All valid arguments about the EV with the current technology.
However it won't mean anything when you look back 20 years from now.
Similar things had been brought up about the combustible engines in the early days.
Ev's are the future and they're here to stay and take over.

I don't know? The massive cost associated with expanding the electrical grid to provide power for EVs may be a significant problem. I read where Californicate alone would need some $900 BILLION in upgrades. I guess we could get Elon to pay for it? LOL

Another couple of these clips that speak volumes. Chernihiv is cultural city of a quarter of a million people in Northern Ukraine. It has no military significance and is a long way from the current fighting. It is not even on any of the supply routs supporting the Ukrainian Army. This morning, on market day guaranteeing maximum civilian presence, the Russians struck the city center with an Iskander tactical missile with a thousand pound conventional warhead.

This is pure savagery designed solely to try and terrorize the civilian population. Yet we continue to refuse to provide Ukraine with ATACMS (uses the HIMARS launcher) because it might be seen as provocative by Putin.

Hard to fathom the callousness. I see that the US has finally allowed the F16’s to progress. Why so long? Can this be laid at Biden’s door or is it the pentagon?

This is the art of war as practiced by Biden's National Security Advisor Jake Sullivan.

He probably forgot all about the F16s? He was too busy banning gas appliances here. LOL

I feel like his presidency is like the movie memento. Every morning he wakes up, then someone tells him he's the president of the United States and he gets super excited and it's the best day ever.....

I hope this isn't behind a paywall. It is one of the most disturbing things I have read in years. It is not an individual opinion piece, but represents the opinion of the Washington Post itself.

It is essentially a lament that we are a constitutional republic rather than a true democracy where the majority rules absolutely. They clearly find the idea that each state has two senators a prescription for the evils and divisiveness that currently besiege the country. Minority power held by the unwashed 49% exercising that power unfairly through low population states, thwarts the progress the country needs to make toward more unified and obviously progressive future.

This design, hand in hand with the electoral collage, which insures minority and geographic representational rights, is a particular problem for the urban masses on each coast who should have majority power.

They further anguish over the difficulty of changing something so archaic as the constitution. It seems to be insufficiently agile for the growing needs of the burgeoning millennial majorities everywhere but flyover land.

The liberals on both coasts do not believe in checks and balances. Heck, they'd rather do away with the judiciary "encroaching" on whatever laws they'd rather pass.

A CA legislator famously said, "This is California; we don t pay too much attention to the Constitution". He said the quiet part loud as far as coastal liberals go.

There is only one advantage here in CA I see with the EV vehicles, and if I was commuting 50-60 miles to work each day I would buy a Tesla for that commute only. The one advantage is the use of commuter lanes with only one person in the car.

My only surprise on this whole thing is why they have not been doing something similar to this on a continuous basis from the start if they doctrine was to hit civilian populations for "shock and awe". Kinda modern day HIroshima tactic with conventional weapons.

They had plenty of time prior to the West mobilizing aid.

I am a patient person - my friends and family always comment on it. But I just don't see waiting that long to be able to drive again. Just a few minutes at the gas pump is what I expect and want. And, bluntly, it's going to be a long time (IMHO) before charging stations and their vehicles make it to places like rural Alaska.

I'd have no problem with the use case of the four hour interstate roadtrip using an EV. Provided that A.) It's a Tesla, not a piece of crap. B.) That I was going to stop for a bio/food break anyway so rapid charging is no big issue.

Where an EV loses its interstate practicality is if its a crappy brand that can't use the Tesla stations, and if you're on a trip of 9-14 hours on interstate. At that point, you may find a 20 min charge to be inconvenience since you're not likely to want to eat a meal three to four times on that trip while waiting for your charging to complete simultaneously.

I stay in Erie, PA several times a year and there is a Tesla charging area in the the hotel parking lot. Over the past 7 years I've chatted with the Tesla owners asking them about their experiences with interstate travel in their EVs. The opinions above were what I heard from their owners as well, ignoring the few fruitcakes that are on the far left and were doing 28 hour drives with 6-7 charge ups in a 24 hour period.

Donald Trump Abruptly Cancels His Presser Offering 'Irrefutable Evidence' of Election Fraud

redstate.com

Well gosh. Color me stunned. And the loyal trusting 35% never ever consider that they just may be the ones being played by this guy. Maybe announcing the now canceled presser brought in some more campaign contributions to pay his lawyers over the weekend?

Anyone who is still a Trump believer at this point thoroughly deserves to have their life ruled by Biden and Harris; but fortunately for them, there are still some of us folks working rationally to try and prevent that.

That particular teasing of a press conference is one of the most blatant dog whistles I have ever seen, even for the Great Orange Carnival Barker.

I don’t believe that when the combustion engines were invented the government told their citizens to give up their wagons, horses and drive a gas engine vehicle. I’m ok w the EVs, but don’t tell me that by 20xx I better be driving one. If I have to pay for something out my own pocket, I will drive whatever I want. If the Gov wants me to drive an EV, well they better park one for free on my drive way. Meanwhile I’ll continue to drive my Chevy 2500.

Sadly, your philosophy is just imagination, the government tells you what to drive right now. They do it in many ways, let me list a few: A.) Gas guzzler tax which makes large and high performance vehicles so expensive that they price the consumer out of their purchase. B.) DEF/EGR systems, neutering horsepower, reliability, all while increasing operating costs and repairs. C.) Registration fees that are more for large vehicles.

