New technology installed beneath Detroit street can charge electric vehicles as they drive

Crews have installed what's billed as the nation's first wireless-charging public roadway for electric vehicles beneath a street just west of downtown Detroit.

Copper inductive charging coils allow vehicles equipped with receivers to charge up their batteries while driving, idling or parking above the coils.

The quarter-mile segment of 14th Street will be used to test and perfect the technology ahead of making it available to the public within a few years, according to the Michigan Department of Transportation.

Demonstrations were held Wednesday at Michigan Central innovation district, a hub for advancing technologies and programs that address barriers to mobility. The district also is where Ford Motor Co. is restoring the old Michigan Central train station to develop self-driving vehicles.

there's this

One mile of Detroit's wireless EV charging road to cost at least $1.9 million

Makes hydrogen stations seem much more affordable

And those that say a H2 infrastructure must be built from scratch haven't been to Germany

by digging up every roadway in the US?

don't blow up.

Believe it or not every hydrogen car on the road has actually been crash tested

and hydrogen doesn't explode until or unless it's mixed with 02

A million and 900,000 dollars a mile

The state of Michigan will spend $1.9 million to build a one-mile stretch of the nation’s first public wireless in-road charging system for electric vehicles (EV) in Detroit.

before revising the cost which might happen a few times on a brand new project like this

Ridiculous. But for some, literally anything but H2.

Here's someone who has lived off the grid (and fueled his hydrogen cars) since 2006.

The "revenue stream" argument from hydrogen bashers is a tactic to push big 1,300 pound not-anywhere-near-green batteries on everyone that buys a car.

Not sustainable. Especially since every single battery in every single BEV will die and need replacement

people that just will not listen or learn because they love lithium batteries

If that looks like an ICE you just might admit to yourself you're unfamiliar with the topic

Not a youtube vid, but you may find it interesting nonetheless:

It's unlikely FCEVs will overtake battery EVs simply because of the lower efficiency.

For the foreseeable future, there won't be one size fits all. I don't see a trucker in the frozen north giving up a huge chunk of payload capacity for a battery powered vehicle, but at the same time, even using lead-acid batteries, 80% of commuters could have been running on battery power for decades. That might have given us more of a CO2 cushion to tackle industrial greenhouse gases.

The article does say that Michigan is working on the revenue model.

You cite Germany as a country that has an H₂ infrastructure. Yet the article says that Electreon has a contract to install this in Germany:

The technology belongs to Electreon, an Israel-based developer of wireless charging solutions for electric vehicles. The company has contracts for similar roadways in Israel, Sweden, Italy and Germany. The pilot initiative in Michigan was announced in 2021 by Michigan Gov. Gretchen Whitmer.

I don't think we know exactly how the infrastructure that supports EVs will ultimately look. There may well be multiple options available.
