Not only that but AFAIK no current EV can do wireless charging so who do they expect to use this? I should probably read the article.
Comment on Detroit's newest road can charge electric cars as they drive on it

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

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.

Sounds like the next step is to power it using renewables so that we reduce that inefficiency as low as possible
RGB3x3@lemmy.world 6 months ago
It didn’t reduce the inefficiency though. You still have 50% of that power being lost, which means you need 50% more renewable generation. It’s wasteful.

Yeah and who uses the energy that is lost? Nobody. It’s not a 50% loss to a driver, it’s all gain over the last charge stop.
As someone who did 500 miles this last week in an EV with 2 little kids, let me tell you it would be fucking worth it not to interrupt my sleeping children even if it’s not 100% efficient.

Electricity isn’t free. Convenience doesn’t make things a good idea nor economically viable. Need to charge on the go? Overhead catenary charging is a technology that’s already developed for use on vehicles and solves the efficiency issue.

I actually make a yearly pilgrimage of 500 miles and apart from gas stops I go nonstop, no breaks. I find that making numerous stops wears me out and I start to fall asleep in the last couple hours. Could easily be because I’m adding hours to my drive if that’s the case though.
