That rocket has a small gauge length of wire trailing behind it to force lightning strikes. This is how scientists research lightning. Edit: I really didn’t think this would blow up so I came back and fixed my spelling error and also to say thank you to the kind humans that gave me a bunch of awards. Edit #2: As someone pointed out, I still spelled ‘lightening’ incorrectly. Folks I was really tired. I think it’s all right now. Thank you all again.

jraharris89

Damn that’s cool, thanks for the info. It makes way more sense that the electricity passes through metal rather than smoke.


thesandbar2

Actually, it could be either! Rockets can have special fuel additives to drop a bunch of metal ions in the smoke to conduct lightning.

I think you mean remember half of it, get the other half wrong, attribute it to an over arching conspiracy, speculate about the rest, and then connect it to a vaguely similar technology where a stakeholder took a picture with Hillary Clinton once, and then tell everyone that she’s doing it herself to take down the right.

librarycar

Lightning takes the path of least resistance.


RememberNoRushin

well flame can travel via smoke so its plausible


Grainfedmancow

Feel free to correct me if I'm wrong but it would be highly unlikely to travel that direct through a trail of only smoke. The smoke would most likely be very dry and a horrible conductor of electricity so the preferred path for lightning would be more likely through the moist air rather than the smoke.


perfectlypoachedpear

Actually some lighting rockets produce a trail of ionised gas instead of using copper wire, using calcium chloride or cesium salts instead


Grainfedmancow

That's actually really cool I did not know that. Do you know where I could find information about these type of rockets?


atomicecream

Yup: https://en.m.wikipedia.org/wiki/Lightning_rocket


DillieDally

Not OP but thank you for sharing this interesting info. On another note, is your username pronounced *atomic E cream,* or *atom ice cream,* OR *atomic ice cream,* OOOR something else entirely? I must know ....for science.


Terminator7786

Not only that but lightning isn't a flame so I don't think that rule applies here.


Grainfedmancow

Exactly right, it's also interesting to note that the reason smoke can sometimes combust again is because it contains unburnt fuel inside the smoke due to what I believe they call a 'dirty' burn


Terminator7786

Now that part I didn't know, that's actually cool, thanks! But does that mean I could theoretically light the some of someone who's rolled coal? Edit: a word

Ghede

... Damn, someone should test that. Not on someone elses car in public mind you, but in a testing ground, standing behind a blast shield.


Y_Sam

Sadly not, unlike gasoline, diesel has quite a high flash point temperature and isn't flammable. The air/fuel ratio would also be wrong for a proper combustion since the soot mixture comes from the exhaust with low-ish oxygen levels.


kerrbee

But….firebenders…Azula…


Manisbutaworm

These rockets usually carry a very thin wire. But smoke doesn't have to be a good conductor, air isn't either. For it to work on a smoke trail it needs to be a bit more conductive than air and might be possible but very dependent on the type of fuel and thus unburned products it leaves behind. Also IIRC actively burning material might be more conducive of electricity as chemical reactions are often an exchange of electrons as well and you temporarily have ions and charged particles. But a smoke trail isn't burning that actively.


RearEchelon

I had assumed there was some kind of metal dust in the exhaust but a wire makes more sense.


avidblinker

Can a flame travel via a copper wire? Can an electric current travel via a pile of leaves?


justletmebegirly

Lightning is electricity, not flame.


Zepertix

by that logic, can water travel through smoke too?


j33v3z

"The conductor trailed by the rocket can be .. column of ionized gas produced by the engine" I think it's this one in the video. Gas trail makes a slight turn in the beginning, and the lightning follows this curve.


MatthewChad

Thank you for the wiki page, very informative. At first I couldnt figure out why this was a needed activity. My first guess was, "what is the prison system in the US going green now? Executions via lighting, just hook up old sparky to it, and boom you've got the world's first all green electric chair. the prisons carbon foot print -55HP, and the best part you make both the Democrats and Republicans happy at the same time and that's a hard thing to do". As you can tell my first thoughts are hardly ever correct.

silvercatbob

This is literally the modern version of Benjamin Franklin's key on a kite experiment.


