#wirelesscharging #Electreon #EV

Hi Thanks to the many viewers who've sent this one into me, we've got Wireless Electric Road charging and this is nothing new. People have been companies have been developing these for many years now and I've even said in uh, some previous videos that yeah, this technology works but no, it's not going to be viable on a mass scale to build into Uh roads on like a mass scale and everyone's going to have a wireless electric car. We can have much smaller battery packs and your car will as you drive around, it'll recharge itself. And yeah, technically it's possible.

but just like solar roads, yeah n it's not going to work. So AP News here: New technology installed beneath Detroit Street Can charge electric vehicles as they drive. They've installed what's built as the nation's first wireless charging public roadway for electric vehicles beneath the street just west of downtown. Detroit Detroit We'll look on the map in a minute.

Copper inductive charging coils allow vehicles equipped with receivers to charge up the batteries while driving idling or parking above the Quart Uh coils. So they've installed a quartermile segment on 4land Street. We used to perfect the technology ahead of making it available to the public within a few years according to the M Michigan Department of Transportation And there's actually a lot of funding behind this from the US Department of Transport the dot redefining Green Transportation New Federal Bill Boosts Wireless EV Charging Programs The new Law Uh would create a dedicated grant program US Department of Transportation Uh funding for Wireless EV Charger projects. This includes $250 million in Grants for wireless EV charging initiatives such as roads, parking lots, bus routes, airports as well as Coastal and Inland ports.

The wiress EV charging bill is rooted in the Michigan Department of transportations M do pilot program uh, that pioneering project blah blah. So have they already spent $ 250 million? or it's available or whatever, But that's a lot of coin. So anyway, here's the street here. Unfortunately, there's no Cometry but uh, there you go.

It's there's a charger box over there. they've got a van which is equipped with this Crews have been stalls build is the nation's first Wireless charge in public roadway. a street oh people are going to cross, don't hit them I'm Ellie the EV the road charges while me charges me while I drive in November of 2021 Governor Whitmer Announced an exciting new Initiative for the first public electrified roadway in North America And today we are here to celebrate this. this big and important celebration I'm Electrion are really celebrating milk in that $250 million cash cow.

They didn't get all of that admittedly look. So there's the robust con revolutionary it'll be revolutionary for for electrifying and really being able to get the benefit. Uh, to the max. Well, you want the benefit to the max.

You don't want a half ass benefit. You want benefit to the max. We're going to use this as a springboard to learn and understand how things work. Fair enough, but ultimately, how can we scale this up? How can this eventually be something that we use across the state of Michigan And the United States No, sorry dude.
like I Like I fully support like testing this sort of stuff. but you don't have to test it on like complete strips of road. So here's the actual uh coil that they got installed from this Electrion uh company. There are other companies that make these wireless charging solutions.

they aren't the only Uh one. And yes, they do work. Yes, they're going to have quite a few Niche applications I think in various uh Niche locations, but installing them everywhere on all the roads? Yeah, no, it's not going to be practical for a multitude of reasons you can probably already. Yes, So we look at their website in a minute.

They do claim they're easy to install and they can install up to like a mile or something in one night or something like that. They're going to have these automated machines that dig up the uh, ash vault and they, you know, just lay them down and you know, recover it on top. Bob's your uncle? Okay, it's going to be EAS a lot easier than solar roadways I think but still not quite there cuz look I mean this is a concrete base with the Ashev on top, right? and what's this? slot over here? You got to cut a slot in the middle of the road for the for the cables I Don't know. Maybe it's not as bad as it looks there.

So anyway, if you know the exact details on that, leave it in the comments down below. But yeah, it's it. It's easier than solar roadways. There's the money shot on the connector there.

So anyway, there's lots of other articles on it. There you go. They've got the control box over here, so I'd be curious to know if there's any like Electronics installed in this box underground. cuz if so, that's going to lead to reliability, uh, issues for example.

And yeah, or whether or not it's all in the that control box over there. And then you've got the copper losses running over cuz remember, these are quite High powerered things. So you get going to get sub substantial copper losses just in the conduction. um, over to the coil itself.

not to mention the efficiency in the coil cuz these are resonant coil converters. We'll have a look at the technical details in a minute. I Got some uh, great info on that actually range, availability and charging infrastructure and speed to charge alongside affordability. Some of the biggest hurdles for American to purchase E vs.

