It makes me wonder, how long will it be before such inept misinformation ceases to have traction?

The debate has not moved on much in the last year, in terms of the BS posted.

The "facts" have m ...

I'm content in the belief that lithium and sodium (touch wood) have 95% of transport covered.
All further development is icing on the cake.

Plenty of potential for green energy if we can be bothered to do anything about it:

For us towing a full trailer of logs would be essential. Basically we need a workhorse.

My guess is that as batteries get cheap, rather than gears in the EVs, we will see batteries in the trailers.

I'd probably be a light user by most standards, but when I do need to tow then we're taking a full load a few hours on rough roads.

Towing remains a weakness as EVs don't on the whole have gears. ...

Don't need a rear differential if each wheel has it's own integrated motor. That's one of the approaches being considered... Frees up the rest of the vehicle to be whatever you want it to be, so long ...

I certainly wouldn't trust this company blindly.
but.... The 800v architecture of an Ioniq 5 already allows for fast charging to go from 10 to 80% in less than 18 minutes, at a 350kw charger.

Presumably if it was 3 minutes, it would be less cars needing to charge at anyone time which would balance things out.
Doesn't alter the other points though.

Big claim being made by Prieto which says their new batteries charge from zero to 100% in 3 minutes.
Scrutiny will be important, but if they can deliver that changes everything
