Also, low-water-use plants tend to also be slow-growing. That's why they use so little water.

Hesperaloe produces 1.5 kg per cubic meter of water. This is comparable to the water use efficiency of forests used for paper, which is between 1.5 and 4 or so. So this actually requires as much water as trees, if not more. The only advantage, if you can call it that, is being able to plant it in places were trees won't grow.

But the problem is that this also means you'll be cultivating plants grown far apart, none of which produce very much mass per plant without taking so much that you kill the plant (whose roots are likely the only thing keeping the topsoil from eroding). That means you need an order of magnitude more land per unit of crop mass, and probably closer to two orders of magnitude. (Trees get tens of feet tall. Hesperaloe is a pile of long leaves that gets maybe a foot tall.) So the energy consumption involved in harvesting it is likely to also be one to two orders of magnitude greater because you might have to harvest an entire acre worth of red false yucca to get as much biomass as you'd get from cutting down one fully grown coniferous tree in a few minutes.

So you've gotten a little bit more crop land that nobody asked for, and/or saved a bunch of trees that were planted specifically to turn into paper, and in exchange, you've introduced a massively energy-intensive harvesting process followed by some other probably massively energy-intensive conversion process. This doesn't seem like a net improvement to me.

Either that or you harvest it including the root system, and yeah, you've gotten a lot of raw material, but now your topsoil erodes, and you can't plant anything there for a thousand years.

The process itself might be useful in some other context, of course, but it seems like a solution in search of a problem.

To be useful in deep space, you're going to have to deal with very harsh radiation, far harder than the Vikings dealt with. You really want to have some large number of computers, where the number has to be odd and exceed 5. The reason it has to exceed 5 is that you need 5 in order to be able to use the Byzantine General's Problem to discern which computers are working correctly and which are radiation damaged. Since some will be damaged over time and you want 5 computers still operating around the time the power runs out, you have to start with more than that.

Massively radiation-hardened highly-robust low-power chips could be done. If you were clever enough, you could do this as a wafer-scale system where you marked parts as bad and networked around them. Free space optical communication across the wafer might be doable.

They might well still end up being low-density CMOS discrete logic.

Lead-lining the electronics isn't as much of a problem if you've launchers capable of handling heavy objects and don't mind burning through a lot of ion drive propellant for course corrections. This would improve the hardening beyond what can be done through the usual operations.

But, yeah, you'd need defect-free microelectronics. You really can't handle F00F bugs or defective instructions once you pass Earth orbit. And I can't think of anyone who knows how to do that.

Well, not just the solar system but the heliopause as well, and the near-Sol galactic winds. We can estimate the effects of space from just about any ancient near-Earth space junk, but I'm not sure how we'd go about calculating the impact of the galactic winds on something. The Voyager sensors won't be sending back nearly enough high-quality data to establish that.

It's actually a lot harder. The fly-bys invovled gravitational slingshots, which not just steered the probes but vastly accelerated them. Without the slingshots, human rocketry of the time would not have had the capacity to get probes to solar system escape velocity.

Our understanding of asteroids is now reasonably good. We know they come in solid and rubble-pile formats. We know that several show signs of lava flows, suggesting they come from disintegrated planetoids with a liquid core. We've managed to land on some and even retrieve samples from one.

Our understanding of comets is much weaker. We know that several appear to be multiple bodies fused together with ice (the one we tried sending a lander to was of this type) and the break-up pattern for Shoemaker-Levy 9 is suggestive (but not proof) of it having been a composite structure too. The one icy body we've seen in the Kuipier belt was also two bodies frozen together. Photographs of the core of Halley's Comet also suggests two bodies fused together with ices. This leads to some interesting questions. Obviously the probability of this configuration is very high, but what is the probability of other configurations? Is it so incredibly low that the odds of finding single-body or triple-body configurations is practically non-existent?

(This is kinda important if NASA is serious about a DART-type project to redirect one.)

Our understanding of solar system captures is non-existent. If there are extra-solar objects flying through every few years, then there is a definite non-zero probability that there are significant extra-solar objects that have been captured by the solar system in the last 5.5 billion years. That would be kinda very useful to know.