Those challenges are resulted in the increasing pace of EV sales slowing this year. Yeah, I Heard they did actually slow this year up inflation. Automakers as a result, have delayed EV launches, postponed production dates, and yeah, so they're trying to, Of course the bulk fast bulk of the cost of EVS is in the battery pack and that's not really coming down anytime soon. And no, don't bet on a revolutionary order of magnitude decreas in cost, order of magnitude, increase in battery efficiency.
It's just not going to happen. So I Guess what they're proposing with these Wireless Road systems is like a halfast approach to minimum or trying to trade off the size of the battery pack required. Of course, you got to have some battery pack in there, otherwise you can't drive on non-electric uh roads, uh or but you know you don't want it so big that you get your I'm talking Yankee miles here. You know you don't want your 300 or 500 mile range or something like that, but you don't want it so small that you can only get like 10 mil range when you're like off the electrified roads and and stuff like that.

So it's going to be this like they're trying to do this half ass tradeoff between minimizing the cost and and then electrif putting the cost into electrifying the roads so that the cost of the EVS uh can come down and and and convenience as well. So you know a lot of people can't charge at home. simply don't buy an EV if you can't charge it at home. Pro tip And you've got the charging infrastructure of course, the fast charging whether or not uh, regular petrol or gas for you Yanks uh gas stations will have like EV charges, they're always full or they're always broken down.

um and they take longer to charge than filling up your regular uh petrol tank here in Australia or gas tank uh which takes like you know, a couple of minutes I've timed it once drove into the petrol station, got out, filled it up, went and paid, and got out of there in like 2 minutes or something. like so quick. Anyway, so that's all a big tradeoff there and that reminds me of a fellow YouTuber who did a video uh calling electric buses a scam and then when after I did a uh rebuttal, uh video to that cuz I've done a video on uh visiting an electric bus Depot and take a look at electric buses I'll link that in down below and they're quite viable and yes, an update on that. They are like they've expanded their Fleet and it's working great and they've invited me back and everything anyway in a followup uh video I Had to admit oh yeah, electric buses are viable but you know it's better if you have like a much smaller battery pack in there and you have mostly overhead trolley, install all the overhead wires on all the uh streets and then you have like this half ass solution of you know H you know mostly trolley wire overhead use but then if you have to go off the routes and stuff, then uh yeah, you can use your battery pack.

So and they're trying to do the same thing here with electric cars on a consumer? you know Mass consumer? uh, street level scale And yeah, it's going to be the same Half and half. Uh. Pizza Faure? No, no pineapple either. And there's an older article here from 2021 here.
Um, once again, Electrion Wireless EV Charging Pioneer Electrion receives you a approval un approval to integrate its technology with all vehicles and transport passengers while charging wirelessly. Uh yeah, really. Um, see. Here's one of the major problems is that you've got a private company here.

in fact, but they're not the only one. There are multiple private companies try vying for trying to get the lucrative Cash Cow Um, you know, 250 million Buck a piece of the pie? That's just that's just the starter, that's just the app aiser. um of you know, electrifying all of these roads. And so you've got a private company technology that you have to build into your uh, public infrastructure.

What happens when that company goes tits up? What happens in to the systems and they come a Guta No good anymore. They break down, They don't work, they can't be maintained, All your uh investment is just useless. CU You've bet the farm on this one company. Where are the standards? Where's the open source in W? N Yeah n Oh, it's an editor picking Forbes Wireless Electric charging.

They may be advancing. Um, yeah, they're going to advance and then they'll just spin off into a tiny little niche and they'll never be used. You will never see these on your public roads. Anyway, let's take a look at where they are going to install this.

So this is: Detroit Okay, this is downtown Detroit here. I've never been to Detroit but hi to all my viewers in Uh Detroit In fact, if if you're in Detroit take a visit to uh, the 14th uh Street here. uh between Dowel and Maranet Street If I'm pronouncing that correctly, they've got a strip here of uh Road and they've electrified this and well, the first thing to look at is okay. they've done this section of Road Okay, it's a test system.

look I Fully support testing this sort of stuff. but I Don't think you need to test it on like large, uh, like strips of road because it's never really going to be used on large strips. Road This sort of technology is more ideal for something like a taxi rank. For example, you could have EV uh, taxis instead of charging them up, they you know they're sitting at the taxi rank for a certain amount of time.

