Reply to comment by CainIsmene in As they still have a neutral charge, can antineutrons replace neutrons in a regular atom? by Oheligud
Seems unlikely that the muon neutrinos will interact, but yeah.
And then the "antimuon neutrino" isn't actually a real eigenstate, so over time it will oscillate to other anti-neutrinos...

I was wondering how you got the data, and that open-meteo thing is extremely interesting for getting historical data.
Last time i looked at this, which is about 5 years ago, the solution proposed to me by friends in climate science was to download datasets for testing climate models, and extract (very rough resolution) it from there. Or you could buy observational data from a meteo service for way too much money.
Bookmarked!

That doesn't really matter tough. The force would be the sum of two terms that both goes like v^2, the plow drag and the body air resistance drag. So the total drag force still goes like v^2, and the power (force x velocity) like v^3.

Eh, a wall wart is cheaper smaller and less noisy.

You don't want to go too far overboard tough, switch mode power supplies aren't really stable without load.

Reply to comment by on_the_nightshift in Eli5 why aren't gas only vehicles far more fuel efficient than before by Live_Strongerrr
Also, there just isn't that much more you can do with an ICE engine - it's burning fuel to raise the temperature to generate overpressure which pushed pistons that turn "pedals", which then act through a complicated set of gears and linkages. Whatever you do, it's never going to be super efficient, most of the energy is lost to heating the coolant. And it's a technology that lots of people have already spent a lot of effort on optimizing, meaning most out the easy gains are long gone. Also, it needs to be fairly light and cheap to fit in a car, and work at a wide range of RPMs, torques, power levels, and it has to be reliable and not too complex.

The aerodynamic model, which is slightly smaller (still big) and flew like a plane, is in a museum in Germany.

Yeah, a huge lump of iron sitting inside a somewhat isolated bay won't go from pretty warm to -40 in a few minutes. That said, starting a really cold diesel isn't fun, and probably puts a ton of wear on it. Fuel freezing isn't really a problem tough, since there is a different fuel blend in the winter...

Also, starting a warm engine doesn't take much, compared to i.e. a normal or especially a really cold start. To start my old diesel car when its say -20c and it's had time to get really cold, takes a while, even after bumping the glow plugs a few times.

Oh, yeah. I have a picture of myself refilling a Trabant (old Soviet car), the tank was inside the engine bay, on top of the (hot) engine.

Reply to comment by CurnanBarbarian in ELI5: What’s car alignment? I read that cars should have it done regularly as part of their service. by LittleLostSadDeer
I had a crooked steering wheel for a while - there was a recall to replace some cable inside the wheel, and they put it back on slightly crooked. So it drove completely straight without needing any steering input, with a 5 degeee angle on the wheel. It was mostly unnoticeable on shorter drives requiring more manuvering, but very annoying on long highway drives.
It required an alignment to fix it.
