So the only way to do this is to make water. So which method will Google be using to make water? Will they use:

- Desalinization? Doubt it. - Distillation from air? Doubt it. - Combine hydrogen and oxygen gases? Yea, nope.

So how will they make 120% of the water they consume? The article talks about misnamed conservation efforts. That's not making water.

One common way is treating municipal wastewater. This doesn't "create" water, but it does make available a water supply that wasn't previously.

"recycled treated wastewater"? I can only imagine they would have the mother of all filtration systems so that a tiny chunk of "whatever" doesn't clog up a tiny water line. And, the chemicals they have to add to prevent corrosion and water scale and all that pollutes the water used enough that it might not be reclaimable without specialized filtration.

I think such systems are generally dual-loop. There's the loop that directly cools all of the equipment, which is full of pure (might even be distilled) water that circulates but is not consumed, then that water goes through a heat exchanger in a much larger supply of treated wastewater. So the wastewater doesn't get close to sensitive equipment and doesn't run through tiny pipes.

1. The immunity ruling, plus

2. Absolute authority over the executive branch, plus

3. The unlimited pardon power.

This is an interesting analysis, and I don't necessarily disagree with the points made. I would only point out that the Immunity ruling was in July, 2024 while Biden was President, and he absolutely utilized #2 and #3 and arguably #1. Suggesting that this is a Trump-only problem is disingenuous.

I don't think I ever suggested that this was a Trump-only problem... indeed I specifically highlighted at the end that conservatives should worry greatly about what an unlimited liberal president will do, and I pointed out at the beginning that presidents have been pushing the boundaries since Nixon, at least.

Regarding your claims about Biden... bringing him up is kind of a non-sequiteur. As the other commenter pointed out, Biden very much followed the traditional path with respect to treating the independent federal agencies as independent. Do you have any counterexamples? As for #3, Biden did abuse the pardon power and I wish he hadn't done it, but as far as I know there is zero evidence that he did it to protect people from prosecution for illegal acts that he ordered.

Finally, on #1: Yes, the ruling happened during the Biden administration, but the ruling was entirely about Trump. I'd go so far as to say that if Biden had been the subject of the case, the conservative justices would have ruled the other way.

While Trump didn't initiate the move towards a more powerful executive, if he achieves status as king-in-all-but-name, he'll be the one that did 90% of it.

Drones are specifically the male bees. Most bees are not drones.

That's not what I said. I said that the word "drone", as in a mindless unthinking being, is derived from drones, as in male bees. I did not say "all bees are drone bees".

And an individual bee has limited memory. They even forget which hive they are from after a while if they don't return to it.

You are confusing "forgetting" with "disruption".

Bees have both a geospatial "mental map" (based on landmarks, the sun, etc) and a chemical fingerprint (they recognize their nestmates' smell). Concerning their geospatial memory, not only is it not poor, the main problem with it is that it's too stubborn. If you move a hive 20 meters away, the bees will fly back to the same empty location where their hive used to be and wait there. They don't adapt well to change because they have a long-term memory of "the hive was here".

If a beekeeper wants to move a hive, they have to trigger an "orientation flight" to get the bees to learn the new location (this typically involves locking them inside their hive for several days to disrupt their routine). During an orientation flight, the bees will learn the new hive location, and then they'll subbornly remember that location long-term, even if you move the hive again.

As for recognizing their nestmates, this is again based on smell. A bee being isolated for days or weeks will still be recognized by guard bees at the entrance and welcomed in. However, guards will sometimes let in bees that don't belong to that hive as well, if e.g. they're passive and laden with pollen and nectar; they haven't "forgotten" their scent, they're just "forgiving" of mistakes if there's a reward to be had (bees sometimes make navigation errors, esp. if all nest boxes are similar in shape/colour or due to wind, and enter the wrong hive)

I'll repeat: bees do NOT have a short memory. This is a myth. It's not true. The very example you gave is actually an example of bee memory being too rigid.

Already, the battery are too depleted to be used for what they were intended; what happens when they can't even shore up the power grid by a significant amount. If they were perfectly usable--they'd still be in the cabs.

Not at all.

Car batteries have to have high storage to weight ratios. A reduced-capacity battery holds less power but still weighs just as much.

But weight doesn't matter for grid storage. If the batteries only have half as much capacity, just stack up twice as many of them. And in fact it's not a case of "half capacity". I'd bet Waymo retires them when they get to 80-90% of capacity, because reduced capacity means more time spent charging and less time spent working. If the grid storage system gets a battery with 80% of its original capacity, it can likely use that battery for decades before it has to be retired and recycled.

And, of course, lithium ion batteries are highly recyclable, so there's no reason not to expect them to be recycled when they're finally taken out of service in 2060 or so.

batteries in EV's driven by consumers last 15-20 years: https://www.evconnect.com/blog...

That's not really correct, though. The batteries aren't worn out or unusable after 15-20 years... they just have maybe 15-20% less capacity than when they were new. So a battery that provided 400 miles of range, now only provides maybe 320 miles. So it becomes a question of how much range reduction the owner is willing to tolerate.

I bought a Nissan Leaf in 2011. The early model Leafs were something of an outlier because they lacked a thermal management system for their batteries and they had a very small battery, both of which caused them to suffer much more severe degradation than basically all other EV models. My 2011 now has about 70% of its original range, and that original range was only about 80 miles with a good tailwind. So now it can only go about 50 miles on a full charge. In the winter, that drops to about 40 miles... less if you use the heater.