You could have like a a short strip of Taxi rank. But to have these things like just as people drive over them like yeah, they want to install them on Main routes first and then minor routes and like. But it's just going to be this half ass tradeoff that nobody is going to want to be caught short. It's the chicken and egg thing, right? If you're buying an EV you don't want to like until they've installed and electrified all these roads.

No, you want that big ass battery pack. You want that 300 mile range or whatever it is, right? You don't want the 30 mile range Jobby. And then you're caught caught short every single day because you had to take an alternative uh, route where there's no. Even if they've got some infrastructure and all the major roads, you know if there's traffic accident, you got to go off and you're stuck in peak hour traffic and you're you're only at your 30 mile range.
your EV you're going to come a Guta So yeah, it's just imagine trying to Electrify All of you know, like, even a substantial number of of of roads to make it, uh, practical for people to make the decision to buy a lower uh battery pack and for the manufacturers to produce a lower battery pack uh, car using proprietary technology from, you know, some third party company that might go tits up it. It's just it's never going to happen. It's Fantasy Land Not withstanding Mr Melon's input. The next question for us is where to build our Factory How about fantasy land? Anyway, here it is.

they want to install it on this. Well, they have installed it on this uh strip here and and you can see this uh building here in uh some of the videos and and stuff. So this is the street they've been stored along perfectly fine as a as a test. uh thing.

but no I would rather see this like like go For Broke right? tea up with a taxi company for example, are there any EV taxi companies in Detroit or any other city in the US right? And and like fund them to install these uh systems on their existing EVs and see if they can. you know and then install it in like just a strip in like a EV You know, like a taxi rank at an airport that's you know, highly used something like that and just but like just a strip of Road here. What does it do when you've got one van that you've equipped and like it's not showing you any practical system scenario? You can show him that the technology works and the technology does work. It's a resonant coil system.

It's all proven technology. It absolutely does work. You know there's questions about the efficiency and stuff like that, but um, and and you know and when you drive over to speed and stuff like that? oh look, they got some higher bikes here. Are they trick bikes I can't I I can't make that out.

Leave it in the comments down below. Anyway, there you go. So yeah, they've installed it on this strip here. and yeah, good on them.

They have, you know, a 250 million Yankee bucks. Um, pilot program. not just for this strip, but that's like a whole whole you know all sorts of people are milking that cash cow, let me tell you. But so right off the bat, you've got problems with the chicken and egg solution obviously.

Uh, and that manufacturers have to sell the lower Uh price cars with the smaller battery packs. but will people buy them without they having an extensive network of uh, these systems already installed. And then the second problem is tie in your public infrastructure and the auto and the automotive manufacturers uh to tie these things in to a private company who like controls the Uh technology for all this sort of stuff. and I don't think they're going to be interoperable.
So if if the government or local Council pay to install the this infrastructure in the Uh roads can like, if that company goes bus, can another company start using like it's just yeah n And then you've got the efficiency of a resonant charging system like this. Especially when you're driving over it and you're not just sitting there. These things can be. You know you can live with the Uh efficiency losses in these resident coil systems.

They're actually quite reasonable, but uh, in a stationary thing. But when you're driving over them and they're switching off and on really quickly, you got problems there. Then you've got problems with the uh electromagnetic radiation as well. because what? How like these things are really high power resonant coil systems.

And sure, they're resonant coil. Sure most of the energies going go into the coil in top of the car. but uh, then you've got like all the other electronics in the car and the people as well and their devices that they have uh in the car. If you got this massive amount of electromagnetic energy, sure they can, you know they got Safety Systems to switch off and all that sort of stuff.

But like yeah, you know that there's potential problems there too. And then you've got the reliability of the electronics that go into all this. Like I said, if there's electronics in the road there, that could be Troublesome you've got Electronics in the box there. If you're an EV owner like I am.

um, you know you might be used to like turning up to an EV charger that's nonfunctional for example for various reasons. and yeah, I don't think these systems are going to be any more reliable than your like roadside, uh, you know, or your fast charging uh, networks. So anyway, let's have a look at the Electrion. We're on their web page here.

