Range extender was definitely a requirement when I got mine in ‘19. But that’s because I did not have reliable charging available in the area.

It also came in handy for a bad road trip (charging stations more than my range apart, so I couldn’t otherwise get there from here, but hold state of charge kept it up at 75% with frequent gas stops)

Very much depends on the rating. A residential panel is something like 65”x40”. A commercial sized panel is something like 80”x40”. The cell size is relatively constant, but the bigger panels are 6x12 cells instead of 6x10. Newer panels have more efficient cells, and so higher power.

Panel manufacturers can also do odder sizes as required. Example: q-cell does a 94x51” panel. This is 6x22 cells, but different sized cells as well.

Most panels are 6x, because that results in an open circuit voltage of just shy of 50V, which is convenient for code compliance.

It’s not claiming: you can’t have an automotive paint shop. It’s claiming you can’t start a new paint shop. Specifically, if you don’t have one for your car manufacturing line already, you can’t set one up. Wikipedia shows 13 pages for auto plants in CA. Most of them have the verb “was” in the opening sentence. There are two current plants: Tesla Fremont and Toyota California. Both of these plants are over 50 years old, and only one of them produces actual cars instead of parts.

I promise there is not an OBD2 port inside the headlights of cars.

There is CANBUS to the headlights, but that is not a OBD2 port. And more securely designed cars can put that in a less secure zone, so it can only send and receive commands for exterior things like lights, and not be able to have commands for keys injected, because that bus will not accept those commands.

More advanced EVSEs are capable of adjusting the power delivered based on the power available. It does require a sensor on the supply cables to determine how much power is being used, but it's technically capable without a service upgrade. Also, electric companies will frequently upgrade an old 50/100 amp service to 200 amp for low or no cost (because they figure you'll pay off the cost of doing so through more power usage). The panel side of the service upgrade will cost you, but then you'll be able use the toaster oven at the same time as the A/C.

Quick sort usually uses something like insertion sort when the number of items is low, because the constants are better at low n, even if O(n) isn’t as good.

The third row is just planned. They do not have any publicly available views of it, and the currently non-removable back glass of the prototypes inhibit actually installing and using them.

The vast majority of tractor trailers in Europe are cab over designs. There’s definitely less room between the bumper and the driver’s legs in those than in any standard pickup truck.

I don’t think slate has a four door option. It’s still two door, but with a rear seat that you can clamber into after pushing the front seat forward.

Do you have power at the lake house? Then you have charging infrastructure. Also, why are you towing the boat to and from the lake house?

And again, which new production pickup fits 6 people?

You think a crumple zone isn’t required by current FMVSS, which they are designing against? That is, in fact, what they referred to with “ structural technology”.

No pickup will do that. Even crew cab pickups normally max out at 5 people (4 passengers), because there is no bench seat up front anymore. Even a Ford Maverick is $30k or so, and that won’t tow a 5000lb boat. Max listed towing is 4klb.

for example, the US has stopped sharing weather data with canada.

Citation needed. Most weather data from NWS is required by treaty to be disseminated through WMO compliant methods. The Metsat data is transmitted unencrypted from the GOES sats. I don’t believe they even have the capability to encrypt it. It’s only DoD weather data that’s not being widely disseminated, AFAIK.

10 gallons of water is like 80 pounds of snow. Even with the relative density, 80 pounds of snow isn’t going to do much for avalanche.

Doubt: the APQ-181 radar on the B-2 is a Ku band radar, about 15 GHz. Tamara is about 1 GHz. This is entirely incompatible frequency ranges.

Also, the APQ-181 is a LPI radar, which means it’s specifically designed to avoid correlation of signals such that you can track by the signals emitted. There are presumably some downsides to working in LPI, but the upside is that the signal is designed to be indistinguishable from an increased noise floor.

Most of the aggressiveness of a toy rocket is the smaller length. Orbital class rockets are literally the size of skyscrapers.

If there was a zip code that was just virtual PO Boxes, it could use the existing change of address machinery to slap the actual delivery address on when addressed with a virtual box. Assuming they used an entire sectional center facility for it, you could have 100 zip codes, with 6 digits of unique delivery points, so 100 million virtual boxes.
