The GGP is clearly talking about trains, not electrified roads, and next one was trying to snarkily ask if we need to build a train to every door in an attempt to claim they don't work. I (who is not European btw) tried to point out how stupid this was because you can use another form of transportation to reach the rail head, without the strange idea that you must use that form of transportation for the entire trip. I suppose I should have mentioned airports to try to get the idea through your thick skulls.

Though electrified roads using induction recharging are obviously stupid, even they would not need to be built all the way to everybody's door. The car is capable of travelling some distance off of them, so just like train stations and airports the grid can be way smaller than everybody's house.

OP Flyswatter wrote: "That comes in the form of a cord and is more efficient." referring to losses of power between direct and inductive charging.

NP Valgrus Thunderaxe replied:"I think the idea is ultimately to put the charging into roads." self evident meaning.

NP Saloomy replied: "Also a stupid idea. It's inefficient no matter what. The right solution is a conductor that pops out (or up) automatically from the ground or from the parking spot. I have felt that a robust connector should either shoot up from the road, or to make it more maintenance free, down from the vehicle. Using magnets for inductive charging is inherently inefficient, when compared to beefy copper conductors and nothing will change that. We are too lazy to manually connect and disconnect it, so just make it automat"

NP Drinkypoo replied: "The right solution is vehicles on rails, which solve the steering, tire dust, and tire inefficiency problems. All of the attempts to make cars make sense in this age are wasted effort. Cars make sense for some situations, but not the one we're in now where we have way too many of them for our own good.

I replied "Do you have calculations to make every road in the US function this way, or do we all have to move to cities and embrace the urban gestalt?

Then you replied: "There is a wonderful invention called a "parking lot" which removes the needs to build rails to your door. You might want to check into it. Europeans seem to have figured them out." Seemingly you believe that there are no parking lots in the USA.

And for myself, I posted that you have deep seated insecurities. You show it by posting a blatant Eurocentric uber alles non sequitur, then try to use only Drinkypoo's comment about rails, and ignoring the charging topic of the other posts

You might consider letting the adults have their conversation, or if you wish to post more of your insecure drivel, we can at least laugh at you.

Or even... maybe... pay attention, and join the conversation as an adult, without the weird non-sequitur digs. At this point, it is pretty clear that you pick and choose

Bring a hat and water.

Seriously, though, if you do focus on the cities first, that's 90% of the solution anyway, You have to start somewhere and you may as well start with where the most number of people are benefited.

Keeping with the conversation flow, we were talking about highway charging vs parking lot charging in the mix.

At least here in Pennsylvania where I live, there is no issue with electric chargers in parking lots. We have them in parking lots, convenience stores, and even in some fairly remote areas, like some state parks. In an ironic twist, sometimes many miles before an ICE driver can fill up. The IC driver might run out of gas while the EV driver pulls out with a full charge.

So the parking lot paradigm doesn't have to be an urban vs rural fight. When the concept some people espouse, like charging while driving is used - the other half of the conversation, you have to be willing to invest in a huge amount of disruptive installed infrastructure, when building out a parking lot requires a huge amount less disruption. Locally, pretty much no disruption at all.

We already have them my insecure European friend.

Seriously, the idea that Europe in its incredible superiority, has parking lots with chargers, while we subhuman's in the hinterlands don't would be funny if it wasn't top level copium.

And while you search for any reason to sling some shit on us, if you had actually paid attention to the conversation, we were talking about electrification of roads in the mix. Of course electrification of parking lots is the best move, and that is why we have them. We even have charging ports in our more remote site parks.

Funny how you act superior, when your reading comprehension shows elsewise.

Do better, stop the insecure cope. It is not a good look.

You perfectly illustrate the urban uber alles outlook.

No, I've been a bit lazy about that, if I'm honest. And I usually am. But you'd start from city centers and push out to where you can put cheap parking, which you'd combine with solar farms of course. I don't envision eliminating cars from everywhere ever and I also don't expect it would make sense to do all at once. I guess I'll have to go looking for papers on this soon. It's so tedious when you don't have institutional access...

I sense a zinger there, Drinkypoo! 8^)

You note a parking area - Yup, something similar to the Terminal area in NYC. People coming into the city in private autos park thier cars in the big terminal parking lot, get onto public transport, and it keeps a lot of cars out of the city. A pretty good solution. To my mind, there is where charging stations should be. Park your car there in the morning, go to work, and come back to a charged vehicle.

That is certainly a lot less expense and infrastructure buildout than trying to electrify all the roadways.

That's what various larger cities have been doing here in NL: building Park&Ride hubs on the periphery. People drive to the city and transfer to public transport there. Judging from how full those parking lots are, it's a popular option.

Oh yeah. We have a terminal right outside New York City that is the same thing. Likewise the lot is quite full. Trains between NYC and Philly running all the time, packed with people. Add in Boston, and it's people, people, people.

