Reminds me of high-speed rail being propelled by magnets.

Railgun - Wikipedia

I read a proposal a while back to build one of these on a mountain in the Andes to propel things into earth orbit, or at least get stuff high enough to save on rocket fuel.

It sounded good, but like many such things there apparently is a real problem, probably $$$.

Wireless EV charging gets a boost: Single standard will harmonize systems up to 11 kw (greencarreports.com)



This is for parked cars, but might someday apply to moving vehicles.

Our stove uses a related principle to heat pots, inductive cooking, which to me is the greatest thing since bread was first sliced by my cousin.

Stuttgart researchers develop inductive charging of EVs in motion | FierceElectronics

I'm a bit optimistic about this approach, but it's decades out I think.  The concept is great, I envision freeways with induction lanes for EVs.  You'd arrive near your destination and exit the freeway and use batteries to drive wherever, and then park and recharge without hookups.  The losses are an issue.

It almost eliminates range concerns.

Like I said way back - like Minority Report.

More akin to Speed, I think, or Bull Durham.

Yeah, wireless charging as a technology exists and would work. It's inefficient and wasteful, however. That's not a huge issue for a cell phone, but become a real economic problem for a vehicle.

Just wait for the solar-powered drones that can carry a person.......

You can do calculations obviously based on whether this could work even at 100% efficiency.  It's not pretty.

As for inductive charging, it might someday be efficient enough if EVs lowered some kind of charging plate very close to the coils.  

Our stove starts humming on the highest settings, I'm not sure why.  I have wondered if it's generating much RF.

EVs To Be Biggest Revolution In Cars Since 1913, Says BBC (insideevs.com)

So how fast will electric cars go mainstream? "The answer is very fast. Like the internet in the 90s, the electric car market is already growing exponentially. Global sales of electric cars raced forward in 2020, rising by 43% to a total of 3.2m, despite overall car sales slumping by a fifth during the coronavirus pandemic," reports the BBC.

According to Rowlett, "We are in the middle of the biggest revolution in motoring since Henry Ford's first production line started turning back in 1913."
Want more proof? "The world's big car makers think [so]... General Motors says it will make only electric vehicles by 2035, Ford says all vehicles sold in Europe will be electric by 2030 and VW says 70% of its sales will be electric by 2030."
And the world's luxury automakers are also getting in on the action: "Jaguar plans to sell only electric cars from 2025, Volvo from 2030 and [recently] the British sportscar company Lotus said it would follow suit, selling only electric models from 2028."


I find this a bit misleading and uninformative personally, no effort to make projections here.  If sales rise 43% off a very low figure it doesn't mean much unless it continues apace year after year after year.  And what factors might slow that pace?

There are a lot of rich people in China.

While Jag-Land Rover still isn't what you'd call reliable, I think the Indians brought in some build quality and engineering/production know how to the company.

Jag has some really nice looking cars, and they are liked by folks who want something other than the usual.
