Batteries and etc.
And you haven’t provided references for your claims.
You still demonstrate that you haven’t bothered reading any of the links.

A battery has a maximum theoretical yield of 100% of production energy.
A gallon of gas has has a maximum theoretical yield of 1000% of production energy.
I’ve read them and others 1000s times. They do little to solve the issue of how we move the winter wheat from Russia to Europe as cheaply as we do now. How do we ship the goods we get from China?
Where do I get my energy when I’m not at home and hooked to the grid?
And if you read them, you’d also know that all these sources of energy still require a conventional backup for when - you guessed it - the wind doesn’t blow or it’s cloudy for several days.

There is going to energy loss. But that’s not relevant because the aggregate supply/storage is what matters more.
And I’m the President of Switzerland.

The solution is moar batteries!
A lower yield supports a smaller population. That’s really all there is to it.

Batteries are the most important. But pumped-storage dams help too as an example. Minor but it shows the diversity of ideas and existing techniques that will help us.
You keep claiming lower yield but no citations.

I wonder how big a battery you’d need to run this near capacity;
(Please Note: This uploaded content is no longer available.)
I also wonder what percentage of the capacity the battery itself would occupy and if there’s some interplay like the square-cube law where the appropriate battery for near-capacity use of any meaningful duration would exceed the work capacity of the vehicle.

The road trains can’t stop for the olympic charging durations they’d require. The economy of those vehicles can only be met by keeping them going.
You’d have to create battery-swap stations - for additional energy cost.

It really helps if you actually knew what you were talking about.

Sorry man. I come by it honest.
It’s just harder for me to have faith in things.
When someone tells me that batteries are going to save me, my default is “when I see it”. I’m old enough to have seen quite a few “NEXT BIG THINGS” go poof.

Again, about something as large as the mining truck, remember that it’s currently produced in a world that can harness the spare energy of fossil fuels.
Moving metal around will require much more (name removed by moderator)ut energy when you’re limited to a theoretical max output of 100%.

Did you read past the headline? The negative has to do with minor issues like smoothness. It’s not so much the concept.

Yeah. They admit it’s not really possible yet.
“Volvo hasn’t released pricing, but admits that convincing the trucking industry to give the new technology a chance will have its challenges. Financial hurdles aren’t just the costs of the trucks themselves, but also the price of infrastructure development. “We will need support with incentives to help adoption,” says Lars Stenqvist, chief technology officer for Volvo.”
Did you read it?

Again, as we transition away from fossil fuels, then the context will be different.
People don’t base their designs on theoretical 100%s, they go for lower than that to accomodate real life.

He didn’t say it, but I’ll bet my retirement he’s talking about battery-swap stations.
Good luck, Lars.

Those financial hurdles are an issue in the US.
At least I read your link. I not sure you even bothered watching that video considering the speed of your response.

The US has a lack of interest in greener tech. More interest in useless wars in the Middle East. The Europeans have a lot of interest in the environment seen in their tax incentives, regulations, goals, etc. Again, one of my links above suggests the issue is political will.Lol, sure.
Things don’t cost money in other places?
