kirby march Barcena : It took almost a century for Tesla's dream of wireless technology to be adapted. Too bad he died as a poor scientist despite trying to invent something for the people's benefits without financial gain.

Killer7481 : USB-C is so incredibly fast that unless wireless charging is somehow insanely efficient, i don't see the point. for those who are not in the know, my nexus 6p can charge from ~30%->100% in less than 1 hour.

Chris : Props guys, I'm an EE student at a renowned University and we are working on the topic covered here (we're doing a bit better then DOE currently). I am completely surprised at the accuracy of the info here and thank you for informing people.

Zane H : I hate the way you had iPhone as the example on your display, Samsung had Wireless charging phones years BEFORE Apple implemented it, give them the credit not Apple.

Ricky : Wanna hear a joke? Yeah..me too

coolal19 : Based on the title, I honestly thought this video was going to explore the ramifications of generating localized electromagnetic field distortions and their potential negative effects on the health of the human body.

SteveAkaGoatpile : cables are efficient. and no matter what, if you have money, space and energy for conductive charger stations for anything, you can instead to it easier, simpler and more efficiency with just plugging in a cable. chargers in tables? how about simple sockets in tables? chargers on parking spaces? how about a sockethub? seriously, I just don't see this ever becoming popular.

REA987 : Logic is simple; any mobile device (smartphone, tablet, laptop, music player, e-book) can still be used and charged at the same time while it was plugged to a power source. On the other hand, devices cannot be used effectively while being charged wirelessly since you cannot detache them unless you are okay with charging disruption. Just get a longer cable which can be extended and shortened.

Sean Ferney : power problems? nuclear power is really the only good long tern solution! A awesome design is the LFTR or light liquid florid thorium reactor. its solves or mitigates all the problems with normal uranium light water reactors. seriously just look it up LFTR technology, you wont be disappointed!

Von Neely : I'm curious as to how Apple is going make sure their wireless chargers are incompatible with anyone else's.

Anodyne Melody : What would happen if someone with an internal cardiac pacemaker implant were to walk over a section of street which had an inductive wireless charging circuit below the pavement in a parking spot meant for electric vehicles like the one shown in the video? Would it just charge up the battery inside the pacemaker? Or, would it overload the circuits in the pacemaker and kill the pedestrian? Thanks for another great video Real Engineering!

Douglas : What do you prefer: slim phone or 1 week battery? With less than 5mm you can have 1 week worth of battery. Plug the phone to the wall would not be such a problem anymore.

Bomberman : Did he say "Tesla Model 3" and show a Tesla Model S? *TESLA FANBOYS TRIGGERED*

Dialgavspalkia : The truth is: They aren't really "wireless" as they have to plugged on the wall in order for them to work, which requires a cable!

whoeveriam0iam14222 : wireless phone charging seems pretty useless to me. you either plug in your phone or you plug in the pad and your phone can slide off that the problem with electric cars is that if you're not rich enough to have your own parking spot you can't charge your car at home

Aaron Urias : I can only see a few practical uses for wireless charging (as it is now). At a Cafe, just need to give it a bit of a charge while you sip your drink, or when when you go to bed and place it on the pad while you sleep. That's really it, wireless charging while you drive sounds pretty cool. Until we have actual wireless charging with a range of at least 6 feet, Wich I'm not sure if that's possible, this technology will not grow passed those two

Mohamed Mokrane : When I click the bell 🛎 icon for this channel, it says Error 404

DragonTechRoyale4k : I love wireless charging!!! It’s so much better than wired charging (even fast charging)!!!

RePlayed TV : 3 words. GENIOUS NIKOLA TESLA

Jay Perrin : This affects 'current' technology ;)

Nemo D333 : wireless charging is for silly people who like to waste their money on useless things. First of all all these new nick-nags uses devices energy to monitor state of the battery, devices activity, time of charging and so on. It drains battery 24/7. Means you need to charge more often. By switching off all that crap, gadget runs all day+ with out problems.

Cupcake hero : Wireless chargimg seems like a great theory but in prictical use it takes almost twice as long with it enabled But for the wireless cars i was wondering if they could not use heat energy generated by the sun+the heat from the asphalt cause the get really hot can someone tell if thats a good alternate power source plz

sicunder kahn : Even 10% waste of energy is a big damage to the environment. I never liked wireless charging because of the inefficiency.

skepticbb93 : Any health issues if wireless charging pops up everywhere? Combined with wifi signals, cellular radios and whatever else is bombarding our bodies and brains?

