Despite industry efforts to promote clean coal, answers to the problems of coal ash are lacking

Ah, no. You ever worked in a coal fired plant Larry?

You ever drink out of that contaminated water table, Bubba?

Here in Wyoming, no. Your grasping at straws made up of what you read. Again, have you worked in a power plant?

I often find satan in the details (mostly I'm referring to my OCD....), and did today.

I pulled into a parking lot behind a Model X. I'd never noticed before, that they use the same single LED strip for brake and signal function.

Turns yellow when signalling, so you only have the other "brake" light showing red. (Not counting hi-mount).

Can't say I've seen rear lighting set up like that on anything else, but chances are there's other EVs @ same configuration......

I've never noticed this on taillights, but I've seen where a front headlight will turn off when the corresponding turn signal is active. This was during the daytime, so the driver didn't need the headlight to see where he's going. I assumed it was to provide more contrast for the turn signal and make it more visible.

Are you sure that what you saw wasn't two LEDs place closely together? It seems like it would be more complicated to make one light change color than to put in a second light strip.

Well, eyesight may not be quite as sharp as younger daze , but it's still pretty good.

Bi-colour LEDs have been around quite some time. Now It's got to the point where a young lad working in the last shop I was at put some programmable LED headlights into his ride..... you could actually program in colours that would likely get you into a lot of trouble (not his intent, just had the output and other features he wanted).

Adding parts adds cost. So that's one reason to keep the parts count down. Esp. in an EV, you want to keep all electrical loads to a minimum - another reason for just one strip of LEDs.

My first reaction - DOT legal ? When I thought of 60's/70's American cars - Turn signal and brake were often the same element, but were red lensed. Euro and Japanese cars started with rear separate turn signals, often dedicated amber units.

Somebody with an X in their driveway may post a vid proving me wrong, but I'm pretty sure it was just one single thin LED strip changed to yellow when signalling.....

Over the next few weeks, I'll likely notice abc other model examples (insert cognitive trigger term I don't know here...) for that rear LED singularity I think I saw, but today was the first time I noticed it....

Front signalling standards got relaxed/modified some time back. IMO, manufacturers wanted the compact module benefit (production-line-wise) of not having a separate turnsig/parking light assembly to install. Haven't looked it up, but I hope there is an SAE standard for minimum life-cycle on what is doing the headlight switching - but today that type of switching is relatively low cost and should be reliable.

I know why they do it (wouldn't see front TS otherwise), but for non-urban driving, it's the one reason I would stop using turn signals at night..... in the middle of nowhere, less light doesn't do it for me, esp. when turning a corner. Progress ?

Light deactivation for a turn signal is only daytime running lights, not a headlight.

Those are oil cars in that photo.

LNG isn't currently allowed to be transported by rail in the U.S. except by very limited special permits, and, as far as I can tell, in Alaska since 2015, and, lucky you, by issue of a special permit in 2019 from eastern PA to New Jersey. As far as I can find, that special permit needed a study done first, which isn't expected to be finished until mid 2022. Also, they had to build a terminal in New Jersey to receive the LNG, to be loaded onto ships, to be sent to the Caribbean where it will be burned in power plants. Full testing of cars capable of withstanding impact hasn't been completed yet, either.

So I don't think LNG is moving much by rail in the U.S. as of yet.

They say “liquified petroleum gas” on them. Hundreds of them here on sidings.
Eastern PA and NJ are heavily populated with everything from ghettos to mansions for presidents, and I’d consider their contents MUCH more explosive and hazardous than coal nuggets

I'm pretty sure I've seen that at night, but I'll have to pay more attention.....

Given the # of people with modern cars (all digital dash) here that can't figure out how to turn on the full lighting system, well past dusk, maybe the oncoming ones I noticed were only running DRL.

If that is the case, then there is an example where front-facing lighting sytems circa 1970 outperform what we have now (re. signalling).

I've seen quite a few people driving at night with only the running lights on. That may account for seeing the blinker thing.