Wireless charging. Oh, they got the bus there. Yeah, good luck with that I've done I've visited Electric Bus Depot and sure this is a way you know the bus comes in at night after it's you know daily thing and it could just, uh, drive on top of the charging pad right? You might think that's great, but I've actually been on this an electric bus and I've actually plugged. I' driven it.

not me, but I was sitting there while they're driving into the Depot and then I just plug the thing in. it takes like I don't know 10 20 seconds to plug the thing in. it's pretty easy and then you get the utmost in Energy Efficiency in transfer. In terms of speed and you don't want to piss energy away, do you? That's bad for the environment so you to just plug it in.

you don't need a wireless charging pad, but as I said, there could be Niche applications. you know the the classic one I think of would be like a taxi rank at an airport for example. Anyway, let's play this video shall we? Electreon and its unique technology developed in order to change the future of Transportation The change starts today. Electrion Smart Road Quickly and efficiently transforms our public infrastructure into a source of Advanced Energy public Transportation Vehicles will not require any refueling or charging at any time whatsoever.
So what does Electri? Char Electric vehicles will receive continuous power while the vehicle is being driven directly from the infrastructure embedded under the asph road inad of carrying the heavy and expensive battery. With a limited driving range and a short Lifetime With Electrion groundbreaking technology, one can simply travel non-stop non-stop Our City's landscape will change dramatically dramatically. No more gas stations nor cumbersome battery charging station. More gas.

St No More battery charging station. Number of vehicles traveling on the Smart Road increases air pollution around us will decrease drastically. Dr Elon's Innovative and sophisticated technology is extremely efficient and very affordable. The upgrading of a mile of an asphalt road will only require the embedding of a narrow copper coil which will be connected to the electricity grid.

and that's it. We completed another Smart and Green Road in just a few days. The updating of vehicles is also very simple. We install a receiver at the bottom of the vehicle and we are ready to go.

I'm sorry, but you know there's so many different types of EVS out there. you're not just going to whack this on the bottom of an EV. It needs like it needs bolt in points and then it needs compatibility with the EV. In some way, how do you get the wiring infrastructure into the car? It's not as easy as just going.

Oh, we've got just a universal solution. You just put it under there. Boom, you just driving your EV and 10 minutes later they've installed it. It's complete.

Not of no, there's no way that is possible. Electron's plan is underway. We are moving fast on the road to Turning entire cities into electric and green cities. After we successfully complete the demos, we are embarking on pilot projects all over the world.

Together with our International Partners we shall start electrifying main routes for public transportation. The next stage will enable us to continue the upgrading of the main roads of cities and from there we shall open and service distribution Vehicles sharing vehicles and finally autonomous vehicles in order to ensure maximum flexibility. The vehicles will also be able to travel on non-electrified routes. Yeah, once again, it's tration is already here.

The technology exists and works successfully, changing the reality as we know it. You are invited to join us and follow the pilots and the first deployment on Electron's website. We will. We will follow this on the Eev blog here to see in 5 years time.
I bet you I bet you I'm coming back and nothing's happened. Nothing at all has happened because people realize there just the chicken and egg problem alone. Nobody's going to buy a small ass. EV You can't just retrofit it like it like it's nothing to an EV there's going.

There's going to be all sorts of you can't just install it under any EV Willy-nilly it's just. it's just not going to happen. It's not going to happen anyway. I'll link in to this if you want a Fa analysis of Wireless EVS This is just a failure analysis.

Okay, failure modes and effects analysis of wireless and extreme fast charging. And this is from the US Department of Transportation themselves, the ones who are funding the 250 million Buck pilot program for testing these things. So I'll I'll link it in here and this is incredible. Wow.

I Like I Cannot go through all of this I Am sorry here. Here is how it's typically going to work. This is not specific to this particular manufacturer. One, this is just more uh in general.

And you've got the two resonant coils here. you got a compensation network uh, inside the car. Here you got the power. Electronics But yeah, how do you integrate the the output of this into the Ed Just run a cable up and bodge it in to the to the existing like in um charge Outlet on the side of the EV What do you like? Come on.

and if you think the automotive manufacturers are going to build a proprietary system like this into their uh car, then I've got a bridge to sell you links. Australia and New Zealand It's the classic. XK CD How standards proliferate. There are 14 competing standards.

14. Ridiculous. We need to develop the universal standard that covers everyone's use case. Yeah, situation.

There are now 15 competing standards. It's exactly what's going to happen here. Yeah, so I'm wondering what if any compensation Network and Power Electronics is embedded under the road there and how much of it is in that like Grid in face box over there? Don't know. and I'm sure there's lots of comp because you have to add a ton of safety and automated features to this as well.

so it's going to be like a highly complicated uh type thing, but sure it's it's possible. And these are relatively easy to install because like bread and butter stuff for road infrastructure is installing the sensors. The embedded coil sensors for the Uh traffic lights. When you drive up to the traffic light, it detects that there's a car there.

