The cars compared were as I described. There are no truly comparable electric vehicles available today. Somehow you think that’s a dig at Tesla? It’s a compliment, and a lament.

Not at all. I would love one. They have made missteps however.
Not a fan of Musk.
What should be clear is I’m not a fan of bullshit.

I’m also not a fan of monopolies.
I’m also not a fan of successful companies bargaining away their tax liabilities for little in return for the public.
I’m not really a fan of space tourism for billionaires either, not while poverty exists. What a waste of resources for no return.

Chip shortages are the only real obstacle, the rest are speed bumps.

It’s a problem if you don’t want to pay $60k for a $25k car…I thought inflation was bad. Now you love it?

Tesla made deals to not pay taxes. You can pretend that’s patriotic, it’s not. I didn’t say they ignored or committed fraud to escape taxes, I said they don’t pay them. That kind of agreement shouldn’t be acceptable for any company, especially one as profitable as Tesla. Yes, it’s a “the governor and/or legislature can waive taxes for companies he likes” policy issue, I find it abhorrent no matter which party does it, they both do.

If you backroom deal with right wing governors/legislatures to avoid taxes, you are far right, at least economically. I thought he came out as a Trump guy too, but might be wrong.

I've got a Technics TT that'll play 45's and 33's! It'll also slow or speed up to 8% let's get crazy with it!

Yeesh some of those rocks were bigger than her head - I can't imagine that helmet would have done much to protect her from a rock that size traveling with that much speed. So lucky.

The speed at which that thing ends of spinning looks terrifying(3:44). What can't that thing tear apart?

In my M1 (motorcycle endorsement) class, we learned this as "breaking the plane". There's a lot more force involved so you kinda have to consciously do it above a certain speed. Knock the front wheel in the "wrong" direction so that the bike falls into the turn in the direction you want.

In general I love the Ve channel, but I think this video does more to confuse people than to enlighten them.
Also, no mention of "holes" (even though that's more part of semiconductors).
Also, of the multiple-choice answers, there wasn't one corresponding to 80% speed of light which is the measured speed of electrical signal in copper (depends on the cable itself, frequency, and other factors).
And if all of the power actually travels through the air, then why does the ampacity of a cable matter at all? Tesla could be quick-charging with flimsy cat5 cable!

Maybe I can illustrate better.

The 'answer' they give is less clear than it could be for illustrating that purpose. That is to say, the very small electric current that is transferred 'wirelessly', would work exactly the same if your wire were never connected to each other period. Making it a loop as the example, then ignoring the transmission of force on the electrons along that connected wire is unduly complicating the example. If you want to illustrate that current in a wire generates a mag field, and that mag field in turn can induce a current in another wire is much better done by pointing out the result is the same if the wires are not connected.

It also avoids re-inforcing the very common misconception people have about electricity in wire not being subject the the speed of light...

Nah I dont see a bait and switch. I see people thinking electricity goes down wires while the underlying real world is fields propagating through space.

It really is a difference if you have the lightbulb 1 meter away or 1 light second away. We have a tendency to think abstractly of these situations, freely giving things ideal properties that they dont have and taking away the properties we dont like to use in our petty examples.

If you had enough voltage to overcome the drop in "ideal" 1 light second long cables they sure as hell would induce enough current in parallel cables 1 m away to light a bulb :-)

All that said people do under-appreciate how fast the speed of light is, just as they under appreciate how much a billion of anything, especially money, is.

The speed of light is getting to your destination instantly from your own point of view.

I’m thinking Mt Chimborazo in Ecuador…at over 20000 ft, it’s peak it the farthest from the center of the earth (while not being the highest above sea level thanks to the equatorial bulge).
Sure, it doesn’t remove air resistance or friction, but halving it, even cutting it by 1/3 is a massive leap in efficiency and negates much of the extreme engineering and materials needed to overcome the friction….plus, as you mentioned, there’s the rotational speed advantage from launching on the equator vs Florida.
Also, while extremely minor, there’s also a slight reduction in gravitational pull at those heights. A joule saved is a joule earned!

This is also a trick question, and in a way that I kinda dislike because it additionally confuses matters by the setup.

Specifically, any change to the electrical field in the wire triggered by something like flipping the switch IS always limited to propagating at the speed of light, and as such WILL take 1s to travel the ~300,000km through the wire.

There's a bait and switch here though, were if the wires are close enough, and the power on the wire is high enough, there is a strong enough magnetic field in the wire to reach across the 1m distance to the end of the wire by the light bulb. That magnetic field will induce a very small electric field on the wire as well. Calling that 'lighting' the bulb though is 100% a trick question though as no existing light bulbs are sensitive enough to light up from that little current unless the 'live' side of the wire is both in very close proximity and running very high voltage.

The part I dislike, is too many people believe that electricity running in a cable is 'faster' than light, and the trick here kinda re-inforces that rather than helping to clear that up for people.

Infrastructure improvement of bridges, highways, roads, ports, waterways, and airports—accounts for only $157 billion, or 7%, of the plan’s estimated cost. The definition of infrastructure can reasonably be expanded to include upgrading wastewater and drinking water systems, expanding high-speed broadband Internet service to 100% of the nation, modernizing the electric grid, and improving infrastructure resilience. That brings the total to $518 billion, or 24% of the plan’s total cost.

The rest mostly for buying votes via pork.

Looking up at speed, especially if there was a curve could derail the train. That train was at speed and even if the engineer locked it up it would have been the same result. Another reason why the brakes might not be engaged is that the engineer ducked down into a part of his cab that is a bit more safe... remember those guys take the brunt of these types of collisions sometimes. I really feel for the poor truck driver... he sounds like his livelihood just vanished and he is realizing it.