Current solar system formation models don't work well, but planets have sorted their composition by mass. Studying them only tells us so much. Asteroids are more useful but hit each other too often, so we don't know how much mixing and reconstitutuing has occurred there. The Kuipier Belt is much better, from that point of view. The density is far too low and most of the objects far too small. A lander could obtain a lot of extremely useful data about how the solar system formed that we can't obtain closer.

The Oort cloud is theoretical only, at this point. The only way to find if it is real is to send something out there.

If we're to get any probes in the future to go between solar systems (and such missions are entirely possible), we need to know a great deal more about the heliopause and the galactic winds.

Probably LRO vs. Danuri

Well, viruses and bacteria. And that last one is critical.

We know that the microbiome alters blood chemistry and we know that this alters brain function.

I do NOT postulate bacteria cause mental illness, but I do postulate that there is a non-zero probability that bacteria can aggravate mental illness. And that is all that we need here. If we can develop a vaccine that triggers the immune system to either attack the bacteria directly OR to produce antitoxins which attack those changes in the chemistry which are harmful, then the vaccine would lessen the impact of this particular vector.

That would not prevent mental illness, but that's fine. Reducing it is perfectly acceptable.

We know that brain function is altered by the blood chemistry changes made by gut bacteria. This means that any mental illness exacerbated by this route where the chemistry added is verifiably unique to an undesirable bacterium can be targeted by the immune system.

Will this be all mental illnesses? Obviously not.

Do I know of any such chemistry? No, which is why I said "in principle". The potential for the vector exists and the potential for training the immune system to attack it exists, but the reality of such a vector actually existing is unknown and the safety of attacking it is also unknown.

"Potential" and "Unknown" are very important words here. They mean that we do NOT know if the probability of such a vaccine being possible exceeds zero, but equally we do know that a key underlying requirement has a probability that isn't zero. But that is all that we can definitely say at this point in time.

Although it would be wonderful if we could retrieve them, realisically we can't. And if we could get something to them to fit new nuclear batteries and replacements for components that cannot be revived, we could get newer probes out there with better sensors and a more powerful nuclear battery that could last a lot longer.

Having said that, I honestly wouldn't trust any of today's manufacturers to be capable of building anything with a comparable level of robustness, so a recharge mission isn't quite as stupid as it sounds. Almost, but not quite.

Still, fresh probes sent into the Kuipier Belt and the Heliopause would be extremely interesting.

So a murder suspect can appear in court and explain that someone gave him the wrong photograph, so it's not his fault?

The US, and many other countries, need to put forward a new law -- if an excuse applies to officials, then it applies to the citizenry. This is not because officials don't sometimes need extra freedoms, but because the vast majority of manmade disasters are "perfect storms" and because this case is a perfect illustration of the banality of evil.

Legitimate causes are just that and they won't cause problems. If, indeed, they are truly legitimate. Excuses mean that they knew they were doing wrong but felt that finger-pointing would confuse the issue for long enough for the storm to die down. Innocent people do not make excuses. Innocent people don't need them.

But this isn't something officialdom will ever accept. Nor will they tolerate a loss of power. So you don't take away their power, you merely insist that powers they claim are the same everywhere for everyone, and that the powers they deny are likewise denied to all. The sensible ones will see in seconds precisely where that's going to go and will get rid of the stupid ones very quickly. Not because they're morally better, but because such a rule is highly volatile and self-interest takes on a very different meaning when the consequences are unpredictable.

Except instead of pursuing policies that would help open models at the expense of Big AI, anti-AI people pursue just the opposite - policies that can cripple open source AI but have no realistic ability to meaningfully hurt big AI. It's so short sighted.

Actually, no, what they usually do is much more insidious: fingerprinting rather than watermarking. The fingerprint isn't actually included in the audio, it's included in a database. If they want to tell if the track was generated, they just try to match the fingerprint in the database. Can't filter it out of the track like you can with a watermark.

The two mainstream options (both about half a year old now, we're due for something better) are Ace Step-1.5 and Stable Audio 3 Medium.

Ace Step has full vocals with its music. See here for examples. The downside in my opinion (judge for yourself) is that it has Suno's flaw of sounding too "clean", "mainstream" and "uncreative", except even moreso (Udio was always much better than Suno at this, albeit "less well behaved" - but Udio is out of the game now).

