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 7 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.

[–] bonobi@lemmy.world 11 points 1 year ago

I thought the same thing!

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 20 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.

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.

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.

[–] luthis@lemmy.nz 22 points 1 year ago (1 children)

Financially or electrically?

[–] pastabatman@lemmy.world 20 points 1 year ago

There's a lot of details missing here. It sort of makes sense if you are parked on the street, but it says you can also get a charge while driving. How much battery capacity can you realistically expect to get driving down this stretch of road? Like within the limitations of physics. Maybe if the highway system had this installed but it would be outrageously expensive to replace it all. I also have major doubts that a universal standard would be agreed upon by all manufacturers and municipalities.

Money would be better spent installing more frequent charging stations, which I understand is already the plan.

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 10 points 1 year ago (5 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.

Kinda like F-Zero?

[–] cmnybo@discuss.tchncs.de 10 points 1 year ago

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

[–] TropicalDingdong@lemmy.world 10 points 1 year ago (1 children)

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.

[–] NoIWontPickaName@kbin.social 7 points 1 year ago (3 children)

This is America son, I can drive 11 hours a day and still be in the same state.
