Wireless Electricity | Part 1 | Bang Goes The Theory | Earth Science 

It is cool but seriously whats with the weird camera shakes and sounds ? I really don't think its necessary.

Rumors say that Tesla was trying to harness the electromagnesity of the earth as well. Free Energy for all!

I've actually built several tesla coils like the one shown in this video. Although they are still impractical for powering homes, they aren't as dangerous as Jem makes them out to be here. While filming one of my tesla coils for my youtube channel, my dad accidentally got zapped by a few hundred thousand volts. He was fine. I have actually touched smaller tesla coils while feeling very little pain and no lasting damage.

OK, interesting intro, now where's the main video?

Well, thats exactly how transformers work. Just different sized coils.

Wireless power is far less efficient than wired power and generally people leave the wireless chargers switched on constantly, meaning they are probably using 10 times more power than if they had to plug in a charger. Hardly good for the environment and we are short of electricity as it is, so perhaps we should develop these solutions a little more before offering them to the public to avoid huge waste of a precious resource????

"precious little power loss" is an extreme exaggeration when it comes to power distribution by cable. There are HUGE losses, but compared to Tesla's "wireless" transmission, they are small.

Tesla coils are hidden until a unit comes near

Really nice demonstrations of that technique. I wish it hadn't been filmed in the style of a crime drama. Some decent shots of the rig without the camera flicking back and forth would be nice.

wow, amazing!. thanks!.

'Brit Lab', uses feet for measurement??

can we please have a link to the full video

really?! just when you got me interested :(

single coil can transmit power to a distance to itself, distance in time that is, that is how oscillators. work.

This is old research, nasa had put out a bulletin and reward for anyone who knew about this stuff ages ago. Still cool though.

TV producers should take this in consideration and we could finally have wireless/plug-less tv's.

Why the weird big cirle in the final form? Is that still a coil?

Quite interesting, so wish they'd have taught such stuff in school, it would've been more interesting!

part2?

Never connect a battery to a transformer with a load (as shown @ 02:50) it is highly dangerous for the transformer, the load and the user.

wheres the rest?!

What the hell is up with the visual effects?

elactrizzatey

now you just need to some how focus the magnetic field

so why not say its the basis of a transformer , which is what the toothbrush uses etc..

Shortwave radio?

In the first moment ,humanity fallen clean- call comfort At the second the psyche turns into hands-clean but unsafe if products in the rechargeable time got stolen.... No way the good oldfeshioned electricity flow-line -cable - gave me more.... Humans in our countrys washed their hands....and with very inteligent/smart surfaceses at cables.... To recharge is very safe and highest grade in wellness! B

Feet!? Really!?

Ahh the old inverse cube law.

sees part 1 predicted sudden stop at the end get intersted video ends

if only i watched this before my Physics O level paper

Tesla was not in any way mad, he was a genius who accomplished more than Einstein.

Common misconception is power travels down wires. Teaching the world wrong still 😴

dont perople in the uk use the metric system

Why do we get knocked out

Nikola Tesla was not "slightly mad". He was just as depicted by the general public, who did not understand his inventions. And as we know, if the "majority" something is not understood, it automatically is strange, because breaks with certain standards. For most were among the professors and scientists who rejected his brilliant ideas. All the bankers of the time he blocked funds. This man was a physicist, a more experienced virtually than Albert Einstein. He had a photographic memory, he spoke six languages. Nikola invented the radio, alternating current, laser radar, wireless communications, weapons based on the stream of particles, brushless induction and synchronous motors, wireless control, electrical works and much more. He was the most brilliant man of modern times. So please stop spread this propaganda.

we do have wireless energy transfer its called radio its been around sense tesla invented it

Video's great, until it comes to anti-climactic end...

An cable have more comfort, because users could fix the car in an parkbox like bikecycles! That's much more higher preventative in the view of disordering law-acts in intensive criminals..... But protection mony-mafia like this way!!!!!!!!!!! Ornt so?

why not radio waves?

someone just cuts the grounding wire and the host is dead

junckers said there are aliens

And now come the idiots claiming that this is prevented by big companies. Never mind that Tesla didn't invent the transistor capable of fast switching at the time he wanted to make a world wide wireless electric network.

im annoyed that I didn't figure out that magnets can be wireless power earlier

Just like the rest of the video it seems... : (
