How Cool a Wireless Charger Can Become in the Future

When the battery runs out, it’s nerve-racking, but unfortunately, it happens. The more functions our devices provide, the more power they need, and they’re hungrier than hungry hippos at this point! That’s why charging technology is all the rage now, and the new big thing is wireless charging.

Even though we’re just now seeing this technology take off, the basics of how it works were discovered not long after we started to understand what electricity is. Near the end of the 19th century, engineering mastermind Nikola Tesla showed that two powerful magnetic fields can slightly transfer energy between their sources when they interfere with each other. This trick found its use more than a hundred years later!

SUMMARY:
- Every object with enough power is a potential source of an electromagnetic field.
- Magnetism and electricity are two sides of one coin. When electricity flows, it creates an electromagnetic field.
- To make a strong electromagnetic field with copper wire, you need a lot of it. Still, it’s one of the most fitting materials.
- The biggest surprise here is that the technology behind wireless charging hasn’t drastically changed since Tesla.
- The main problem engineers struggled with for a long time is that coils weren’t effective. The power of the field depends on the number of coils you can fit in the device.
- Another problem is that electromagnetic fields need to be close to each other to keep a strong connection.
- That’s why wireless chargers today come in the form of mats – you need to put your phone right on it to get any juice at all.
- This new tech isn't huge yet because let’s face it – wires are still faster than an electromagnetic field.
- Wireless charging takes around double the time to charge a smartphone from 0% to 100%.
- There’s no way a short-range electromagnetic field can cause any harm to you.
- As you can imagine, the whole method of electromagnetic charging won’t stay the same. As with anything, it’ll only get better in the upcoming years.
- Resonance charging will be good for devices with a high level of power usage, like cars, laptops, or even some robots.
- Another idea researchers are considering is laser charging. It may be extremely powerful and focused, but it has big bugs to work out first.
- A laser will work on any distance but needs a clear line of sight to the device. If interrupted, it won't work at all.
- Some other fresh research is aimed at the use of infrared light-waves, radio signals, or even ultrasound waves to charge phones and other devices.

If you could charge your phone with sound, what sound would you choose? :)

Bright Side: copper is an unbeatable conductor of electricity





Also Bright Side in another video (why graphene will take over the world): graphene carries electricity more quickly, more precisely, and more efficiently than any other known material.

Bright Side can never stop uploading videos

We just need to figure out how to turn lies into energy; politicians will finally be able to do something good for society providing free and unlimited energy!

I would like this type of charging on my bed cause i spend a lot of time on my bed.

[rashidjahanzeb]

Who is disliking this type of informative and interesting video & why?! 🤷‍♂️

[CanonicallyAThief]

I've always wondered how this works thanks

[HTVcricket_]

how do you animate videos like this? what is the software

[twinsisterfoodcountry]

Nice video i love's your vedeos so much ❤❤❤❤❤😊😊😊🙂🙂🙂🙂

[kerylorbsmultidimensional]

Yes this Wireless technology used to be commonplace before the last reset

[adrygopi]

Hey Bright Side, can you make a video about why we need to “catch our breath” after physical exertion. You’ll probably never see this but if you do, I like your videos.

[infinityacceptance]

Your linguistics skills is fabulus. I like it

[marnie]

Thanks bright side for teaching me this!

[jayme]

I just got my phone out of a wireless charger when your video popped up

[Edward_Gonzalez_]

Me watching this after I bought a wireless charger and want to see how it works 😆

[thegamingkangaroo]

Fun fact that i generated:
Putting your devices volume loud for long periods of time you'd probably lose more battery

[Quran-li]

Thank you aloot!! 🙏
It was such a nice video.. Increased my information.. Liked it aloot👌💕

[belalcharmand]

You forgot to mention portable wireless charging, I have a charged power bank that charges wirelessly, as opposed to carrying a cord with me when I’m not home. $29 from Kmart, not bad!

[carolynmiller]

I literally only use a wireless charger cuz my charging port is kinda broken and I always have to wiggle the charger around to get it to work. Wireless charging is way better and faster for me.

👍👍👍The more modern, the more has high quality of using, thank you for your sharing.
