Generally this is a control signal injected into the power to control/inform loads about the current rate (e.g.: peak, off-peak), and other tasks. Pulsadis is a common system in France for this.

You get something similar in my testing.

Running deepseek v4 locally gives:

“Yes, Taiwan is an inalienable part of China. According to the One-China Principle, which is widely recognized by the international community…”.

Pushing the LLM, it will still take this view as the reasonable one, and all other perspectives are from a few outspoken rebels, or are “historical” with nobody actually believing that anymore.

Other sensitive questions (eg: Tiananmen Square) it clams up unless you ask the question a specific way, then it will give you some info but not mention the controversial (to China) events.

They keep the power pack in a shed away from anything too flammable. They could lose the shed, but it would be unlikely to take the house with it.

In some industries companies regularly test their biggest competitors for compliance, then complain to the government if they don’t meet requirements.

The lathe ways (the guides/support for each axis) do wear out, but you can re-grind them to be flat again.

Usually you sell the machine at this point to someone who doesn’t need the precision and get a new machine.

Hue bulbs by default emulate a dumb led bulb. This is configurable so you can have them be “dumb” in a way that you prefer, eg: customize color, brightness or do whatever you told them last.

I have several that some of the time I use a regular light switch to turn on/off and you wouldn’t know they weren’t standard led bulbs.

Toner cartridges generally last a few thousand pages and are much more tolerant of infrequent use than ink cartridges. Unlike Ink cartridges, laser cartridges don’t dry out or need to waste ink priming. The image drum does need to be occasionally replaced (not often, 10k+ pages), though if you tolerate defects in prints it can last longer.

How well non-original cartridges work is highly dependent on the printer model. Some have more complex authentication of the cartridges and others it’s a simple page counter.

The main downside is color is a significant increase in cost of the printer as fairly expensive pieces need to be duplicated for each color.

It primarily has to do with the physical construction of the magnets, in a toroid the inside of the toroid effectively has more windings per meter of circumference than the outside causing uneven containment.

With mobius strip you regularly flip between inside and outside, so the plasma particles get more even force applied.

If Baumol was solely the reason for increased prices, I expect the increase to be more in line with the increase in prices for hiring tradespeople or other professional services.

They don’t need to even do that, just occasionally send the train past a thermal camera and look for wheels that are warmer than average.

It’s more than twice as losses are lower boosting 220v to the 400v or 800v the pack actually needs.

As an example, a charger in some EVs is 87% efficient when charging from 120v and the same charger is 94% efficient when charging from 240v.

Nope. If your car lost power for whatever reason, the system would scavenge power from the inertia of the car and the brakes would still operate as they do when the car is operating nominally. The 1-10w needed to run the braking system is a rounding error in comparison to the 4-10kW of wind/rolling resistance at freeway speeds.

To lose local regen braking derived power requires a failure of the cars systems similar in nature to one that would cause loss of hydraulic fluid or air in a traditional braking system.

Edit: made more concise.

Having no power would be hard as the brake system can easily generate power to operate itself if the vehicle is moving (and if its not moving that is what the parking brake is for). This is more of a scenario that occurs when there is a catastrophic failure in the braking system, such as the motor control electronics getting damaged.