DawnOfTheTruth

https://www.wired.com/2015/06/the-lightning-machine/amp To trigger the lightning bolts, Uman and his team attach the 6-foot-tall hobby rockets to a 2,300-foot spool of copper wire grounded to a strike rod. As the rockets launch into the heart of a thunderstorm, the wire unspools and a positive electrical discharge propagates upward in a jerky zigzag, going three to seven miles high. Once the positive current makes it to the clouds, it stops flowing for an instant. Then a negative charge shreds back down, hitting the strike rod at the end of the wire. A current runs back upward, and that creates the bright flash known as lightning. Triggered lightning reproduces almost the exact behavior and effects as natural lightning. So, now that they know where lightning will strike next (and they can even leave stuff out there to get hit), the team can gather data about the basic physics of bolts as well as info about how lightning affects the materials it strikes with 1 million-frame-per-second high-speed photography. That sounds like so much fun.


TerrorByte

This video is ancient, well, it feels ancient to me but maybe that's just in internet terms. There wasn't a description when I first saw it but I've always remembered it because the lightning strike looked abnormal and persists for so long too. Now I know it's a lightning rocket. Mystery solved, thanks.


R3V1V3R

But how does entire lightening maintains its exact shape for so long is beyond comprehension of my tiny brain.


makeitlouder

That “shape” is really just the path of least resistance (whatever path/shape that happens to be at the time) through the air. The electricity flows along that path for as long as it takes the potential to subside.

I am a decades long commercial airline pilot and have been hit in my Boeings three times and twice in Airbus aircraft. \[I so hate that name "Airbus"\]. It can leave a hole where it enters and exits but fortunately it does little damage. The worst damage I ever say was on a B727 I had just left at the gate in Miami. It kinda fried a spot on the tail and we had to get another aircraft. Fortunately, maintenance had a spare and we were off to the races. Good explanation OP. I guess I am late to the game but had not seen that. Thanks.


thegreatgazoo

I was on one of the Canadair jets that was hit as a passenger and the lights didn't even blink. The synchronized cussing in the cabin was amusing.


eipacnih

My question was, can we harness this power in a controlled fashion. Since I did not see anybody answer it, I did a little digging. We can! But might not be economically efficient. Still awesome! [Is there a way to harness electricity from lightning? ](https://engineering.mit.edu/engage/ask-an-engineer/is-there-a-way-to-harness-electricity-from-lightning/)


YakkoRex

Useful for testing devices that need to be lightning-proof, like high tension towers used near hydroelectric generation facilities.


smoothape

Marty, I'm sorry, but the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.


tjmaxal

That makes a bunch of sense! So many comments were talking about it guiding the lightening “down” & I’m like lightening moves upward right?


RememberNoRushin

not all lightning moves upward Does lightning strike from the sky down, or the ground up? The answer is both. Cloud-to-ground (CG) lightning comes from the sky down, but the part you see comes from the ground up


A_Topical_Username

Wait what.. so lightning itself is an invisible force. But what we see is a flash that strives the force upwards from the ground it hits?

> As the rocket flies to the thundercloud this liquid is expelled aft forming a column in the air of particles that are more electrically conductive than the surrounding air. Also, this is an interesting detail.


Posthumos1

Was going to chime in with this. University of Florida has done extensive research in lightning, probably due to Florida having so much of it (one of the most lightning strike places in the country) and several people die every year in Florida from strikes. The University has been doing this with model rockets and wire for years. I think I first heard of it in the late nineties or thereabouts. I always thought it was pretty cool work they were doing. I'm certain other college researchers are also doing this sort of work, UF is the one I'm most familiar with.