In such concentrations of humanity, you simply have to have some manner of public transportation. No choice. It's all about how much space has to be provided for private autos.

But give it a thought. We do our level best to keep personal autos out of the very place some think we should start building out charging electrification.

Now I'm not the sharpest pencil in the box, but if I'm developing a place for people to charge their cars, I'd look at this parking lots and think - "There's a place for charging." It has so many advantages. A substation will probably be needed. Park your EV in the morning, and come back to a fully charged EV at the end of the workday. No car in the city, adding to parking and traffic woes. No miles of infrastructure needed for the wireless concepts and their IR losses.

Back of envelope calculations here with a number of assumptions:

Outside of the densely packed urban areas, roadway charging really doesn't work. If we take my state of Pennsylvania for instance, we have around 251,700 miles of paved roads. 2,575 miles in the Philadelphia area, and Pittsburgh has about the same. Note, there are other cities that are much smaller. So with around 5 thousand miles in Philly and the 'Burgh, and let's assume another 10 thousand miles in the rest of the urban areas, we can end up with around 230,000 miles of non- urban roadways.

How are we going to accommodate that? I'll note that for the traveling challenges here in PA, a lot of people prefer to live in the uncluttered areas, because it is so darned beautiful here. I might have to drive 50 miles to get to another town that is only ten miles away - if in a straight line - but the drive is always a joy.

So roadway charging will be a pretty hard sell.

I agree with that too. I could go with small, amusement ride types of rail just running up and down the street that just has seats, and shade. My commute may be walking some, hopping a ride on a 15mph mini-train, more walking, hop a train. I think that would be fun and stress free.

When I see these sort of posts, I always think the poster has an urban only outlook. What is your solution for the rest of the country?

While Cassandra was usually correct, she was rarely appreciated

These days she would be unable to raise an IPO, but then what is the profit in collecting space trash, until AFTER something horrible happens

What you describe is exactly what happened a decade or so ago near where I live. A local road had a long straight stretch along a hill. At the top was a curve. The curve banked the wrong way, and dropped in the manner that made you weightless for a short time.

We locals said You have to fix that! Pretty simple. Grade off the hump, and repave that 100 foot section with a proper bank. There were Township meetings where the concerned people were told just to drive better, they were just being overly worried, and there was no problem.

Then a college student driving up the hill on his motorcycle ended up launching himself into the front end of an oncoming truck. A 4.0 Average kid from a well to do family. He had a bright and productive future ahead of him. Died at the scene.

The next day, the equipment came out, graded off the hump, and repaved about 100 feet with a proper bank. The overly worried people were wrong until they were right.

The same thing is going to happen with the upcoming Kessler event. Except that correcting the problem will take a very long time. And most of that will be waiting for the debris to fall out of orbit. And we can't forget the randomness of the debris field. that trading of energy between colliding objects will launch debris in a multitude of velocities and new orbital shells.

They are making big moves in space, yet they are currently the biggest source of new space junk. Does this make any sense? If they keep leaving rocket stages floating around in the same area they need for their mega-constellation and other space efforts, they are shooting themselves in the foot...

If you are curious about their outlook and addressing problems, study the Soviet Union's work with radiation emitting elements. Failed reactors (no it isn't just Chernobyl, radiation sources left abandoned, prompt critical events. They shit all over themselves, so doing the same in space is just standard operating procedure.

I think for space travel we should put all our eggs in one basket. Just pick one provider and stop funding all competitors. That way if anything happens to that one provider such as a failure of buiness practices, leadership passing away, failure to inovoate, etc we can really feel the pain of it.

In fact we should do this for everything. Why fund 5 companies to work on a cancer drug, just fund the one who is already closest. Just grow corn. It is the only crop we need and we should find a single strain of corn that grows best. Monocultures are the best cultures.

No, we're not making Elmo the king of space.

If the Kessler Syndrome occurs the fundamental cause is the existence of "fragment mines" -- massive bodies that will persist in orbit a long time and continually shed new fragments as they are bombarded. That is what this article is talking about.

Just sitting here smiling, I've consulted for years that humanity are simply going to cause a Kessler event.The good news is everyone tells me I'm overly cautious. Too worried about things that won't happen. That everything will deorbit very quickly. Meanwhile, LEO especially gets more and more stuff in orbit. Nothing to see here, right?

I am apparently wrong - until I'm not.

Totally my experience with AI generated code. AI can produce good code up to a point but then, when it is not quite right, it doesn't grok its own code so cannot fix it. If you are an experienced engineer, you then have to work out what it wrote and then how to fix it, and there go your productivity gains. If you are not an experienced engineer, you're fucked. Start again.

I concur totally. I'm not a software engineer, and at my very tiptop best, a below average coder. But my experience with AI so far tells me that while "vibe coding" might help me a little, if I have something that needs a software engineer, I'll go to a software engineer at the start, not after I create a stinking pile of merde for the engineer to fix.

"Vibe" anything is the opposite of precise and competent.
