Communism/socialism requires some mechanism to compel cooperation with the collective’s objectives. The greater the degree of central planning, the greater the authoritarianism required to implement it. When you reach a level of centralization sufficient to justify the “communism” label, you’re well into the “authoritarian” quadrants.

- Comment on Clock logic 5 days ago:
Geometry.
The first clocks were sundials, which worked by putting a line on the ground. As soon as you comparing two different lines on the ground, you are doing geometry to represent time.
When you start messing around with geometry, you need an easy way to describe the angle of an equilateral triangle. 1/6th of a circle, or 1/3rd of a line. Trying to represent 1/3 or 1/6th in base 10 is fugly. Trying to divide a circle into 10 equal sections is just as fugly.
Dividing a circle into 6 equal sections is trivial: after you draw the circle with your compass, walk the compass around the perimeter. You have just inscribed a hexagon.
You’re still missing the angle of 1/4 of a circle: the angles of a square. Those are pretty important in geometry as well. It’s fairly trivial to draw another 6 points between the first 6 on your circle.
We use a 12-hour clock because of basic geometry. The 360-degree circle is the bastard child of basic geometry and a base-10 number system.

- Comment on Time to bash Americans again 1 week ago:
That makes sense from an outside perspective, sure. But your criticism was about Americans turning a blind eye to the “cultural” problem.
Within the US, blaming gun violence on “culture” means pointing out that 13-17% of the population commits (and are the victims of) 55-65% of the murders. Blaming “culture” means pointing out that mass shooters are predominantly white, they also account for less than 1% of all murders.
The Americans broadly adopting your “cultural problem” argument are MAGAts. Normal Americans are turning a blind eye to that viewpoint, rather than being lumped in with those racist pricks.
- Comment on Time to bash Americans again 1 week ago:
We “tend to turn a blind eye to it” because “cultural problem” is primarily used as a racist dog whistle.
If your intention was to point at the underlying cause, you need to be talking about systematic impoverization, lack of generational wealth, devaluation of labor, etc.

The alternative is some variety of private mortgage insurance. The insurer bets that housing prices will rise, so that you won’t default. If you do default, they reimburse the lender on their losses associated with your default.

Since shower water is a mixture of hot and cold, tank size, tank temperature, and cold water temperature are the predominant factors, at least initially.
For a given shower temperature, hot water consumption rate will increase at an exponential rate until tank temperature falls to shower temperature, then shower temperature will fall.

Laws are for generalities. Courts are for specificities. The situation you describe is resolved in the courts, not by legislation.
If the guardian is the problem, the courts assign a new guardian. That guardian can be another relative, or it could be a department of the state.
- Comment on The average age of Disney princesses is 505y. 3 weeks ago:
The same laws that protect drunk, unconscious, disabled, senile, or otherwise incapacitated people would still apply. Here, the 18-year-old with a child’s mind would be deemed incompetent, and assigned a guardian.

- Comment on AI experts return from China stunned: The U.S. grid is so weak, the race may already be over 4 weeks ago:
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.

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.

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.
- Comment on What would be ancient ways to properly store vitamin C? 4 weeks 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? 4 weeks ago:
Jams are preserved by canning, which introduces heat, which destroys vitamin C.

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.

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.
