From the article -

Some not-so-fun facts about these rankings:

• Tesla is only the second product we have ever reviewed to receive all of our privacy “dings.” (The first was an AI chatbot we reviewed earlier this year.) What set them apart was earning the “untrustworthy AI” ding. The brand’s AI-powered autopilot was reportedly involved in 17 deaths and 736 crashes and is currently the subject of multiple government investigations.

That, and Tesla employees accessing your cameras - including the in-cabin ones - while you're driving around.

Every day it get closer. 600km 4wd and hmmm LDV concept which might come here

Saw a LDV ice ute at a Holden Motor dealer or Former Holden now Multi function place trying to get a part for M&Ds old holden I brought them. Saw a heap of the same ute with a MG badge in Thailand!

It is a tangled web!

This got my attention "According to the company’s translated press release, its semi-solid state battery – which features cell-to-chassis construction – affords the concept 1000km of range."

My Solid state favorite is really solid state and not starting until 2025 alas!

Are we there yet- NO

LDV ‘wants to offer 600KM range’

I want a new Range Rover Sport as a company car - it ain’t gunna happen though.

And although I’m looking forward to what solid state tech can do, to get from pretty much zero KM where we are basically now to 1000 is a big step.

I think this sort of thing, a car with electric driven wheels but with a motor and generator set is needed, until we have enough batteries, charging points, fuel cells, etc for everyone who wants one especially in vast Australia. I'm sure it will double the mileage, so halve fuel consumption or even better, if professional car companies work on refining the technology. I know there have been a few attempts, most famous was the Chevy Volt, which was even sold here, but car companies seem to want to keep ICE tech and I suppose larger engines mean larger parts and servicing costs, so larger profits. The guy in the video shows it is not that hard to do.

Years ago I saw articles suggesting that a small turbine running on almost any fuel and at constant revs was a very efficient way to keep a battery topped up.
Has business pursued that idea. If not,why?
At the time it was made to sound like quite an attractive proposition.

I have not seen this suggested, but the issues I would expect are that the smaller you make a turbine, the lower its efficiency (a fundamental issue with surface/volume problems due to losing heat), and the manufacturing cost of small turbines is very high - you need to have a very high temperature turbine with expensive and difficult to form parts. And the smaller the turbine, the closer the clearances need to be to maintain efficiency.

I am not saying it can't be done, just that it is not as easy to do as it sounds. And worth pointing out that even very large turbines struggle to reach the efficiency of current internal combustion piston engines. (In this discussion, efficiency means thermal efficiency - turbines are by far the most efficient if you look at power/weight or power/volume.)

Then there is the minor issue of meeting emissions rules, especially during startup. Should be no issues with NOx, but unburnt hydrocarbons and CO are another matter.

JLR had a turbine powered Jag concept car Jaguar C-X75 - Wikipedia and Jay Leno has a Chrysler turbine car in his collection, now might be the time for a comeback as the lead in petrol depositing on the fan blades caused it's early demise. Chrysler Turbine Car - Wikipedia

Very small gas turbine engines certainly exist - used to use a portable two person Rover Gas Turbine Firefighting water pump. Required two persons to start it - had to be hand cranked to very high revs to fire up and the first guy would be knackered before too long with all the hand cranking then the second person had to take over - sometimes it would fire up mostly not.

Not a great piece of kit.
