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.

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 6 days 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? 1 week 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? 1 week 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.

- Comment on The way two of the usb's are one way while the other is another way 3 weeks ago:
I kidt had a problem with my boss’s conouter yesterday where Windows decided it didn’t need to load the drivers for one of the two built in USB 3.0 controllers. On boot, only one of the two controllers would work, either the one for the front ports, or the one for the rear ports.
BIOS recognized a keyboard or mouse in any of the 2.0 or 3.0 ports at POST, but if Windows failed to load the 3.0 driver at boot time, it dropped the keyboard and mouse.
Workaround was to swap them to the 2.0 ports. Final solution was upgrading to Linux.

Suppose he willed his car to his living son, his house to his son, and the remainder of his estate to Bob.
He dies. Son is alive. In this case, son gets house and car. Bob gets everything else.
Suppose son dies first. In this case, the house transfers to the son’s estate, where it is then transferred to son’s heirs. The house was bequeathed to the “son”.
But the car does not transfer to the son’s estate. The car was bequeathed to the “living son”. The car transfers to Bob with the rest of Dad’s estate, not to the son’s heirs.

While it’s not guaranteed, chances are very good that it can be reversed. If you change your mind later, you can attempt to reverse it.
Nobody should be having kids before the age of 30 anyway.

- Comment on "Pilot had to dive aggressively to avoid midair collision over Burbank airport." 4 weeks ago:
Without pilot intervention, the closest they would have come would have been 4.85 nautical miles laterally, and at the same altitude.
With the pilot intervention, the closest they came was 4.85 nautical miles laterally, and 500 feet vertically.
- Comment on "Pilot had to dive aggressively to avoid midair collision over Burbank airport." 4 weeks ago:
Agreed. The point of a conservative warning is to give plenty of time and opportunity to react without bouncing your passengers off the ceiling.
Fault for the loss of separation seems to be on the controllers. Not all separation incidents are the same, though. This one seems to be rather minor. By my estimation, the encroachment was a maximum of 264 yards, and the duration of that encroachment (without pilot or controller intervention) would have been less than 10 seconds. Too tight, yes. It needs addressed so it doesn’t become a habitual violation that could lead to more severe encroachment by these controllers. But there was no real danger of bodily harm from this encroachment.
Fault for an overly aggressive maneuver is on the pilot. There was a risk of injury from that overly aggressive response. The pilot’s actions elevated a minor, no-risk event to one that risked serious injury to the passengers and crew. But, he was following instructions from a device designed to improve aviation safety, and the nature of the warnings from that device, an over-response is much safer than an under-response. He has to trust his instruments, and his instruments (erroneously) told him to push the nose down, quickly, lest he hit another plane.
TCAS is designed and intended to reduce risk and prevent harm. In this specific incident, though, it seems like the TCAS-RA actually increased the risk of harm, by calling for an immediate action that wasn’t actually necessary to prevent harm. Is there a way to improve TCAS?
I, too, would like to know how often TCAS incidents were recorded before and after the layoffs. Those layoffs definitely harmed aviation safety. But if someone were injured in this incident, I don’t think I could point the finger at the controllers or lack thereof. This particular incident seems to suggest a shortcoming in the TCAS system.
