Sounds like grocery getter pickups for now vs long trip towing vehicles. Nothing wrong with getting groceries.

The charging stations could have local power storage. I read an article not long ago about using flywheels to store energy. A big flywheel can store an impressive amount of power, and release it quickly for a 20 minute charge. Then it could gradually spin up again, stabilizing the load on the grid.

50+ years ago there was talk of using a flywheel method to power city buses. They come in handy on a hay baler with a small tractor as well.

Molecular Machines: NanoGear – Mechanics of the Infinitely Small

While Italy has been a leader in the minds of many of us "gear heads" they are taking the concept of gears out of human sight. Just wrapping our heads around buying a car without a gas tank, transmission or starter is huge and now this.

250,000 to 350000 watts chargers. holy crap, how is the power grid supposed to support this.

What are you, an electrician or something ?

l'll pick on the obvious target, Cali. Today, the wind blows, and they can't/won't keep the grid up.

Waive the Magic Wand, and that problem goes away.....

Brownouts or worse during heatwaves are not unheard of...... M Wand time again.

USA is well ahead of us right now (I sit here, locked down under Wuhan War III at the moment....), so let's use the M Wand one more time and pretend that people and holiday and traffic patterns return to normal....

It's coming up to July 04 long weekend, and the M Wand has held off all those other issues in LA. Thursday night, a million or so fractional MegaWatt chargers plug in, to get ready for the holiday weekend drive.....

No Worries, wave the M Wand one more time...... and give the LA grid Viagra.....

I guess the best thing to do is when he visits you with his gasoline/diesel vehicle go ahead and fill up his tank. That is what people did in remote areas before filling stations were everywhere and you lived very remotely. I learned this from the tour guide in a remote Lake Tahoe Nevada Mansion when guest from the California coast would visit. (Just a hundred years ago . . . .)

Time always Rolls Along....

None of us were alive when gas engines debuted..... gas was so scarce in some areas, you went to a pharmacy, druggist, apothecary to get fuel...

Lots to learn, from actual History....

Did Ford just damage their chance of long term success by suggesting the Lighting is light years ahead of the F150's on their lots today?

I often listen to this guy from Denmark.

Interesting video.

You'd think Osborne would be required Marketing 101 reading.... but I'm getting old, and tend to forget, people don't read anymore....

While there is no shortage of public Virtue Signalling on the horizon any time soon, it's a bit surprising that Ford went as far as they did, trash-talking their present (and pretty much only) golden-goose.

Detroit has long regarded small car ICE production as a losing game, and Ford killed most of their traditional car production some time back.

Elon's evangelical style works, but folks and companies should think carefully, before blindly adopting same....

Reading on electricity in Denmark....

Electricity sector in Denmark - Wikipedia

Denmark is a net importer of electricity. The flow of electricity between Denmark and the countries it has interconnectors with (Norway, Sweden, Germany and the Netherlands), and the direction of that flow, is highly variable and depends on current demand and current Danish wind power output.

Danish average consumption of electricity per person was 0.8 MWh less than EU 15 average in 2008. Denmark has average electricity costs (including costs for cleaner energy) in EU,[2] but general taxes increase the price to the highest in Europe.[3] In 2015, supply security was over 99.99%, among the highest in the world.[4]
