Qualcomm's dynamic EV charging thing.... (really)?

[peteb2]

So i'm sorry, i admit to not having seen anything of this simply because it's not an area i work in plus there hasn't been any obvious massive promotion. I only discovered things happening (and Qualcomm) as a link to this You Tube video (link below) appeared as a unsolicited bit of advertising upon my Facebook.

I'm a New Zealander and it's very interesting this video is all about some great big breakthrough that's happened, and it looks as if it's all occurred in NZ, but i cannot find if that is truly the case.

The footage of a vehicle being driven sedately and perfectly in a specific position no doubt down a short strip of a special piece of roadway looks like it's in the UK.... so i am even more confused.

Finally i'm just wondering... how would it ever be feasible to maintain a roadway containing these sorts of "electrics" to charge any EV especially a freeway or motorway when we already see that roadways suffer hell just from the vehicle flow volumes and cost incredibly large amounts of money just to be maintained let alone have 'electrics' inserted into the centre (and the reduced traction that might result etc etc)...

It all kind of mirror's Dave's thoughts on having those ridiculous solar highways  as what i see as the Big Corporates jump on the Greeny, Save the Planet, Crude Oil runs out soon, Climate Change Bandwagon to establish their positions in the hope of huge hopeful Profits...

Anyhoo... as they say here's that YouTube:

Well, if they've got that many millions to throw around in development, sure, why not spend a few more installing a couple thousand inverter modules per km?

I would be worried that the amount of power transfer would -- besides potentially melting vehicle chassis and wheels -- push so hard that the vehicle is pushed off the track or loses control.  It would feel weird, regardless.

Electromagnetic propulsion (a linear motor) is effective for tracked vehicles, especially where the electronics are on the vehicle, not the track (meanwhile, the track is fairly passive, like a copper plate, give or take a laminated steel "squirrel cage").

Can it be done?  Sure.  Will it be done?  No.

Did you have the sound turned off when you played the video?  It is explained.

You must have some kind of auto-interpretation device so good for you but you've absolutely missed my entire point.

"We split the project into three phases, first of all the concept, design and prototyping here in Auckland, and then the industrialisation and manufacturing in Munich, finally the installation and testing at the fabric [?*] site in [notsure*] Paris"

"[...] completed the concept design here in Auckland we provided the designs through to the engineering team in Munich who would produce the hardware [...]"

"The demonstration track at fabric..."


My only "auto-interpretation device" is my ears.


*: 2 seconds Google, "100-meter FABRIC test track, which has been built by Vedecom at Satory, Versailles, near Paris"

Edit: Googled the bits I wasn't sure I heard right, * above.

started a thread two weeks ago about the same project.

FABRIC is a €9 million project, mostly funded by the European Commission, addressing the technological feasibility, economic viability, and socio-environmental sustainability of wireless DEVC.

A complete waste of 9 million € (for R&D). They can make an other charging track in a larger scale but i can't see how this concept could be generalized with reasonable cost.

My question was how efficient will it be, say if it's 80% efficient this mean 20% of energy is lost, considering the size of such system (complete roadway) that's a lot of energy wasted.

So they are pissing away taxpayers money provided by idiot politicians - explains everything.