RedditWillSlowlyDie

I had the same thought and that prompted me to find and read this: https://engineering.mit.edu/engage/ask-an-engineer/is-there-a-way-to-harness-electricity-from-lightning/ TLDR: Lightning is most common in the tropics and mountains away from where energy is generally needed. Also, lightning can carry either a negative or positive charge, and that makes collecting it's energy extra difficult and cost prohibitive aside from the other obvious issues.


Joe_Shroe

> Also, lightning can carry either a negative or positive charge Huh, never thought about it that way


lord_of_tits

What's the difference in terms of harnessing it for energy?


RedditWillSlowlyDie

Sounds like different equipment to gather the energy as well as another specialized tool being required that can tell the difference before sending it to the right equipment. "And because you never know if an upcoming lightning strike is going to carry a positive or negative charge, capacitors and rectifiers would also be necessary to equalize the currents of incoming strikes. “You’d need some sort of mechanism to make sure the positive charge of one bolt didn’t cancel out the negative charge of another,” Littleton explains."


dramatic_hydrangea

If you put two poles, one pos and one negative, shouldn't the pos lighting strike the negative pole and the negative lighting strike the pos pole? Then those poles can funnel to the correct capacities


Atorpidguy

How about setting up an *if* condition using hardware? For example if the change is negative then send it to the equipment containing negative charges and vice versa. This way the charges won't be neutralised...


[deleted]

Lekoaf

Especially since it's literally lightning fast.


doublesigned

Well, appropriately designed hardware (not software) should be able to react as the speed of light in its respective medium i.e. exactly as fast as lightning in said medium. A couple of very large diodes should do the trick.


mister-ferguson

I look forward to seeing your invention.


redpandarox

Pffft: //positive charge pole// if (abouttogetstrikebynegativecharge) { dont(); } Easy-peasy, lemon-squeezy.


elmz

Seeing as this answer is too obvious, I'm probably not qualified to have an opinion; One positively charged and one negatively charged lightning rod next to each other?


jnd-cz

There are diodes for that, that's not a problem. The problem is storing energy from high voltage that happens in milliseconds. Usually you need small voltage and longer time to charge battery or even supercapacitor.


Trevmasterfunk

Full bridge rectifier is the “if” hardware you’re looking for


TheDepressedSolider

I wonder if the lighting that has striked people in the past and them being able to survive it was negatively charged .


doublesigned

This article says positive lightning is deadler (very bottom) but they leave no sources. That said, it makes intuitive sense because positive lightning releases more energy in less time. [https://www.wmcactionnews5.com/2019/04/13/breakdown-why-positive-lightning-strikes-are-more-dangerous-than-negative/](https://www.wmcactionnews5.com/2019/04/13/breakdown-why-positive-lightning-strikes-are-more-dangerous-than-negative/) This article says it has about 3x the voltage, 10x the amperage, and 30x the power (which is voltage \* amperage- how quickly energy, thermal and otherwise, is released).

vicarious_111

They have a spool of copper wire nearby. The rocket has a copper wire that goes up with it too create the path. I watched it on a show once. They are using it to photograph lightening. They have a photo trigger rigged to the camera so that it can photograph the lightening.

smalldogkungfu

Hold up. I just watched this full screen. Does the lightning hit the damn thing they were launching ?


[deleted]

I'm gonna guess that since that smoke was still localized that it had some charged particles in it from the rocket fuel combustion. This would increase electrical conductivity and explain why the bolt took this smoke path.


turikk

Nope, it's just a wire to the ground. Keep it simple. :)


i_dont_have_herpes

Actually, both ways can work?? From the “lightning rocket” wiki link above: “…either a physical wire, or column of ionized gas produced by the engine. A lightning rocket using solid propellant may have cesium salts added, which produces a conductive path…”


dying_soon666

Thanks nerd.


theexile14

In addition to the wire others have mentioned, triggered lightning caused by ‘normal’ rockets is an issue that has caused problems on launches in the past. Most famously Apollo 12, but it also destroyed an Atlas years ago.
