Americans face a real chance of losing their health care if their job circumstances change. Those of us who live in civilized countries tend to forget the US is the only (putatively) non-Third World nation without universal health care.

Love it! Notice how quickly the far right trolls modded me down to zero. -1 incoming quickly, I expect.

I wonder whether citizen meteorologists might be able to pick up the slack created by all the DOGE layoffs and restore US weather forecasting to previous competency. Perhaps another incident like the deadly flash flood incident in Texas could be avoided.

Yup, one stated reason for the RAT on documents I have seen is to extend the data collection by the FDRs by maintaining power to the sensors and canbuses.

That's how I read it. It should say it has no thrust.

A typical jet turbofan airframe has two engines that each have a generator shaft taking turbine energy and making electrical current. It then has a whole 'nother turbine engine used on the ground and in some other flight legs called the APU; this exhausts out the tail cone usually, and can start engines or provide extra hydraulic power if needed, but is slow to start just like the main engines.

For power loss emergencies, a small spring-loaded fan pops into action super fast, called a Ram Air Turbine or RAT. It can only make enough electrical power to reboot key systems like engine FADECs or avionics, often only on one electrical channel instead of all channels. It's only a turbine, not a thrust-producing fan. It's a pinwheel toy in comparison to the APU and even the APU cannot produce significant thrust.

Yeah. Even here in Iceland, which isn't exactly a solar paradise, these would be really useful in some places. Though realistically your best option would be a mix of solar and wind.

I think we're forgetting the other two possibilities in this grid: "solar mine" and "strip farm".

The... trees?

If you're annoyed by jet skis, I would strongly recommend not living on the shores of Lake Havasu. Also, yes, it does take way more energy to get there than it does to jet ski around while you're there. Also, there are electric jet skis.

Do you drive long distances without stopping to get food and drinks?

If so: please stop that.

My language does reflect the new reality. By your own admission EVs are a minority.

Would you say that white people should be called "normal people" in front of a bunch of black people in the US, because the black people are a minority?

You talk about EVs like they're some obscure just-invented thing. They're not esoteric.

We're not talking weight, we're talking wind resistance.

You very much are talking both. For an extreme case, with freight trucks, aero is only like 1/3rd to 1/2 of aero losses. And they have aerodynamically awful shapes and are on very low rolling resistance tyres (though also have very heavy cargos... but also very large frontal areas).

For a passenger vehicle / truck towing a trailer, it will really depend a lot on the vehicle and trailer. It's not even some simple additive process, the aerodynamics is complex; it's actually possible to even lower Cd by towing a trailer in some cases (though not usually). And if by definition of the topic at hand (discussion was of a "big" trailer), then you're talking something like similar to the vehicle's mass (F-150 can tow up to 3 times its mass). Which - if on the same tyres - then doubling your mass equals doubling the rolling resistance. The ratio between rolling and aero resistance at highway speeds varies on speed, vehicle, tyres, weather, etc, but saying 60:40 aero:rolling is probably reasonable at normal "towing" speeds (somewhat lower than drivers without trailers) and averaging across weather conditions. Doubling the rolling drag increases the total drag by 40%. If your cross-section stays the same (again, this depends on the vehicle and the trailer), the Cd would need to rise by 67% to keep the ratio between rolling and aero the same. Which is a really big Cd rise. Now, if you're starting with a very aero vehicle and have a very unaero trailer, sure, you might pull that off and then some (but remember that it's not additive, the airflow is complex). Or if it's a low car and a high trailer, again, same story. But to treat rolling as negligible is just not right. Trailers add a lot of rolling drag, amounts that very much are relevant.

First off, "normal car", please. 20% of all new cars sold worldwide are EVs now. Update your language to reflect the new reality.

Secondly, that's just not true. Towing a heavy trailer with a truck will see its MPG drop by like half. The rule of thumb is that every 100 pounds you have a truck tow drops its fuel economy by about 2%. 2500lbs = 50%. That's a very rough rule, but it gives a sense of what's normal.

You won't be "hanging out" - your car will be ready to leave before you are. By the time you go in, use the restroom, buy a drink or a snack, and get back to your car, you'll have already added the range you need to go to the next site.

Unless you need to get really full because you're in a charging desert (charging slows near the upper end), it basically is this way already, if you have a fast-charging EV and a powerful charger. And speeds just keep rising.

You sure? Plugshare says Goffs has a 16kW NACS.

A Model 3, not towing anything (US ones don't come with a tow hitch, right?), arrive with 2%? I assume you're kidding. ABRP shows a 2024 Tesla Model 3 LR with 18" aero wheels leaving Barstow at 100% arrives at Needles at 55%. This is with seasonal weather enabled, and battery degradation of 5%. Switching to the SR, it arrives at 42%.

Let's see how bad conditions I have to choose to get it as low as you're saying. Let's try some random things.

SR: Going 10% over the speed limit. It's 50C (122F) - about 20F over the July average - and there's a 10 m/s wind (22 mph) - double the average - that the car is unlucky enough to be driving into head-on. That arrives with 1%

LR: Going 25% over the speed limit. It's 57C (135F) - as hot as the Death Valley record - and there's a 20 m/s wind (45 mph) - quadruple the average - that the car is again driving into head-on. That arrives with 4%.

Of course, if the SR just drops its speed to the speed limit it arrives with 10% remaining, and if the LR drops its speed to the speed limit, it arrives with a no-stress 27%. Even in these conditions. Both cars are, again, assumed to have 5% degradation.

So I'm not sure what you're talking about with your Model 3 claims. But I'll totally buy that towing something big and heavy will make that route non-viable. Towing dramatically increases vehicle energy consumption (not just EVs, either - all vehicles), like double the drain. Though I'm a bit surprised about jet skis being that much of an increase, as mentioned earlier.

I find that surprising - I wouldn't think a jet ski would reduce range that much (to 144mi). A big trailer like a caravan or large boat, sure, that'll double your energy consumption / halve your range, but jet skis are pretty small. What version of X do you have, what sort of range reduction do you see when towing a jet ski, and how does your speed impact it? I'm quite curious.

I would have suggested "use a 3rd party charger", but then I remembered you're in the US and 3rd party charging infrastructure sucks :P There's only a single 3rd party charger on that entire route and it's CCS1/ChaDeMo, not NACS. There's not even a slow charger, unless you count Goffs, which is a bit of a detour.
