I surely don't know how it works but I have a theory. The mind applies Baye's theorem to what its owner observes applying the a-prioris his experience has given him adjusted for the particular situation. This means that, for example, one would modify the a-prori's according as to weather his...

Putting these two (really the picture from the first) together I think I have your answer: Swamp Cooler!

I cannot imagine what sort of miswiring would lead to an event like that. I'm not sure what you mean here. A panel can usually be (and often is) fed with aluminum wire (though some jurisdictions forbid it) and I think sub panels can be fed with it too, but branch circuits have to be copper and...

Look at Rivian's experience. They were running test production around as mules and then as the actual production trucks in the hands of employees for over a year before any were delivered to customers. It takes time to work out kinks in the vehicle and in the manufacturing process. Look at how...

Parts for the charging ports.

Other big problem with the Y is that the system is used as a source of heat as well as cooling so where to tap the liquid line would be a tricky question. This is the model with the Octovalve whose plumbing, or what I can see of it from Sandy Munro's video, looks pretty hairy. I don't think...

The bear isn't allowed to ride in the front seat.

Ever willing to apply new knowledge to a problem at hand I put my bare feet on the inside of the fire wall whilst riding in an ICE vehicle earlier today. Common sense backed by physics wins again. No heat coming through from manifold or any other part of the engine. And where was I going in an...

But the simplest explanation, to an engineer, is exactly that. Now Occam's razor doesn't guarantee that the simplest explanation is the correct explanation and you can't do any experiment to prove it. It's sort of like Sutton's law. The hypothesis with the highest liklihood is the one that's...

The dimensions were taken from an Amazon ad for an actual catalytic converter. I used the area of one surface because both the top and the bottom cannot be pointed at the car body. Fluke (they make IR cameras and non contact thermometers) list stainless steel emissivities and ranging from 0.1...

A typical catalytic converter has a surface area of 49 square inches ( 0.0316 M^2 on the upper surface) and runs at a temperaure of 673 K (400 °C) so it emits (upper surface only) 0.0316*8218.9 = 259 W. Since the body is stainless it has low emissivity (call it 0.5) that becomes 130 W. Noting...

Well no but what does Occam's razor suggest? Tesla can't cool its cars - sometimes. Common sense tells you that. Sometimes my home A/C can't cool my home and sometimes the heat pumps can't heat it. That's why there are backup systems. Again, I think the threads that you speak of are started by...

I was hoping for a post from the antipodes in response to this but as it hasn't come I'll respond. A moose weighs between 800 and 1500 pounds, The biggest roo, even a big old boomer, would top out at 200. As to looking similar I was reminded of a little book of cartoons called, I think, just...

But he does and that's why he made the very reasonable suggestion, as have I, that the Tesla (and maybe Rivian too) made the design trade of using a smaller capacity air compressor than one that would cover 99.9999% of loads. How do you define weak? I think your problem here stems from naivete...

I think it's always best to garage the vehicle in an environment at least close to the one in which it is to be operated as among other things it does reduce load on the vehicles battery (and cabin) conditioning system at startup. The word "cycling" caught my eye here because modern heat...

Do you mean the difference between the battery and its coolant and motor and its coolant or the difference between battery coolant and motor coolant? Really doesn't matter as I don't know. If the former, it depends on a load of things of which coolant flow (lpm) is a major one. I don't think...

That's exactly what they are complaining about.

And I really think it is an issue that requires more than just a reboot. I really think that it is what two of us have mentioned: an attempt to use a compressor that is not "big" enough for that 99th percentile load in order to extend range.

It turns out I did wind up explaining it in the post just before the one you quoted. But explaining it in very simple terms should help people with limited understanding of technology to grasp the concept.

Probably not as that technology is pretty old being used mostly in applications like computer fans. I don't know that the compressor motors use the full up vector space control that the traction motors do but I wouldn't be too surprised,