It's got a coil in there that detects your you know, the metal in your car as you drive over the thing. and these are embedded like in practically every automated traffic light. So it's a similar sort of thing here. So it's not on the scale of solar roadways.

So yeah, I I Don't doubt that they can store these relatively simply, but just on the mass scale of all the roads. Yeah, know. Then they got the differ uh compensation techniques LCC series compensation and LCC LCC compensation and this is just great. So I'll link this down below.
and yeah, nerd nerd out. power factor correction topologies and like. They go down to the Circuit level and then wireless charging pads and like different topologies and things like that. Now here's are the health and safety thing due to F due to failure to control EMF emissions Now I'm sure this Uh technology has lots of safety built in, and if it's not absolutely you, it shuts off absolutely instantly the second that you know the coil is not resonating with it and all that sort of jazz.

But then how much are you exposed to? How much is your other electronics in your car? exposed to? how much is other personal electronics you've got in your car, uh, exposed to? Anyway, so they' got flux density in micro Teslas over here versus the general public exposure limit and the occupational exposure limit versus frequency I Think these operate about 80 khz. Um I haven't double checked that something like that. So they go to the air gap stuff and the regions of uh, you know, the magnetic fields and and they go into everything. look, direction of flux, un, unipolar receiver and transmitter.

It's it's it. It's terrific stuff, but just be aware that there are safety and other interference. Uh, you know EMC Emi Uh, you know interference. uh, problems because you don't want to like how much Electronics hundreds of microcontrollers inside the modern, uh, automobile.

It's just nuts. So here's the various Uh standards. that's all to do with, uh, all this sort of jazz, right? But the interesting thing, like they got all these subsystem components and theyve got FMEA analysis and stuff like that for you know, things likely uh to occur with all this, and light duty, static, wireless, charging, and all the subsystems. This is just.

this is nuts and they just got more and more. and more and more. This is incredible. Thank you Department of Transportation That's where some of your 250 million bucks is gone.

I'm sure they even go into core selection and I Oh anyway, this is nuts. But anyway, the interesting thing here are their worksheets here. Okay, and these are causes of faure modes. Okay, so they got all the fure mode con.

Like the likelihood of all these different faure modes for all these different systems. The fure mode consequences. Okay, I just wanted to show you this right that this is just like the common mode choke, right? So they' got this for the common mode choke. Okay, for the Y class capacitors inside this thing.

no reefers you don't want Reaper in your roads although it might smell nice shielding for the Emi filters and they've really gone to town on like filter capacitors, the rectifier modules, the DC link capacitors, the heat sinks, the Boost inductors, the Igbt power modules, and these are all of the likelihood of all these system component fires. Sure, you're going to get the same sort of thing in your, uh, like, roadside Fast charger for example. That's why a lot of these are out of, uh, out of commission or all the time. It's not just vandalism, they always seem to have something wrong with them, right? And there's all sorts of.
They're complicated beasts. And these wireless charging systems are no different really. And then what happens? You got to fails. You got to dig up the road now.

Okay, great. but sure enough, a lot of this might apply to the Box on the side of the road. and they might be. And then you've got the couplers and then you've got the litzwire in the receiver pad for an object detection systeman because yeah, you got to detect.

You know, people walking over the thing. you know you don't want to go over it with your steel cap boots and it it turns on wireless communication networks and then the mosfets as well the cooling units. The comp I just wanted to show you this. they've gone to town.

you know they make this look all you know willly. Wonka Chocolate Factory You know Oompa Loompa land. Kind of fantastic technology, but yeah, like you want to install these on every single Road You want to dig up and install this a long strip of every single Road It's just not practical. yeah n this is.

this is just not going to happen on any Mass scale anywhere. Um I can see it being a niche. uh thing. Totally okay.

if you want to retrofit your Fleet of taxis or maybe your Fleet of the delivery trucks or you know something like that Amazon might you know? because Amazon have ordered a whole bunch of uh EV trucks, haven't they? Maybe you could retrofit uh those. but even then like they don't stop it spe they just go to random houses everywhere so it's absolutely no use. So really, it's only back of Base but then you can just plug it in and plug in is going to always be superior. um to the efficiency and charge rates of any resonant wireless system like this.

