Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

That's not in the cable, that's the "end to end" charging system, and yes, that is comparable to wired charging. Efficiency in the wireless transmission is 96-99%, depending on distance and alignment. This has been studied extensively. Like I said, this is not new technology. Have a web search.
Here's a couple articles to get you started:

https://www.mckinsey.com/industries/automotive-and-assembly/our-insights/perspectives-on-wireless-and-automated-charging-for-electric-vehicles#%3A%7E%3Atext=A+wireless+inductive+charging+system+is+at+least+one+or+two+percentage+points+more+efficient+than+a+DC+%5Bdirect+current%5D+fast+charger+at+the+same+power+level.
So that whole wall of text had one source that showed 4% losses in a lab with coils really close together, which is still a lot more loss than a copper conducter.
The marketing hype basically says if you factor in all of the losses from the power generation and transmission all the way to the wall then our additional 10% loss is no big deal so you can ignore that 1kW of lost heat you have to pay for on top of the grid's losses that are already a part of your costs.
If you don't like my sources, feel free to find your own, they all say the same thing. There is no additional 10% loss. You even ackkowledged that in your reply, then came back and reported it again. What's that about?
This is why misinformation is so hard to deal with, i put in effort to read and assess what you provided and found that you came to the wrong conclusion even with the sources YOU provided and now you want me to find even more evidence that you will just ignore? Nah, your mind is already made up, you ate the marketing hype and no amount of data will sway you.
That fist article actually has some interesting concepts that dont really apply to a pad on your driveway but like if the infrastructure was kinda everywhere then you could have smaller batteries, keep the charge in the sweet spot further reducing capital costs and keep your fleet trucking and not idling at a charger reducing opcosts. Neat. Maybe we'll get there some day.
Good on ya for not feeding the trolls.
Ah yes, "the trolls", those assholes that always show up with facts and half a dozen sources and then invite you to educate yourself more!
Sick maymay bro
This is why misinformation is so hard to deal with. I put in effort to find a half a dozen sources and highlight the relevant sections and you dismiss them outright because you don't like them, but you can't be bothered to do so much as a web search to inform yourself.
You don't want to learn, that's not something I can do for you.
