Ford made the Ford Ranger EV 1998 to 2002, then the Ford Focus Electric from 2011 to 2018 before switching to the Mach-E. They are not "new at it". They're just bad at it.

To be fair, I have a lot more hope for Ford than GM, as Farley seems to actually understand the critical importance of turning things around and the limited timeframes to do so, unlike GM, which still seems to only care about press.

Also, employment is a lot less stable than it used to be. When I entered the workforce in the early 80s it was still common for people who were retiring to have worked for the same company all their lives. Young people now live in a gig economy; if they *do* work for a company, often they don't know how many hours they'll get from week to week.

And while things like TVs are cheaper than ever, essentials are often far more expensive. Median rents for a studio apartment in the US were about $250 when I got out of school; today they're $1200. If you have income twice the poverty rate and you follow the advice we were given back then to spend no more than 20% of your income on housing, you'd be looking to pay $483/month in rent. In most of the US even if you have roommates you'll be spending over $1000 per month.

Today it's more economically important to have a degree than ever. While wages for new college graduates have increased only modestly, wages for non-college graduates have dropped since the 1980s. Let's say you're thrifty and decide to commute to a state college. Your four year costs have risen from $3,200 to over $44,000. So families in their prime reproductive years are burdened with debt; it takes years to overcome that and to raise.

We often take poor families to task for being irresponsible and having children they can't afford, but the fertility rate in families below the poverty line isn't that high and it's remained steady for decades. What's happened is that the fertility rate at 200% of the poverty line has crashed.

Most women, with access to contraception and abortion, are doing what we told them is the responsible responsible thing. But if they *all* did it, it would be a demographic catastrophe.

Copper is not "the last mile". It's the last five meters. If that. When people talk about "the grid", they're not talking about the wiring in your walls. Which you don't have to redo anyway for adding an EV. Nobody has to touch, say, your kitchen wiring to add an EV charger.

"The grid" is the wiring leading up to your house. Those conductors are alumium, not copper. Occasionally the SER/SEU cable will occasionally be copper, but even that's generally alumium these days. And that's only to the service connection point (not even to the transformer - to the point of handoff between grid-owned and the homeowner-owned, generally right next to the house), e.g. after the service drop line with overhead service that descends down to the building. The "last mile" is absolutely not copper. Approximately zero percent of modern grid-owned wiring is copper, and even the short customer-owned connection from the drop line into the house is usually alumium.

Grids are not copper. Period. This isn't the year 1890 here.

And no, grid operators don't make money selling power. They make money providing the grid through which power is sold.

I have never seen a single utility that charges a flat grid access fee to residential consumers, anywhere on Earth.

Distinction can be hard to grasp for someone utterly ignorant on the subject

The grid is not made of copper. You thought it was? Copper is for home wiring, if that. Up to that point, it's alumium, bundled with steel on major lines for tensile strength. Does it look like copper to you?

As for the article: grid operators don't build out grids on a lark. They do it to sell power, because they make money selling power. If people want to buy more power because they want to charge an EV, then that's more money available for them. EVs are a boon to grid operators. They're almost an ideal load. Most charging done at night, steady loads, readily shiftable and curtailable with incentives, etc. Daytime / fast charging isn't, but that's a minority. And except in areas with a lot of hydro, most regions already have the ample nighttime generation capacity; it's just sitting idle, power potential unsold. In short, EVs can greatly improve their profitability. Which translates to any combiation of three things:

1) More profits
2) A better, more reliable grid
3) Lower rates

    * ... depending on the regulations and how competitive of an environment it is.

As for the above article: the study isn't wrong, it's just - beyond the above (huge) problem - it is based on stupid assumptions. Including that there's zero incentives made for people to load shift when their vehicles charge, zero battery buffering to shift loads, and zero change in the distribution of generation resources over the proposed timeframe. All three of these are dumb assumptions.

Also, presenting raw numbers always leads to misleading answers. Let me rephrase their numbers: the cost is $7 to $26 per person per year. The cost of 1 to 5 gallons of gas per year at California prices..

Once upon a time, the railway station in Las Vegas was downtown.

Or to put it better, Las Vegas grew *from* the station.

The old classic shots you see of Fremont street were taken from entrance of the Union Plaza--the hotel eventually built on the railway property.

You actually accessed the station *through* the casino.

