Detroit is now home to the country's first chunk of road that can wirelessly charge an electric vehicle (EV), whether it's parked or moving.

Why it matters: Wireless charging on an electrified roadway could remove one of the biggest hassles of owning an EV: the need to stop and plug in regularly.

Americans will literally do anything to not build trains

[–] RagingRobot@lemmy.world 8 points 1 year ago

I would love to have both. Especially trains! The trains here are so bad though. They cost more than flying and are such a hassle to deal with. The train stations are sometimes far away from the city in some cases too. So you need a ride from the station.

I would support building that out if it was offered.

EEVBlog, Dave, where you at? We need a debunking video. This smells like solar freakin' roadways.

[–] frezik@midwest.social 7 points 1 year ago* (last edited 1 year ago) (2 children)

It's not as bad as solar roadways, but it's still a meh idea. It works, but it's not very efficient. You need coils of wire built into the road, which means replacing the concrete. Still need to upgrade the power grid to handle the load. If it's not 100% tax subsidized, then it has to track where you're car is in order to charge you properly.

It solves few problems and adds some of its own.

Why occasionally plug in when you can lose roughly 50% efficiency and not. Such a boondoggle.

[–] KairuByte@lemmy.dbzer0.com 13 points 1 year ago (2 children)

The point would not be to never plug in, but instead extend the drive time of an EV by using certain roads.

If on a full charge you get 250miles, but if you take a slightly alternative route and get 500 miles, you’re going to have much less resistance to EVs in any community that would be likely to use these roads.

[–] BearOfaTime@lemm.ee 7 points 1 year ago (7 children)

You missed the 50% loss. Wasted energy. Means you have more infrastructure delivering electricity that isn't utilized. Means you have more production that isn't utilized.

And batteries already have a loss of up to 20% during charge from heating.

You’re human, I’m human, and almost anyone buying an EV is presumably human (I hope) So I can confidently say this from experience:

In 250 miles of driving, it’s very likely you’re going to need to take a dump, a pee break, or grab a sandwich. If you have a second passenger, even doing so twice or three times.

15 mins for stops isn’t bad at all, and more people need to understand their “quick stops” that feel like 1-3 minutes are actually a lot longer.

More often than not, I’ve found my car is ready to go before I am if I am ordering a coffee or grabbing a fast food item and taking a quick pee break.

Source: owning an EV and doing 6 600mi trips and 2 250mi trips.

Goddamn we can't even maintain the basic roads we have, much less a much more expensive and complicated one. It'll be obliterated by salt and snow the first winter and never work again.

[–] Kolanaki@yiffit.net 6 points 1 year ago

I can just imagine all the tweakers tearing up the road to get at any copper wiring it might be using.

Now when will the capitalism kick in and if you don't pay your monthly sub you don't get road charging

[–] SCB@lemmy.world 9 points 1 year ago (1 children)

Roads are paid for via taxes

Why would you expect something like that to be free or even one-time payment?

Electricity definitely cost money even when the city or state pay for the infrastructure, which is really unlikely.

Financially or electrically?

[–] cmnybo@discuss.tchncs.de 14 points 1 year ago (3 children)

That sounds like it would be very inefficient and produce massive amounts of RFI.

Kinda like F-Zero?

You know what other form of transportation wirelessly recieves power? Trains.

[–] Gsus4@mander.xyz 7 points 1 year ago

Wirelessly?

Charging keeps getting presented as a major hassle but it really really isn't. Trickle charge overnight is more than plenty for a day of driving.