and buses like I've been on electric buses I've looked at their infrastructure and it it it works. It's fine, and yeah, maybe at a few bus stops somewhere you could supplement and possibly that is certainly possible. but to have these on consumer cars and like, we're going to lay down all these strips of motor in every lane every like, maybe you have a special EV charging Lane if you got an EV you can be oh look I'm special I'm in my EV screw you you polluting bastard. but that's just going to cause resentment on the road and it's going to increase traffic congestion and it's just no, no, it's not going to work and then you have the manufacturers of the cars.

they're not going to make smaller, they're trying to make bigger battery packs cuz that's what the people want. Um, because range anxiety is is a real thing for new uh EV owners I've got an EV but I charge mine at home from excess solar so effectively I've got a solar powered EV It's almost 100% excess solar powered from my own residential uh solar panel system on my uh roof. But I've got the lifestyle to support that. But if you don't have the lifestyle that where you can you know, use and charge an EV and and in in a practical scenario, you're just they're just not suitable.
Just don't even think about buying one and trying to force it on people as some sort of green thing. Yeah, no, let's not get into that. But go ahead, leave it all in there. your thoughts and comments uh, down below.

but yeah, no. Wireless Um, electric car charging roads are not going to be a thing I Guarantee it. But hey, prove me wrong. If you think I'm wrong, leave it in the comments down below.

But yeah, now my official prediction is it's not going to be a thing. it's going to die in the ass and it'll have a few Niche uh. scenarios might be useful, but no anyway. catch you next time.

    It doesn’t matter if it works or not. Probably better if it didn’t work so they can rinse and repeat several times. These kinds of project make a select few people wealthy.

    If someone is lazy to plug the bus into charger, invent pantograph on top of it so it automatically connect to grid in garage. Groundbreaking.

    some pepole goes nuts when it comes to mobilephone towers. the output from one of those are nothing. compared to this.

    Imagine the amount of copper this would require. The price of copper is already crazy now days. And every time they have to work on a road (which is daily here in winter due to water main breaks) it's something they now have to worry about having to deal with. I really doubt this would also put more power into the vehicle than what it takes to drive over it, the magnetic field would also cause a bit of resistance. It would also wreck havoc with GPS receivers within the car or even people's phones so this would break lot of GPSes and such. My drone will complain about interference if I try to take off near an A/C unit. Imagine what these would do! I just see no use for this, it's more problems than it's worth. Better off putting that money towards putting chargers at every lamp post in designated parking areas. That would literally be cheaper, and more efficient than this.

  6. Avataaar/Circle Created with python_avatars @brainndamage says:

    A couple of things.
    1. Air gap will kill efficiency.
    2. Qi chargers have a coil on a big ferrite plate that's coupled to another coil inside the smartphone, the air gap is millimeters, but the ferrite also couples the magnetic field better. Are they going to rip up the entire road to install ferrite under it? I doubt it, so there you lose even more efficiency
    3. Eddy currents, if the road is built on top of reinforced concrete, the steel reinforcing bars will act like shorted turns and heat up, potentially causing arcs and destroying the concrete or even causing a fire, same goes for any metal pipes or existing electrical wires inside the road, do you want high current r.f. common mode coming into the electrical distribution wires and phone wires?
    4. Water in the earth and asphalt will absorb the r.f. and add losses
    5. Electrocution hazard, what if the insulation gets damaged and voltage leaks out into the road, it could electrocute anything that steps on it (this is potentially solvable by an earth leakage protection device built into the oscillator)
    6. Cutting up the asphalt to install the coils will damage the road and shorten its lifespan, especially in freezing weather, the cost of repaving the entire road and incident costs due to road closures and traffic jams will be far higher than any energy saved by the EV charging from said coils
    7. Transmitting high power r.f. into the open air will pollute the radio spectrum, at these power levels the entire thing will be like a radio transmitter that can propagate for very long distances

    Should we not just put magnets in a line under the car, with an electric linear rail in the road.
    Who need to charge a battery ?

  8. Avataaar/Circle Created with python_avatars @ralphj4012 says:

    Potentially, a relatively-low install cost in the UK, as we already have plenty of existing holes to put the coils in. This will sort the sit-down protestors.

  9. Avataaar/Circle Created with python_avatars @renevile says:

    i think it is only feasible at bus stops etc. where all it needs to deliver is equal to regenerative braking losses.