Just a few random examples.

Nonetheless, every fanatical anti-EV statement on the forum (not saying you were one of them) focuses on an extraordinary case as a strawman to debunk EVs. Hauling 32 hours straight through -40 degree weather with 12,000 pound trailer uphills both ways sort of anecdotes. That use case is never going to be the primary utility of an EV and they aren't even planning/designing an EV for that tiny segment of buyers so its a nothingburger.

The supermajority of all people in the US drive <40 miles a day. The average American has visited only 17 States in their entire life by all means of transportation. <- That's 80% of the EV market. Only recently have they attempted to cater to alternative market segments (e.g. Cyber Truck) which hasn't even been released yet.

By 2040 EVs will actually be the far, far better vehicle that oil driven vehicles, but it requires one of two technology breakthroughs. 1.) Slow drain capacitors, which would be 1/10th the weight which in turn would allow people to drive around with 1500 mile capacities. OR 2.) Carbon based batteries that are lighter in weight and do not require rare earth metals. One or both will be in production in our lifetime because rare earth battery demand is not sustainable, its only a necessary evil at the present.

We're literally at the point of EVs where computers were when windows 95 came out. Functional, sorta, with viability for some customers, but most of the readers here weren't ready to get a home PC when that was the operating system you had to endure.

First let me say that I'm neither an EV hater or promoter. EVs I believe are here to stay and as an engineer I tend to always believe there is room for improvement in anything and especially when technology is in its infancy which I believe is where we are currently at in regards to electric vehicles.

Now setting aside my personal view of the various pros and cons of current electric vehicles of which I think there are many of both, I don't know about this so called slow drain capacitor. With all due respect that sounds familiar to the flux capacitor which was the miracle gadget that made time travel possible in the movie Back to The Future.

Call me closed minded, but I was taught in electrical engineering the following in regards to capacitor physics:

I = C dV/dT where

I = current
C = capacitance
V = voltage
T = time
dV/dT = Rate of discharge/charge of voltage

Solving for dV/dT (rate of voltage dishcarge/charge) = I / C

I have a lifetime of empirically proving this over and over again.

So there's only two ways to affect the voltage charge / discharge rate and that's to either change the current load/source or change the value of the capacitance.

Reducing the current load would have the same effect on battery discharge and allow for longer distance between charging. So I'm not sure how that would make capacitors a better solution than batteries.

However increasing the capacitance is a different story. The very word implies this, more capacitance implies a larger capacity of energy storage. And this may be a solution. If you could in fact greatly increase the capacitance to hold energy such that it exceeds that of batteries for the same amount of weight/physical space or even less, than that could make it a possible solution.

In the end it's not about a fast or a slow rate, it's about energy. For this comparison of a capacitor to a battery, the comparison should be about comparing the energy storage of one to the other.

A side note, capacitor voltage charge/discharge rate is linear. As soon as a current load or source is applied to the capacitor, the voltage will decrease/increase linearly. Batteries on the other hand tend to hold their voltage at a fairly constant level until they get close to depletion. This means an EV being powered by a capacitor would likely need more complex voltage regulators.

I'm not meaning to split hairs here, but I've just never heard of a slow discharge capacitor.

@PHOENIX PHIL I'm not an EE like yourself, but I've followed the technology with great interest. Your facts are indeed, facts. Here's what I know second hand:

In about 2001 there was a documentary called "who killed the electric car?". (remember EVs came and went in the early 2000s?) There was a scientist that was working on these technologies, last name started with an O. He did have some patents which were ultimately bought by Chevron. You can dig into that a bit if you wish. The other anecdote was an article I believe in Forbes or Fortune in the early 2000s about the top-10 or top-20 technologies that will revolutionize the 21st century. One on that list was the possibility of slow-drain capacitors and they interviewed those working on potential designs.

What has come out recently was theoretical designs for a battery built on purely carbon technologies. Obviously, carbon is very cheap and its weight as an element is far less than rare earth metals. They think this technology may evolve faster than the slow drain capacitor + voltage regulator scenario in the first paragraph.

I'm just a curious consumer that takes particular interest in this topic because I believe present battery technology dependence is a national security risk. (Russia/China control the raw materials) Current battery technology also makes for very heavy vehicles, whereas the two potential technologies I mention above would have aerospace uses as well as cars due to their lighter weight.

Could Ultracapacitors Replace Batteries in Future Electric Vehicles?

Ultracapacitors have been making the news of late but could they viably replace batteries in the EVs of the future?

This is the error or belief regarding the government. The government can give you NOTHING for free. The govt can only take from one and give it to another because the government produces nothing. The govt can print money, but all that does is dilute the value of the products and services that someone made.

This morning, on market day guaranteeing maximum civilian presence, the Russians struck the city center with an Iskander tactical missile with a thousand pound conventional warhead.

This is pure savagery designed solely to try and terrorize the civilian population.

It would seem that someone would learn a lesson from previous attempts to obtain submission by terror. History shows that attempts to control by terror result in the opposite reaction. The citizenry being terrorized further strengthens their resolve to resist. The warhead may have killed a hundred people but it galvanized the resolve of several thousand against the Russians. With the deaths and injuries of friends and family the residents now had skin in the game and were no longer indifferent.