I took Amtrak from it to Iowa once. The oddities of accessing central Iowa by air at the time meant an overnight stay/airport sleep! So taking the train meant leaving at about the same time as for the airport.

I'm sure it makes sense to *someone* to not simply join up with the existing track and stop there again, but . . .

Comment waste of money and not our first high-speed rail (Score 1) 236

We have others that are considered high-speed rail, so this is NOT America's first.
But, like many others of Biden's wasted $, this is another project that should not be approved and hopefully, Trump (or next president since it will not be biden) will pull the $ from this. Why? Because this is by far the single best route to put in the world's first hyperloop. It is not just ppl that move from LA to LV. There is a ton of cargo that gets sent. Hyperloop needs to be done with cargo FIRST, and ran for 2-4 years before accepting it for manned travel. And having Cargo travel at 300-500 MPH between these, at costs cheaper than trucks, would be a big deal.

Speaking as a local the monorail was insanity from the start.

At the time, the taxi companies still had the "juice" (as it's termed here) to block it from going to the airport, which would have been part of any sane plan.

AFAIK, its only sane feature was meeting the requirement that the cost of demolition be escrowed.

In its bankruptcy a decade or so ago, Judge Markell actually rejected the agreed reorganization--something quite rare. He pointed out that, in spite of the agreement,
a) the court had an independent duty to review, and
b) one of the requirements for confirming a plan being that it wasn't likely to need another bankruptcy--and that this one pretty much locked in another one down the road.

Extending it *might* make sense; I don't know the current economics. But if so, it should go to the airport, downtown, and the nearby stadiums--or don't bother.

And if we're going ahead with tunnels (a big question itself), the monorail would be redundant, anyway.

Comment Re:Starship (Score 1) 27

For SX to set up a base on the moon and mars, they will need 2 different types of landers: Cargo and Manned.
With manned, it is easy enough for ppl and supplies to be transferred from space-only to the lander. The question becomes, what about the cargo version?
So far, SX has shown a door on the side, but I believe that there is NO WAY that is going to work. The reason is that the cargo will be pulled out and then have to be stacked directly below the door. In addition, assuming that lunar and martian cargo systems never return to earth surface, then we need a way to move cargo from the starship leaving earth to the lander, or possibly something in-between.
With that in mind, about the only system that I can imagine would be to use the nose opening, docking nose to nose, and then having containers, moved from 1 system to the other. Finally, when landed, the nose is opened up again, and a crane on the inside is used to pull the container out and place it on the side. What is interesting is that the crane could be attached to the rocket via a track that runs on the inside so that it can rotate around the lander and drop off containers directly to the ground as opposed to being forced to stack them.

Now, as to starship:
1) trivial for it to reach orbit. It was not because they are not working on orbiting, but on all of the stuff in-between such as take-off, separation, fuel pump testing, re-entry and landing on a single spot.
2) It is highly likely that SX will launch a couple of starlinks sats on this next launch. If not, it will almost certainly be the one after that. IOW, they will start using it for Cargo. 3) Re-fueling in orbit is not a big deal. They tested this in the last launch, internally. In addition, liquid transfers have been done for a long time (water, lox, fuel for ISS and other modules). They will need to build a tanker and a fuel-depot, but tanker will likely happen this year.
4) manned rating for launches will take a number of launches. Of course, that is exactly what SX intends to do with starlink cargos. Even if landings are not working yet, they will continue to use this to put up their starlinks that can not go on F9 ( though possible on FH ). The interesting item is how to test the life support. I suspect that they will be putting up 1 or more of these as space station module. Each 1 has more volume than the entire ISS (and far more than China's space station). Just by putting up the first one as a regular starship, they can sort things out for the ECLSS as well as layout, etc. Ideally, they would build several of these with later ones have multiple docking ports. That would enable these to quickly replace the ISS, while others continue to add their units to these for testing of their modules/ECLSS.

And yes, of this could be done before 2026.
Of course, that leaves the lunar lander. I would have to guess that once SX is able to land booster and starship on earth, they will have no issues landing on either the moon/mars. The only real issue will be (re-)entry into mars. The atmosphere is thin, but it is still there.

Funny that to you, "Israel" and "Jews" are synonymous. As if all Jewish people unconditionally support all actions of the state of Israel, even those which are highly controversial within Israel itself.
