One of the most epic things ever seen.
I love how everybody cheers and gets happy when the lightning happens! This is so awesome!
@UltraBibendum : I take the video from the site of Research of the University of Florida and I publish it. See the link in the video description.
I would love to be there watching one of these experiments in person.
@UltraBibendum : are you a physicist specialize in lightning) Have you ever read one of their publication? lightning.ece.ufl.edu/general.html#2
@cptkostya thanks, happy to have seen it!
@UltraBibendum : why? Explain, please.
This is superb! I'll be spooling through this frame by frame to recreate the effect for a game I'm working on.
@kokilot : What??? It's a Research of the University of Florida!!!! See the link in the description of the video, before talking,
@WhefXLR Oh, you rebel, you!
@KrikeTube7 IT'S SUPER EFFECTIVE!!!
@MrFeelingAwesome Lightning is a movement of electricity from the clouds to the ground, or the ground to the clouds (it happens so fast it looks about the same either way). As the clouds move in the sky, they gather electrical charge, which can be thought of as a kind of pressure. Air, however, is a 'dielectric', which means that it resists electricity pushing through it, sort of like a dam holding back water that would otherwise flow downstream. (continued...)
Teasing Thor
woah dude 😂😂
@UltraBibendum : so educated. Thanks to prove your ignorance.
@Warrior536 LOL! Awesome.
@MrFeelingAwesome They wait until lightning is about to strike (using special measuring gear) and then launch a rocket with a wire attached to it (and to the ground), when the rocket goes up it becomes "the best path to earth" for the lightning.
Incredible!!!
Love the LRG! Stuff like that was what made me decide to pursue a career in meteorology. Keep up the research and maybe I can be there once I go through grad school (after I finish the second bachelor's) :D
Would this help in potentially enabling us to harness lightning as a power source?
I wonder who invented that... they must have been pretty proud of themselves. it's like you're zeus himself! :o
@Rikus84 You edited the video
@VirtRampage Are you absolutely positive about that?
As someone living outside of the US: We're doomed. :p
Cracked.com lol
@MrFeelingAwesome The rocket either carries a wire trailing behind it, or leaves behind a trail of gasses which are less resistant to electrical movement. Either way, it creates an easier path for the charge pressure to get across. Following the water analogy, the rocket is like cutting a hole in the dam at a specific place - that way you know where the water will come out.
Daily dose of Internet where u at
You can see a second trail of smoke from the vaporized wire in the second launch. Cool!
nice
2 in The Vatican Don´t like this... :P
Pissing off Zeus with SCIENCE!
@Rikus84 its fake
@davidls11 helium balloons would take to long to get up there, but you tottally could.
Time to get that Lichtenberg scar!
Pikachu uses Thunder!!
how high would the rocket have to go?
It is my understanding that lightning travels from negative to positive, and since the earth is one big ball of negative charge, what we are seeing here is the true nature of lighting.... what is visible is the heated pathway,from clouds down, but in actual fact the electricity strikes from the ground up which is invisible, the bolt downwards is just the connection that is made which looks as though its striking down
could it be possible the fuel consisted of Hydrocarbons (Carbon) and since carbon has a stronger ability to carry electricity than air.... it may be the discharge was facilitated by the carbon laced smoke of the rocket launch?
+DawnUSNvet nope, the rocket was trailing a thin copper wire
wire tied to a rocket... thats some high tech
I saw on tv a long time ago, this guy would fire rockets spooling out wire to get a lightning strike into this pit of wet sand to create this melted glass art he would sell. Can't find it on the net though. Was many years ago.
+Richard Walsh Try to search "Fulgurites".
I'm having fun imagining a car powered by this, and how it would prolly leave divets in the asphalt wherever you fire off a rocket to juice up, hehe.
Maybe a stupid idea but could we capture the energy somehow? Maybe into large capacitors or something?
designing my own launch mechanism now. just have to design a stable rocket. the wire spool on the back is really heavy.
استغفر الله العضيم. سبحان الذي يسبح الرعد بحمده والملائكة من خيفته
So cool!!! How much air pressure does it take to launch the rocket?
Those are some stoked scientists
Did they get 1.1 jigawatts of power? I wonder if the rocket went back in time.
why do lightning bolts flicker
Brian Kelley good question.
I thinks it the oxygen around the bolt burning at different speeds.
In the open ocean, would a similar rocket attached to a wire (or resistor) fired into the top layer of hurricane (assumed positive), create rain that is negatively charged in the top and middle negative layer to disorganize the bottom layer (assumed positive), and, if repeated, dissipate the hurricane?
The amount of energy in a hurricane is roughly the same as the entire world consumes in a year. The average power exceeds 10^17 Joules per day. A lightning strike dissipates about 10^9 Joules. Basically, you'd have to send up over a million rockets to make any kind of difference.

For those that don't get the object of this, its University of Florida and they have a program where they fire basically large model rockets that have a spool for copper wire at the bottom that is attached to the ground. They have "electric potential" sensors that can sense how much of a difference between between the cloud and ground has built up. When it hits a certain level if they fire it should trigger the lightning. It's a black art to time it just right and very hit and miss.
It's basically the same thing that happened on Apollo 12, NASA launched into a cloudy and rainy (no storms however) November day. As the rocket entered the cloud deck, unknown to all, there was a large electrical potential between the cloud and the ground. The exhaust coming out of the engines of the rocket were highly ionized (ie, had a charge, not neutral) and the charge in the clouds followed this right to the ground, striking the launch tower twice and knocking the spacecrafts electrical system offline.
NASA now has "field mill" sensors all over KSC that can sample the electrical charge level of the air and warn personal to leave risky areas if it gets to high. Even just a windy dry day can create a hazard of you're on the top of a tall tower.

How do they actually trigger the lightning, and why wouldn't they just run it up and let it strike when it's has enough?
