Really? Can you add something to substantiate that comment?

Re: the "grid storage" issue.

1. The electrical supply is not 100% stable. There are substantial voltage fluctuations in any 24 hour period. Line stabilizers are needed to shield sensitive equipment from voltage sags and spikes.

2. Demand is predictable. In that same 24 hour period, people get up, shower, turn up the heat, and go to work. Temperature forecasts are a good predictor of heating and cooling load. Wind forecasts tell you how your wind turbines will perform, overcast conditions affect solar arrays, and power system management tracks all available factors. Flexible generation capacity can be brought online on a daily schedule. Natural gas turbines can be brought online in minutes. Hydro turbines are right behind, limited only by how fast they can open the penstock without blowing the power house apart.

3. While household electrical demand is constant within predictable limits, major industrial users have to coordinate with their power suppliers before they start up major equipment like steel induction furnaces. Except in emergency, they will also coordinate shutdown.

4. The only real time online storage is inertial. Increasing load on a generator will cause it to slow down, but there is spinning mass, sometimes substantial, that resists slowing. Utilities generally keep the resulting voltage sag within 5%. Anything over 10% is a brownout. 1% to 2% is negligible. Let's hear it for angular momentum. Likewise, a generator can be spun up and ready, but uses very little power until it actually generates some.

Oh, and you notice I don't use the 'G' word, which is nonsense noise.

Roads That Charge Electric Cars Wirelessly Are Springing Up Everywhere!

Thanks to several companies and research teams worldwide, we could have roads that keep EVs' batteries juiced up within the decade.

You found it, apparently already thought of.
I bet it's the way things will go.

Ford confirms F-150 Lightning EV battery pack details, range estimates

Range and efficiency numbers for the F-150 Lightning are looking close to those of the Rivian R1T—but the Lightning is larger.

The Lightening will most assuredly change some opinions when it hits the road.

Semantics is about the only play for many to come and play in the sand box, I agree.

Obviously.

Building roads would become cost prohibited for cities. Then what happens when a pot hole shuts down 5 o'clock rush hour with everyone stranded with dead batteries?

If building a grid above ground is challenging, imagine putting it in a road.

So let’s do nothing. Don’t worry, other countries will figure it out, just like they have health care, and get it done. This will not be America’s century, we’ll be too busy arguing about it and modifying our pickup’s chips so we can roll coal.

A pothole, just like a dead coil wouldn't be relevant. The EV would still have batteries, it's just that the range wouldn't need to be that much...100 miles on just battery would be plenty.
I'm sure Interstates would be the first modification, then highways, smaller roads, etc.
Sweden is already working on electric roads, but to me I think of slot cars we had in the 60s. Induction, although not extremely efficient seems like even small charging mile after mile would add up as you drive.
I'm just thinking...

I will say it again, electric cars don't make sense right now. Ditch the concept all together. Turn the focus to residential and commercial solar capture with battery storage. Scale to the load as needed. Alleviate the stress to the grid, then you don't have to build it out in the future.

It makes no sense to force a square peg into a round hole. Trying to electrify transportation requires downtime to charge at specific locations. Industry is not going to slow down for charging when there are super fast and convenient alternatives available and proven. It defies all economic laws, it's not sustainable in the long run.

Which brings us to the elephant in the room...batteries. They're not there yet. They need to store about 10x more energy before it makes economic sense in a car. I'm sure we'll get there, and then accommodate the tech.

Is it really going to end all days if we are behind some other countries on electric cars? I’m sure we can still conduct commerce with ICEVs until we catch up, if we even want to.

Remember the fear and panic created when Russia was going to beat us into space? Then what happened? All the fear and panic stopped when we stuck a landing on a place called the Moon.
For like 50 years, nobody else ever did make it there, did they?
So communist China with their 1 child per family and 1.3 billion people crammed into their country has EVs before us. They still have a lot of problems we don’t have, but we feel “left behind” because they have more EVs per capita than us?

I‘d rather live here and ride a horse or drive a Cummins than China with an EV. You can throw a lot more countries into that group as well. Not ALL advancements in technology are “advancements”. Some are needless and just a race to the bottom while creating needless expenditures when in reality, America’s bank account is empty.

Plug In or Gas Up? Why Driving on Electricity is Better than Gasoline

Electricity power plant emissions data and the latest assessments of fuel emissions and vehicle efficiency show 97 percent of people in the US live where driving an EV would produce fewer emissions than a 50 mpg gasoline car.

Yuck!

 

[Gale Hawkins]

Here is the EV power source some of you have been clamoring for.

 

[Agvg]

This will be very common, most large cities in the world don't have space for privat ownership of cars, cars that take up space and almost never being used.

 

[Egon]

It surely can store energy...I will give you an example.

I was the economist on the board for our electric company when Amazon and Microsoft wanted to open a series of server farms here. These require so much energy to operate and chose Wyoming for it's cheap power (coal) and access to fiber optic distribution lines. My committee on the board was tasked with figuring out the load factoring and if there was enough capacity to operate these places in both peak and off peak times. Well there was not enough capacity. The bottle neck was not at the source of generation, but the capacity in the high tension cable distribution network. In order to supply the energy those companies needed, we had to add another high tension wire line to add storage capacity for times of high demand.

So...

Transferring energy. Shut down the generating station and the line will be dead. Lines are often isolated to work on them. They do not retain a storage of electricity.

There are many transportation methods/systems using externally generated electricity. No batteries Required.
