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

[–] [email protected] 24 points 1 year ago (16 children)

Trains are amazing for small countries, or between cities. The problem comes when you take into consideration how spread out the US is. You will always have cases where a car is needed, it’s unavoidable.

EVs are not a perfect solution, by a long shot. And ideally we would move away from cars being ubiquitous in America, but that is many, many years off. It’s better to work towards that slowly than it is to say “well it’s not perfect so let’s just not.”

You will always have cases where a car is needed, it’s unavoidable. That’s because it’s designed for cars. We have huge parking lots designed for cars but nothing for public transport. Whenever I travel to NYC or Chicago, I can go anywhere in trains and buses. In my city, I can’t even get milk without driving to a store.

[–] [email protected] 8 points 1 year ago (1 children)

Because your store probably doesn't serve thousands of people to validate the cost of the infrastructure. My city has busses, but it also has corn fields and open lots and a lot of spread. It's just not viable to walk all your groceries a mile to and from the bus stop both ways for a bus that comes every hour. It's different when every train and bus is full and the need is well met.

Ask for more taxes and more spending on this infrastructure, or use your car.

[–] [email protected] 10 points 1 year ago (4 children)

The infrastructure is developed around cars so obviously using cars makes sense. We could have smaller grocery stores and have it closer to neighborhoods so people can walk to it but we have buses which only come once an hour which takes 30 minutes to drive 2 miles and your grocery trip will take 3 hours so you are better off just buying a car!

Oh pish posh. China is exactly as big as the US and you can get pretty much everywhere for a few bucks in high speed trains.

Trains are fantastic and the US should definitely be investing in them, it's a huge disadvantage and a national embarrassment that we don't have affordable and effective mass transportation.

[–] [email protected] 19 points 1 year ago (1 children)

China does a lot of stupid things, but their train network is admirable.

isn't that exactly what trains were designed for and are best at?

[–] [email protected] 7 points 1 year ago

You are correct. I can only assume that person got trains and trams mixed up.

Trains famously bad at traveling long distances.

[–] [email protected] 16 points 1 year ago (1 children)

No, trains famously bad at “last mile” travel, except that in America it can be “last dozen miles” between a city big enough to have a station, and the place the person is going.

[–] [email protected] 13 points 1 year ago (4 children)

This is again a problem of America not investing in its transportation infrastructure, not a fault of trains.

Trains have their bigger advantages on long distances. You get tired in a car, you can't go pp or take a nap. Your costs rises proportionally with the distance etc.

[–] [email protected] 11 points 1 year ago (2 children)

Just north of the us is a mainly freight railway system that spans the width of the continent...

Then there is this image in an article about that on Wikipedia The spread out reasoning just seems silly to me on the basis of that literally being what trains were even for in the first place, going distances not suitable for horses. If it connects cities, that is also a start that shouldn't be passed on for being imperfect.

The only reason a car would be needed at all in north America is because of all the poorly designed car centric infrastructure that ends up not even being good for cars as demonstrated by the absolutely heinous traffic that only seems to get worse with every road "upgrade" I have ever seen the before and after of.

There are tons of areas of the US that have the population density to support it, but still have horrible train service. We made deliberate decisions to favor highways over trains, and we can undo those decisions.

Why would highways be less susceptible to the "spread out" effect than trains?

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.

[–] [email protected] 9 points 1 year ago

I thought the same thing!

[–] [email protected] 7 points 1 year ago* (last edited 1 year ago) (3 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.

[–] [email protected] 17 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.

[–] [email protected] 11 points 1 year ago (8 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.

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.

[–] [email protected] 22 points 1 year ago (2 children)

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

[–] [email protected] 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.

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

Financially or electrically?

Kinda like F-Zero?

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

[–] [email protected] 11 points 1 year ago

Wirelessly?

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.

[–] [email protected] 12 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.

[–] [email protected] 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.