Stable Audio 3 doesn't do vocals, though it has other useful features, like inpainting (great for fixing glitches in recorded tracks for example). In my view, it sounds a lot better. It can also be used to create sound effects. License is a bit more restrictive, though, if you actually care about that, but generally won't affect the average user.

Both are trained on fully licensed data and both are open-weights. So even if the devs released a version that included some sort of watermarking in the future (or someone developed a fingerprinting algo for the existing versions), you could just finetune them to break that.

TL/DR, if you want open source and want to just churn out a full track: choose Ace Step 1.5.
If you want open source and want to do instrumental tracks or to supplement manual work (such as your own vocals) or do audio editing: chose Stable Audio 3.

That's so little that it is completely lost in the statistical noise.

First, a natural gas turbine *also* requires hundreds to thousands of gallons of oil for lubrication every year. All turbines do. So with the exception of solar, no matter how you produce your power, you're going to use about that much oil.

An average onshore wind turbine produces 6 million kWh per year. (Offshore turbines produce more.) Petroleum-based generators use about 0.08 gallons per kWh. So if you used oil to actually produce the power, that generator would use 480,000 gallons of oil. By comparison, even if the fossil-fuel-based turbines somehow magically used a tenth as much oil, that would just mean the oil-based generator uses 479,730 extra gallons instead of 480,000.

In other words, the *tiny* amount of oil changes the greenness of wind farms relative to fossil fuels by about 0.06%, well within any reasonable margin of error.

It's noise.

A nuclear power plant uses 200,000 to 500,000 tons of concrete and produces a gigawatt of electricity. A utility-scale wind turbine might use 1,500 tons to produce 5 MW. So it's about the same amount of concrete per megawatt, to within a single-digit factor, depending on the duty cycle of the wind turbine.

And the foundation can usually be reused for the next turbine, so that concrete also lasts many, many decades, typically. They don't remove the entire structure when they replace the turbine.

Also, you didn't factor in all the extra concrete for building long-term offsite storage facilities for the nuclear fuel, or the concrete for the sarcophagus if things go sufficiently wrong. :-)

If blades are failing after a decade, then either A. something was wrong with them to begin with or B. the company that owns them stopped servicing them after a decade because of expiring tax credits. And that second one actually is plausible, but that's not a failure of the technology; it's a failure of U.S. energy policy. Why spend money repairing it when they can wait for it to completely fail and then replace it and then get the tax credit again?

I would argue that nuclear power stinks on ice. The cost per kWh is considerably higher than wind, and it requires continuous staffing and oversight to prevent things from going horribly wrong, whereas wind farms are almost entirely passive other than minor routine maintenance until something breaks and has to be replaced. Nuclear also requires transporting dangerous materials by truck or rail to storage sites, requires building storage that can safely contain the spent material for millennia, etc.

Also, every 40 to 80 years, the nuclear plant's equipment has to be replaced, and all of the removed material is contaminated, which means long-term storage of the reactor, pipes, concrete containment vessel, etc. You can't even recycle the raw materials like you can with wind, because nobody wants radioactive metal or concrete. And even if your blades are made of a material that can't be recycled easily, you can still landfill it instead of basically burying the entire plant in a no man's land for tens of thousands of years. If you think the waste from wind farms is bad, it pales in comparison with the cost and storage requirements for shutting down a nuclear plant.

If we get fusion working at an industrial scale, then we'll talk, but fission just isn't worth the hassle when there are other, much cleaner solutions.

> We need new laws to make life safer in the US and CATCHING Criminals.

Violent crime is at historical lows.

Most of our criminal laws are not enforced. If the police have extra time there is a whole Epstein Client List that needs arresting.

> tying the hands of LEO"S

Yes, that is the point of rights. Liberty is not safety. Europe is available for those who prefer safety over Liberty. Europeans who prefer Liberty should be welcome to come here. Cops who distain the rights of citizens should self-deport too.

Anyway, SCOTUS has extensively covered Mosaic Theory if you want the case law. Imagine being an LEO and ignoring the highest court in the land. That's just gang behavior.

> Government asserts that it will be able to identify all potential suspects

They went too far and failed.

They may be able to identify all suspects but even a clever six year old would ask, "and if they're not carrying an active phone"?

Geofence warrants were already struck down by SCOTUS and the government's position is arguing about the difference between beige, tan, and taupe.

Anyway it's a general warrant.
