  I literally explained that the economic incentives necessary to maximize the potential of one were completely opposite the incentives necessary for the other.

  Again: nuclear needs daytime loads driven to off-peak hours. The difference between maximum demand and minimum demand needs to be lowered as much as possible, because nuclear can’t be quickly ramped up and down to match demand. That means increasing overnight demand: Lowering off-peak pricing for large industrial consumers.

  Solar needs minimum night time demand, and maximum daytime demand. It needs to drive consumers to daytime hours. Raising prices for overnight consumption, reducing them during the day.

  The two require opposite, incompatible pricing strategies to maximize their efficiency potential.

  Whichever one we choose as a primary, we drive the other to an inefficient auxiliary role.

  I literally just explained that.

  Exactly. That is exactly what we need to do.

  Then the rest of the year we have cheap hyper-abundant power.

  Ideally, yes. But, what is actually happening is that near the summer solstice, generation rates aren’t “cheap”. They are negative. We are putting so much power on the grid that generation companies are paying for people to take it off during ideal generation conditions.

  That is a big fucking problem. Negative rates mean we stop “spamming” solar panels long before we have enough to meet winter demand.

  The solution to that problem is 3-season industries. Major industrial consumers that only operate from spring through autumn, soaking up the excess power, then going offline, shedding their excessive load for the winter.

• ⁨Comment⁩ on ⁨AI experts return from China stunned: The U.S. grid is so weak, the race may already be over⁩ ⁨⁨5⁩ ⁨days⁩ ago⁩:

  Not feasible.

  It’s barely feasible to use pumped storage for solar to match the daily demand curve in some small areas. Grid scale storage cannot be feasibly scaled to serve our current overnight power needs. But the daily demand curve isn’t the problem.

  The real problem is the seasonal variation.

  For solar to be effective, it needs to be able to meet our winter demand with our winter sunlight. 9 hours of low-angle sunlight under largely overcast conditions. That means we need a lot of solar panels, to get sufficient power from these suboptimal conditions.

  Now, take that same number of solar panels, and give them the 15 hours of high-angle sunlight under largely clear skies that we have during the summer. When we do this, we have so much power pushed on to the grid that the price of electricity actually goes negative. They literally have to pay people to take it.

  There isn’t enough lithium in the world to make the batteries we would need to balance seasonal variation. There isn’t enough land on the planet to support pumped storage facilities that could balance seasonal variation.

  We need demand shaping to make solar feasible as our primary energy source, which means driving our heaviest loads to daytime, away from the dark. (This is the exact opposite of what we need to do for nuclear, coal, and other baseload generation.)

  We also need 3-season industries that can soak up excess production in spring, summer, and autumn, while going offline and shedding their loads during winter.

  Sure, sure. Now, about those Epstein/Trump files, discussing exactly how many children Trump has raped. When are those going to be released? Does the prison commissary currently stock his particular variety of orange tanning cream?

• ⁨Comment⁩ on ⁨What would be ancient ways to properly store vitamin C?⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  Fresh meat contains vitamin C, as most animals can synthesize it themselves. “Livestock” would have been the preservation method.

  Fermentation can develop vitamin C, depending on what you’re fermenting. Cabbage is probably the most famous example, but pretty much everything you ferment produces at least a little.

• ⁨Comment⁩ on ⁨What would be ancient ways to properly store vitamin C?⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  Jams are preserved by canning, which introduces heat, which destroys vitamin C.

• ⁨Comment⁩ on ⁨What would be ancient ways to properly store vitamin C?⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  Making jam involves heating the fruit, which destroys the ascorbic acid.

  Gilbert Blane was appointed to the staff of Admiral George Brydges Rodney as Physician to the Fleet in 1779. Blane was a medical reformer who was convinced by Lind’s original experiment with citrus and appreciated the need for a practical way of storing them. After considerable experimentation, he determined that adding 10 percent “spirits of wine” (i.e., distilled ethyl alcohol) to lemon juice would preserve it almost indefinitely, without destroying its beneficial properties.

  Bing is for porn.

• ⁨Comment⁩ on ⁨AI experts return from China stunned: The U.S. grid is so weak, the race may already be over⁩ ⁨⁨6⁩ ⁨days⁩ ago⁩:

  Nuclear and solar have competing problems. Nuclear is a baseload generator. It can’t ramp up or down fast enough to meet the daily demand curve; it needs a steady, stable load, 24/7. The steadier and stabler the load, the better. If the load drops off overnight, nuclear has to dial back its continuous output to match that trough. And again: It can’t ramp up and down fast enough to match demand, so it just has to stay at the lower “trough” level, with the remainder made up by various types of “peaker” plants.

  To make nuclear as efficient at possible, we need to drive consumption to that trough. We have to increase overnight demand as high as possible, to minimize our reliance on inefficient peaker plants.

  Now, look at solar. Solar stops generating overnight. Solar can’t possibly meet overnight demand without storage, and grid-scale storage solutions are fundamentally limited. To make solar as effective and efficient as possible, we have to move as much demand to daylight hours as possible, where it can be met directly by solar generation, without storage.

  The two technologies require opposing demand incentives. Making one more efficient necessarily makes the other less. Whichever choice we make here, the other one is relegated to a limited, auxiliary role in generation, and can never reach its full potential.

  I think showing them how to use PiHole or some other content filtering would be useful. Empower them to shape their own world.

  I mean, I was somewhat serious. Maybe not the “you don’t get to know your home address until you’re 10 years old” part.

• ⁨Comment⁩ on ⁨A Tech Rule That Will ‘Future-Proof’ Your Kids⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  I might be slightly facetious in my comment.

  If I were to be slightly more earnest, I would say that the authoritarian concepts they learn from enforcement of arbitrary restrictions like “no screens in the bedroom” are far more harmful to their well-being than the information they could put on those screens.

  The best “tech rule” I could give instill in them is an understanding of the concept of “click bait”. The sooner I can immunize them to paywalls and microtransactions, the better.

  Seems pretty effective.

• ⁨Comment⁩ on ⁨AI industry horrified to face largest copyright class action ever certified⁩ ⁨⁨1⁩ ⁨week⁩ ago⁩:

  I’m the troll?

  Everything here is about American copyright law, which is explicitly justified within our constitution, and has been horribly abused since Disney effectively set the definition of “temporary” to mean “forever, minus a day”.

  Yet you want to stick your special little foreign nose in here, and express your special little foreign opinion on how those copyright bandits deserve to permanently lock cultural iconography behind a fucking paywall.

  You don’t even seem to be realizing that you’re slurping on Corporate America’s asshole; that the special little opinions you are expressing are shared and promoted by our Head Cheetoh in Charge. In your zeal for shutting down AI slop, you are supporting the MPAA, RIAA, Disney, and Donald J. Trump.

  Pull your head out of your ass and critically evaluate the situation. Start with the fundamental purpose of copyright law, and who it is ultimately supposed to benefit. It’s not the content creators. It is not the publishers. It is not the various lobbying associations.

  The principal beneficiary of copyright law is supposed to be the general public.

  We are asked to temporarily give up our public domain rights and allow content creators a brief period of exclusive control. This is in order to convince content creators to continue creating, rather than building an entire industry devoted to resting on their laurels.

  The AI industry is using copyright law the same way that the general public was always supposed to be able to. You are siding with the abusers.
