individual force is going to punish you if you are treacherous, mercurial, foul-mouthed, disrespectful and generally unpredictable. Everyone will punish you.

I think an inevitable cost of this experiment will be that the world will decide that the US can't be a single point of failure for global democracy any longer. In many ways, that's something that will be good for us. But it's also going to cost us in painful ways. When the world decides to move away from the dollar as the international reserve currency, you will see both inflation and higher interest rates on everything from credit cards to mortgages, to business loans that will offset the export advantages. We will need *more* business investment to shift the economy to producing low value goods again, so the transition will be rocky.

It's a trade off: you get abundant free energy to run the server, with extreme constraints on cooling because your server is running in the most perfect Thermos bottle ever.

Others are taking the opposite tack: undersea data centers for abundant free cooling at the expense of having to get the power down to your servers.

If had to bet on which one is more practial, I'd go with undersea servers. Build them off the coast of Chile, run cables out from batery-backed solar plants in the Atacama desert.

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.

Comment Re:Amazon is corrupt! (Score 4, Insightful) 22

I think it may be evidence that Amazon has a shitty corporate culture that squeezes every penny it can out its employees.

Corruption can happen anywhere, but it's more likely to happen in totalitarian cultures where people feel like the system is rigged anyway. That's why countries like Russia and China have corruption problems. But I suspect the same feelings of me vs. the system occur in a capitalist enterprise like Amazon where employees are governed by dystopian, rigid, computerized metrics.

The restrictions are a mix of reasonable nuisance management and paranoia about who is flying drones, what they can do, and chain of custody.

Beijing proper is a city with a population density of over 21,000 / km^2 -- so you can imagine the chaos if any tech enthusiast resident could fly a drone without a permit. Except for a couple of free zones in the outer boroughs, New York City restricts drone launcing and landings within the city to flights with a permit and flight plan, because otherwise the sky would be black with drones. Many cities -- both red and blue -- have zone restrictions for drone flights, and those currently hosting World Cup matches have tightened them for the duration of the tournament.

Comment How long (Score 1) 155

I've seen the Veritasium video and my question at the time was, and remains, how long could it keep this up for? Producing a lot of power for a few seconds is one thing, maintaining it for any significant length of time is quite another when you only have sunlight to rely on.

Perhaps these satellites have much bigger solar arrays than GPS satellites. Perhaps they have huge batteries to allow them to maintain the required level of jamming for an extended period during a conflict.

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 Where would the lead go if not burned? (Score 1) 108

If the wood isn't burned then where would the lead go instead?

We already use all the wood we need for applications in building, furniture etc. The wood that gets burned in stoves generally isn't good enough for those applications anyway. So, if it isn't burned then presumably it will sit around and slowly rot away. So what happens to the lead then? Does it go back into the soil? Will it leach into rivers and streams to mostly end up in the sea? Perhaps bacteria and fungi which attack the wood will release it into the air anyway?

I've no idea of the answers to this, but it seems to me that if you are going to worry about lead being released by burning then you have to at least explain how that compares with the none burning alternative.
