25% EV Charging Stations in San Fran Region Don’t Work

What I am saying is that they are making progress towards having an affordable and viable product.

It seems to me the vision isn't to have an affordable and viable product but a total replacement of ICE vehicles.

Seems like a flawed vision to me.

You are certainly allowed to believe that. I doubt your opinion will change much though.

Just do the math. The annual global electricity consumption is ~580 million terajoules or about 13865 million tons of oil equivalents. (mtoe). The annual global crude oil production is ~4.2 billion metric tons.

Li-ion batteries have one of the highest energy densities of any battery technology today at ~265 Wh/kg.

Now factor in the battery back up storage needed for base-loading renewables and the need to replace all of it every 7 to 10 years. It's staggering. Can't be done.

Currently most wire being pulled in most buildings today is THHN or THWN which is good for 600 volts. Even the romex in your house can hold 600 volts. A little bit more insulation isn't going to be a huge issue.

Yes and I have a set of Klein insulated screwdrivers and pliers that are rated to 1000V. It all depends upon the dielectric constant of the insulator used, but would I seriously want to regularly run a high power 600V circuit through house wiring? The only way that wiring ever sees that kind of voltage is during a transient power spike, which, when you take in the usual crest or power factor of AC is why you need 600V insulation on a 120/220V line, not to run an actual 600 volts.

As usual, I've gotta tell you to take your vast knowledge to all the auto manufacturers who are investing millions of dollars in electric cars. As soon as they see how much smarter you are than they and all their engineers are, I'm sure they will reverse course. Imagine how greatful they will be for you setting them straight.

Who aren't the ones who have filled your head with something that can't be done. They are just gearing up for government mileage requirements which effectively mandate EV's to auto manufacturers.

But it's idiots like you who can't ask simple questions that are the root cause of the problem. The Utopian dream that has been sold to you is impossible. That is reality.

OK Here's a simple question just for you. Where did you get that stylish tinfoil hat?

Tesla is supposed to be coming out with a new truck. Now if his claims of performance are anywhere near true....it will be a game changer. 500 miles on a single charge...10 minutes of charging will get you another 300 miles or something like that.
800 volt system will radically change the dynamic of EVs.
Carbon Fibre wrapped motors and a new upgraded battery giving increased payload and towing capacity. (2,000 lbs)
Also a price tag starting at 40k. (IOW affordable for a change)

There's still going to be the issues of an insufficient power supply and the issues surrounding charging in disaster zones....but it definitely is very different than the original specs.
If they can overcome the issues surrounding apartment complex parking and charging....they might have a winner.

In my opinion....they need to radically change the way cars charge. Quit putting the juice on the end of the charger with a cord. Have the vehicles carry their own cord. It's not even difficult. Create a universal socket instead of a universal cord like the rest of the electric industry utilizes. Too much opportunity for failure the way its currently designed. DUH!

Towing capacity of 2000 lbs?
That's crap. About the same as a Ford Escort.
Most boats weigh more than that, and practically all campers double that.

23.9 billion metric tons of lithium are needed every 7 to 10 years.

Current lithium mining produces 86,000 metric tons per year.

So at our current rate of mining lithium it will only take 278,475 years to meet the current needs of a Utopian dream.

Is that towing capacity, or load capacity?

With as much profit as is made selling new cars, the majors will never let themselves be caught without a viable product. I get it. You don't think elctric cars are practical. Sorry, but I trust the opinion of major car manufacturers more than some goober who spent 15 minutes on Google to form his opinion.

I spent 5 minutes doing calculations too. And probably more like 5 minutes for the google searches on usage and conversion factors.

The goober is the fool that doesn't understand his own Utopian dream.

Here's the lineup of current EV trucks.
Notice the delivery numbers.

Oh it's far from perfect yet...

But it is improving to a reasonable extent where it's almost viable for people.

Wow. A more credible expert after a quarter of an hour than all those silly people who went to school for years. I should have encouraged my kid to spend a hour with Google, instead of all those years in med school. She would have upgraded my beach cabin for me by now, instead of having to wait for her to pay off all those student loans.

That's a poor excuse for not thinking for yourself. Like I said... it's just math.

Have any of those "silly people who went to school for years" told you they could produce enough lithium batteries to replace 88 million barrels of oil per day?

Or are you just assuming they can?

While you're there telling them that their plans just won't work, you can ask them.

Or are you just assuming they can?
