This time, I will review the popular YouTube videos.

These days, even if it's good to watch on YouTube, sometimes people skip it or don't watch it if it's too long.

When you watch Youtube, do you scroll and read the comments first?

To save your busy time, why don't you check out the fun contents, summary, and empathy comments of popular YouTube videos first and watch YouTube?

Playtime Comments : [Veritasium] Electromagnetic Levitation Quadcopter

Je********:

2:38 CHEAT CODE: Up Left Down Right...there is no cheating allowed in science guys

UD*****************:

That outro 5:08 was the most 90s transition ive seen in a while

Pr*******:

Any suggestions on how I can animate the rotating circles the way it is shown at 3:35?

ra*********:

NY to Cali in 10 minutes. 4:20 They already have them in the underground tunnels they made with the megga tunnel boring machines.

Bi*************:

wowww that's so good, Can Anyone please tell me which software he has used for the simulation in 4:39s

Le*********:

Wow, 5:00 I must be living in the future, since I get from one city to another within a day regularly... cool.

Ph**********:

5:00 wow you heard it here first guise, in the future thanks to magnets we'll be able to go from one city to another in one day or less!

Ja*********:

Is there a way to absorb that heat and redirect it to produce energy?

NF*****:

What if you arranged the magnets like this:
↑↑↓↓←→←→B A

C0*****:

i only imagine razer loking at this and thinking


"man, that april fools prank was a good idea"

As**********:

I screwed around with this in middle school a bunch of guys and I thought it would be funny to sping magnets on a motor to use as a method of power transmission, never thought of using it this way even after learning about the moving a magnetic field thing in high school

Gr**********:

Imagine implementing this technology into beyblades

Ex************:

I want a antigravitationplatform without the copperplate, just flying over the ground like the uap's. ^^
No sound, no exhaust, no contrail or something.

Ky**:

So this is how the foundation makes 106's containment chamber.

Ki******:

Some day, I'll be able to go from one city to another in a single day... Gets on airplane

Ro*********:

Something tells me that some portions of this video are going to show up in future Thunderf00t videos.

To*******:

How would one go around calculating lift? What would one do to increase it? Stronger magnets? More RPM? Both? Is it possible to generate less lift on front side in order to "slide forward"?

4p******:

I first saw a similar demo at the science museum in Toronto when I was 12, with the same promises assumed, I'm 62 now.

0o***********:

what uses more energy, linear AC magnets or motors spinning permanent magnets?

mi********:

I cant help but think how this tech could be adapted to bobsledding, at lightning speeds! Copper track, with Tesla Sled, all iced up for hard contact turns.
Of course new designs for tracks...

Ge*******:

wonder if cats would sit on this like they do on Roomba's..?

Da****:

i had an idea for a levitating non-wheelchair using something similar. nice to see it would've actually worked :)

Me*:

My sister did this in the 80s lol...
In 4th grade as a science project...

Bi*********:

Woah. Imagine in the future when I can travel from one city to another city in one day!

RC*****:

oh yeah I can ride my bike with no handlebars.

Di*********:

It's called: "Flux,"...flux braking - reactance Chi X (Ohm's) + or inductance of z, impedance.

Ma*******:

Perfect...
Now we need to make all the copper roads
  LOL

Su*******:

I really would like to know how much energy is used to levitate since there that counter torque. and how much more efficient would that kind of transportation be compared to losses due to friction of e.g. ball bearings.

Ba************:

I was always wondering how them aliens where whipping those saucers around my house so smoothly

Da**************:

I once worked in a "Steel Mill" and we used to lift and move sheets of Steel weighing several Tons with an electromagnet powered by a 12v DC Car Battery.

Re**:

Wait, isn’t the hyperloop just a billionaire boondoggle that would be a dangerous if any length were ever built?

LS*:

I have a cape that works with the earth's magnetic resistance... I use it on the weekends

pa******:

Instead of physically rotating a bunch of magnets, couldn't they just use an array of coils energized in sequence to produce the same fields? (Think along the lines of induction motors.) A couple sets of transistors in parallel (to handle the current) to switch each coil, and then you have something solid-state with no moving parts.

Now just make that copper plate into an inverted V shape, and bank each pair of magnets and it should self-center to make a working track of inverted-V sections.

Still this system isn't that efficient if anything has to hover in place without moving, too much of that energy is wasted as heat from the resistance of the eddy current.

Ke******:

we need a new version of air hockey with this technology! (as long as we can counteract the heat)

Sp**********:

I couldn't imagine wasting my life by working for a hyperloop company.

Ca*******:

Bruh I’m only 10 pounds heavier than this thing and I’m nearly an adult...
Feels bad man

Mr****:

Someone finally applied it, hope to see it evolve in my lifetime. Great job!

fa****:

Wouldn't it be possible to replace the copper plate with a superconductor material and cool the thing down until the resistance in the superconductor becomes 0 and therefore eliminates the drag, so the whole system could work a lot more efficient? Or am I misunderstanding this?

Ji********:

Yes, because getting to another city in a day is impossible now.
