Sounds like an investment opportunity, eh?

Yep got a smile. I’m not observant a lot of the time. But
it is out plain to see. Thanks.
“Electric cars are already going 450-500 miles and new batteries coming out fully charge in 5 minutes or less.”
Let me guess, in “development”?
And tell me, where do you find a place to deliver .5 MWH (rough BTU equivalent of 15 gal of gasoline) in 5 minutes?
That’s 12,000 amps at 480v.
Got any links to share this miracle of engineering with us?

Posting this again as, apparently, I need to.
People have no concept of what power flow requirements are needed to fill up multiple batteries at the rate necessary to equal the driving range and fill time of a typical gas powered car.
15 gallons of gas is equivalent to about half (.495) a MWH. That means to fill an equivalent battery in 15 minutes (a very long fill up time at best) you’d need to pump in energy at a rate of 2 MW per car.
For a small 8 pump filling station that’s a capacity of 16 MW. We’d need that much electrical transmission capacity, or more, going to nearly every filling station in the country.
The country’s entire electrical distribution system would need to be replaced from the ground up with one capable of orders of magnitude more power generation and transmission.
Replaced.
It is flat out not possible to upgrade the current system to meet that need.
Not going to happen.
As I've mentioned in other responses, estimates are that EV's will at best only be 25 percent of the vehicle market in 2035. Even then, it's going to be hard to generate the electricity required to charge them. But Tesla is ahead of all the other wannabe EV makers, as Tesla also is supplying energy for their car buyers. Tesla builds solar panels, home energy storage panels, and partners with utility providers by building large energy storage systems. There's one nearby in Monterey county, a 182.5-megawatt (MW) lithium-ion battery energy storage system built for PG&E. So Tesla is providing electricity for their cars. Other car makers have little or no plans to do so.
Also, Elon Musk says he will not continue selling EV cars in the near future; his plans are for robo-taxis. Musk is the only realist among the EV sellers. As you said, not enough electricity for everyone.
Israeli company Sourcedot invented the 5 minute battery. It can go for 100 miles. It is currently being made in China
Please invent something that does not make ground contact, has collision avoidance, and can use current streets as guides. Nuclear must be involved. Kill the grid.
“Israeli company Sourcedot invented the 5 minute battery. It can go for 100 miles.”
Inventing or making the battery is not the issue. Assuming this battery has to supply 10KW hours to run the car, which would be a real small car, you would have to charge it at a rate of 120KW for 5 minutes in order to charge it. One KW is about 10 amps at 120 volts. That would be 1200 amps at 120V or 600 amps at 240V.
The electrical service for your house is probably 100 Amp or 200 amp service. See the problem?
You'd probably have to get a much heavier electric cord:
“... and new batteries coming out fully charge in 5 minutes or less.”
Dude...seriously...that’s complete BS. And that’s coming from a guy that will buy an electric car.
Saying stuff like that just makes you look like a fool.
Hahahahaha...that was a great description-I got the flavor right away...being on the side of the road...helpless...
When that happened to me, I was driving in to pick up my fiancee who was returning from a Nursing conference down in New Orleans. I had to wander around Logan Airport with three antifreeze containers and fill them with water from drinking fountains. I nursed the car back home with her with me, but when I shut it off, it never started up again.
I’m sure those valves were all bent to sh*t...
Bingo
I will (almost for sure) buy an all electric Ford Mustang Mach E SUV this year.
Unless I get “Bidened”, $7,500 tax credit. Full write off as I own a business. Work is a 15 minute commute for me, and the charging system can work just fine off of a 20 amp 110 line in my garage. 8 to 10 miles per hour charge time.
Of course, this will be in addition to other gasoline cars that will last me longer as a result. The short commute is the worst on cars.
Screw electric cars they suck ass
Try them When your way out in the desert. Or it’s -20 degrees
I did my undergrad thesis on hydrogen vehicles. 1992. Berkeley

As others have pointed out, that has no relevance to your earlier statement about a car traveling 450-500 miles on a 5 minute charge.
If this vehicle and charging system exists, this is the best kept secret in the world of physics, mechanical, chemical and electrical engineering for all of history.
Link please!
Yes. The power lines alone would require unimaginable amounts of aluminum along with steel, carbon and glass fiber, and aluminum production needs monstrous amounts of energy. Towers and poles would be needed, also requiring extreme amounts of aluminum and wood. The revenues or even debts needed for such a project would be unobtainable.
What the EV advocates don’t tell you is that we don’t have the electrical system capacity (generation, transmission and distribution) to shift the energy delivered at the gas pump to delivery by the electrical system.
To use your numbers, in the time of 15 minutes, you need something like 100-350 kW capacity to charge an EV for 400 miles travel. That’s between 25-87.5 kWh. For comparison an average home uses around 1,000 kWh per MONTH.
Call me skeptical. Do you have a link to anything that might support this?
I’ve tried to ask people how much new batteries cost and I usually get a vague answer like, “They’re not too bad”. Hell, $4000 is the cost of a new engine or transmission.