24Hour Of Alonso : Reasons I watch his videos: 1. Accent 2. Accent 3. Accent 4. Interesting content 5. Accent

Dimitri Sanchez : It's funny how we are jumping into a "wireless" future without even considering the health consequences. I truly believe that this post 2000 generations will have the highest rates of cell abnormalities ever in human history.

dil The pickle : I’ve seen stores with charging stations, but usually no one uses them out of fear of loosing their phones.

George D : I think that being able to wirelessly charge my phone is simply amazing, and I have gotten so used to it that the lack of it would be a deal breaker for future phones I would consider. Firstly, I am not a heavy user and my phone (a nearly two-year-old S7 Edge) regularly lasts me around 70 hours between charges. I have a wireless charger integrated in my bedside lamp, so I just put it down before I go to sleep and then simply pick it up in the morning, no hassle at all - no wires, plugging and unplugging from the wall. I honestly don't even know where my standard charger is right now, I haven't used it in a long time.

iRx Destiny : we need fusion energy, and then all the energy problem will be fixed

Kakunapod : Coming from an EE, autonomous inductive charging is simply a stupid idea. Why? Why can there not be a physical connection that is automatically made between physical contacts? Yes it adds mechanical parts to the car that could wear, but the mechanism does not have to be complex, and it would achieve the same level of convenience while CHARGING THE CAR FASTER.

oakmen : Real Engineering ha, what about the benefits? Of course you loose energy compared to a cable, however your phone will hopefully last longer removing another point of failure. Produce less phones? No that's not going to happen. Incremental performance really is not as it once was. People are still rockin' phones from 5+ years ago. That is what we need. Yes, I am a fan of wireless charging and even better, there is a STANDARD for it. The battle was won by Qi years ago and Im glad they did.

ganesh jadhav : Why this is called wireless...? Pls make video on liquid cooling in smartphone

Simon : I doubt this is going to make an impact for phones. Cars, Laptops, PC's,... Stuff you have to place down to work on or leave stationary for a while. That is what this technology is good for. Increasing the range will inevitably reduce efficiency. A charger for a car that detects when you're in park mode and raises closer to the receiver would be cool though. I hope Tesla and other manufacturers are working on something like that.

Callan Whitney : I think a smarter approach given the current (haha) inefficiency of inductive tech, is that we might instead find power inputs on the underside of cars, and chargers that come up from the floor that can work in conjunction with the car's intelligence and find it's way to dock completely unassisted by humans. We can use the tech that's already in Tesla's now to our advantage and make markings around the parking space on the ground that allow the car to see exactly where it is, and then the charger can come out of a hatch from the ground up and plug in! Easy 100% efficiency, and I would say we're much closer to achieving this than slowly developing convenient inductive charging with 90% or higher efficiency over decades.

Bob Is The Builder : Great video. I liked the fact you broke the technology down so the average person can understand it.

kwokshsee : "Churging"

Sam Host : Is wireless technology good for health?

Layback Studios : 0:20 but mine lasts for several days at a time with light usage #4100mAh!!!!!

nikoladd : Charging a 2Wh phone at 40% efficiency is somewhat wasteful, but charging 50kWh cars at 40% efficiency is extremely wasteful. No grid in any country can handle that as of now.

John Macintosh : Is the truth that it is less efficient? Cost efficient/time efficient?

Hector Diaz : I'm still confused as to how this witchcraft works.

M4 Thirsty : why does the added impact of wireless charging even matter? If we didnt have it, people would use normal charging and still have the same impact :? correct me if im wrong :P

varjagen : what is the music 0:40 seconds in?

Kadoc : I wonder if the earth sometimes makes fun of the moon for having no life?

Poker Snob : Why the first 73 people....lol Seems odd?

TecSanento : Please consider electric toothbrushes as well - they are already using induktiv charging in mass production

Menstrel : I do not want these devices anywhere near me.

Aria Dhika Rayendra : I'll just stay at wired charging for now, I don't want my electricity bill to be high

Daan Sloots : love your channel because i always learn something and love your voice. gods blessing and pls stay awsome