Is the Leaf's battery so degraded as to be useless? Depends on your use case. For many use cases the Leaf's battery was too short-ranged to be useful when it was brand new. For a typical commuter, though... it was fine when it was new, and now it's marginal to insufficient unless you can charge at work.

As it happens, my son -- a college student -- still drives it daily to and from school and work. In the summer it can get him to school and work and home, without charging (he charges it from a wall outlet at his apartment). In the winter, he has to charge either at school or at work. Both have chargers (proper L2 charger at school; wall outlet at work -- but it's enough).

I wouldn't put up with that at my stage in life, but there are plenty of people who would. Heck, in college I drove a car with an unreliable starter; I always parked on an incline so I could start it by rolling and popping the clutch. This is even more true of vehicles that start with a larger range, say 300 miles, and more reasonable degradation. Your 300 mile-range car may become a 250 mile-range car over the course of 20 years of use. More likely, if you're the sort who buys a new car, you'll keep it for a few years and then sell it or pass it to someone else when it has lost only a few miles of range, but there's no reason not to expect it will stay in service for 20, even 30 years... mostly likely until it's in an accident or has other issues unrelated to the battery that aren't worth fixing.

It's IMHO amazingly impressive how dense information can be stored within neural networks. Even a comparably tiny LLM can store more information than the human brain, despite the brain's theoretical storage being far higher due to its vast number of connections (ANNs are better at information density, we're better at learning from limited datasets). The tiny LLM will crush humans at a quiz in virtually anything except said human's particular areas of expertise. Storing information as a superposition of states across a large number of neurons and connections (whether we're talking artificial or biological) is an immensely space-efficient way to do so, and the human mind is nowhere near the limits of information storage capability.

There is no technical reason why a given organism, such as a bee, could not achieve far denser information representations in order to be able to do more with its limited neural capacity (though there are always tradeoffs). One of the reasons that ANNs learn slower-but-denser is the use of a very low learning rate with a very large amount of data that covers the same topic from many different angles, giving the weights ample time to explore different possible circuits in parallel and seeing which ones predict reality the best ("learn everything all at once" vs. "learn this thing NOW"). Bees aren't tasked with learning anywhere nearly as diverse things as a human is and spend all day doing the same basic job (the same information "from different angles"), so it seems quite possible that their greater "information specialization" as they go about their day may be able to lead to denser representations of said information.

BTW, at risk of a tangent (your comment about non-neuron cells playing roles), it's been really interesting to me seeing how a key difference between artificial and biological learning has been clearing up. In biological neural networks, weight cannot flip sign (Dale's Principle). In the general case, a neuron is either excitatory or inhibitory (usually a small number of inhibitory neurons per cluster of excitatory neurons); it can't change from one to the other even if learning would favour that. At a first glance, that would seem to cripple learning capability (and definitely does if you implement that in ANNs). But what appears to actually happen in biological neural networks is a sort of horizontal learning, co-dependent synaptic plasticity, between excitatory and inhibitory neurons. Instead of merely weakening an excitatory connection down to zero and then being able to go no further, learning simultaneously weakens the excitatory connections and strengthens the inhibitory connections. The excitatory neurons are the primary drivers of information storage and processing, but the inhibitory neurons adjust the baseline to give them the flexibility to express negative net activations as needed.

It is a myth that individual bees only retain information for half an hour. Depending on the memory at hand, bee memories can last days, weeks, or even the remainder of their foraging life. They have to remember things, because the timeframes a hive operates on are much longer than half an hour, including night time and being kept inside by inclement weather for days or even weeks at at time. Individual bees also learn much more than can be conveyed through waggle dances, such as what colours and shapes of flowers are yielding best in a given area at what time of day (bee learning is essential to them being able to function as generalists, able to handle any mix of plants at any latitude).

Also, the hive doesn't just blindly accept whatever any bee says. Each bee functions as an individual in a society. When a bee waggles in the "town square" (on the comb), other bees gather around to "listen" (detecting oscillating shifts in the electric field plus tactile contact and sound). But whether a bee actually decides to make use of that information depends on whether they're having good or bad foraging success. Only a small fraction of bees on average (usually a single-digit percentage of watchers) will decide to make use of the information. And if another bee "disagrees" with a waggle dance - for example, if they've been there and found nothing, or worse, found dead bees, predators or a rival hive), they can make a counter-buzz to argue against it. The arguments can get quite "heated", with many bees taking part.

We think of bees as mindless drones (literally, we took the very word!), but they're all individuals each acting on their own. There are simply various rallying factors that keep them together (for example, the scent of the queen, the desire to live in a warm hive, etc). The information communicated within a hive is limited; bees overwhelmingly rely on their own mind and memory, and perform their tasks as individuals.

Interesting. Now, make an ICE version. I live rural and charging stations are very few and far between. The nearest is 20 miles away, but several gas stations are available within 3-5 miles.

I don't think an ICE version would be legal. You can't really hit the emissions targets without electronic engine controls.

As for charging, your house is the charging station. You might have to run an outlet and plug in an EV charger. If you've got a welder you've almost certainly already got a NEMA 14-50 or similar that will work. And if you don't have a welder, you should fix that ASAP! Everyone who lives in the sticks should have a welder and know how to use it.

Yes, but that is the end state of capitalism. Capitalism rewards business that can build competitive advantage, which includes barriers to entry for competitors. You may start out with a "free market" but most of the participants in that free market are trying as hard as they can to slant it towards themselves - to make it less free- and those that don't tend to lose out to those that do.

They try, and often they succeed for a while, but they eventually get disrupted by market changes. The most important thing is to be vigilant for regulatory capture. It's when businesses can enlist the power of the state in maintaining their moats that they can stay on top indefinitely.