    Holy moly, it looks like Detroit first needs roads before taking this leap lol

  12. Avataaar/Circle Created with python_avatars @peterward2875 says:

    Strapping the receiver on the bottom of the vehicle sounds like a bad idea too; one overzealous speed bump, or a bad hit on a pothole and the coil in the car is taking damage. It's going to have to be integral to the car from the start, with enough physical protection to keep the road from breaking off that part (and still close enough to the pavement to receive the signal).

    Then once this is buried under the road, what does it do to the maintenance of the road next time it gets resurfaced; or when the water company needs to repair something under the road…

    Cool, btw The McLaren Speedtail comes with a wireless charging pad. Think it might be the only one,

    Living here, I can tell you right now, this will fail in 1 or 2 years. Our DOT (MDOT) is inept, and has been for 40+ years. They are all about "How much money can we get our hands on, and waste it". Our roads are sub-standard. A brand new section of freeway (I696 Between I-94 and I-75) took 2+ years to completely gut and replace. They had SEVERAL issues where they had to totally rip-out sections and put it back in because they did it wrong…MILLIONS in waste. THEN, after they completed it, they had to close it again to "fix" the road because it was SO UNEVEN that they had to run a road grinder down it to 'smooth out' the surface. There are already areas being cut-out and replaced because they are failing. Sub-standard materials, at premium material pricing….that's our MDOT at work….

    No, this stuff isn't going to work.

    It’s really a solved problem. It’s called the catenary. Putting it under the road surface is silly.

  19. Avataaar/Circle Created with python_avatars @absurdengineering says:

    Putting anything right beneath the street surface is a fool’s errand. It won’t last. The layers below the asphalt can barely stay put between repaying. Coils? lol. Maybe if they over-design the road as if it was a runway with blacktop on top for looks.

    I will not work in the UK as we have loads of potholes, however it would be a fairly good idea for use in a warehouse or something.

    But wait … solar freaking charging roadway that Heats and melt the snow at the same time and charges you, but wait order now and get the phone charger too…

    F Zero comes to mind. They just need to paint the road pink.

  23. Avataaar/Circle Created with python_avatars @inifin8 says:

    just put magnets on the road and install a coil in the car

    Sounds like an EMC nightmare at that dimension. Would love to do measurements

  25. Avataaar/Circle Created with python_avatars @wktodd says:

    It'd stop the road freezing 😉 even at 91% efficiency for it to deliver usable power, the loss in heat will be considerable

  26. Avataaar/Circle Created with python_avatars @cjay2 says:

    And when the batteries wear out, you still have the original problem. Just more BS to support their cash cow, and 'their' plans for OUR future. The rich, by the way, don't worry about these kind of things, ever.

  27. Avataaar/Circle Created with python_avatars @johnmorgan1629 says:

    Al a Helen Lovejoy – Oh won't somebody please think of the losses.

    Michigan government is absolutely FULL of wankers, this will fail like every other project and company in Michigan, is starting to do. Their leadership has no idea.

  29. Avataaar/Circle Created with python_avatars @jlev505 says:

    I’ll stick with my internal combustion and compression ignition engine vehicles. Don’t have to worry about anything. Just jump in and drive to anywhere I please without issue.

    When governments try forcing things on the citizens it usually has the opposite effect they desire. Look what happened with the “vaccine” 😂.

    I'm currently writing my bachelor thesis within the ELINA Project here in Germany. (Was also briefly shown on the electreon website). The goal of the project is to evaluate the feasibility of using wireless charging in public transport.
    The coils you can see in the photos are actually to coils per module. The black box in the slot are the resonace capacitors. Other than the cap and some temperature sensors there's nothing in the black box. Every pair of coil is individually connect to the Management Unit (MU) at the side of the road. Each MU can drive about 60 coils wich equals about 120 m (360 ft) of road. There is also a coil variant for static charging that is slightly bigger and more robust due to higher losses within the coil. We are currently evaluating if static wireless charging at bus stop is sufficient or if we still have to employ dynamic wireless charging too. The cost of installing these coils is still far higher than the cost of a couple additional busses but this is still in the testing phase. Currently the bus is only able to charge the energy needed for the distance traveled while charging making it effectively useless ( You would have to build it everywhere to make sense). The static wireless charging at the main bus stops looks a lot more promising. Once the Project is finished there will be extensive scientific reports about the cost efficiency and the general feasibility of such a project.
