Dave uses a microscope to examine the shattered LG Mono-X solar panel. Was it a micrometeorite or larger meteorite impact?
General consensus now seems it's a larger meteorite.
Micrometeorites do not have the impact velocity required.
And what are the odds of a micrometeorite impact on a typical solar power installation in a given year?

Hi just a follow up on my shattered LG Monox uh solar panel from my ruse and I done previous videos on this and people wanted me to actually investigate under the microscope the impact down here. so that's exactly what we're going to do today. I've got my and and star uh USB microscope here. we're going to uh uh, screen capture some uh stuff from that and have a squiz inside to see if we can figure out what actually impacted this thing.

Now the current theories are uh one which I don't really subscribe to. which is the cricket ball and if it is a cricket ball, uh, there should be some red residue left over cuz Cricket balls here in Australia they're red and uh yeah I I don't think it is I think it's a much sharper impact than that. uh, the other one is something that fell from a plane, either a bolt or some ice or uh, something like that cuz I am near a flight path here or as everyone's favorite Theory seems to be it's a Micr meteorite. well is it h Let's see if we can find any residue here or if it's not a microm meteorite could be aliens.

Yeah, aliens. But of course one of the problems with doing this is that I don't know how long it was up there. Uh, after I actually discovered it, it was still up there for like many weeks and it rained and poured and all sorts of things. So um, there's a high likelihood that any uh evidence in there has since been uh, washed away.

but you never know there could be something, uh, stuck in there between the uh, glass shards and and things like that. But it seems obvious that there is some really sharp impact there rather than a cricket ball. It looks, you know, like really something. uh, sharp and violent.

So like, yeah, like a steel Bolt from a plane or a micro meteorite. because well, I haven't done the um, haven't researched the figures on this. Maybe I will, but uh, when? I go edit this video to see how likely a microm meteorite impact actually is. I Mean it's It's incredibly unlikely, but it's a nonzero possibility.

So anyway, we'll get the Uh microscope in there and have a squiz. Okay, let's have a quick uh overview of this thing. Hopefully I've got this uh in focus. It is quite hard to see on the Uh screen out here now.

Um, yes, I've got it in like highest resolution 1,600 by 1200 or thereabouts. So it's only a couple of frames per second. But I want the greatest resolution possible? so please excuse the uh, the poor update in here. Um, because it's not going to be pretty I'm only getting like three frames per second or something like that.

So actually it's dropping a lot of frames too, which is not great. but anyway, we can see if we move around there there's nothing obvious around the outside if it was a Cricut ball. Cricut balls are quite large and I would have expected to see some, uh, some red, um, some sort of, you know, some sort of residue. but I can't actually seem to I can't see anything in there at all.

and if we go out towards the outer outer edges, there still nothing. So it seems like it's it. could have been a sharp object that impacted and then uh, took the rest of it with it. You know, like I'm You know, certainly not going to be pretend to be an expert on how this thing uh, would shatter with various different types of objects, but it doesn't seem out of the realm of possibility that it would be a really sharp object.
Now you can see directly in the center there that there looks to be some sort of brown. Is it brown? I don't know. Maybe I can't see it on the screen here, but some sort of brownish thing. So I will now zoom in closer and uh, see if we can investigate that.

Center Spot And here we go. Hopefully that's in focus and yeah, it, it definitely looks like there's some sort of really tiny sharp impact there. I Mean that is not a pattern that I would have expected if it was like a Cricut ball sized object. What? The well? actually I don't actually have any measurement.

Um, on this. Maybe I should actually get a ruler to. uh, put that in there. Hang on.

So what you're seeing there now on the ruler. they're half mm increments so as you can see it, you know something really small seems to have impacted that. So this I think lends credibility to the microm meteorite. um Theory I mean there's some looks to be something really off color in there and it really seems to have been a really sharp pointed object.

Well now check it out. This is uh, zoomed in once again and I can see some little what looks like little tiny particles there. Really weird I is is it is that actually part of a microm meteorite? It'd be awesome if it is. um I there little particles in there.

but I I'm pretty convinced that this is a really sharp pointed impact and it's just taken the rest of it out with it. I mean if you have a look there, it's just you know if it hits the center. I don't know how it's taken out this ring around here like this, but that could just be properties of the glass and how it's uh, shattered and things like that. So um I I don't mind that theory at all.

cuz I wouldn't have expected something so sharp like that from a uh, a large curved object like a C cricket ball. It's just not something that I would uh expect. So there you go that that that's half mm increments there on the fuzzy out of focus ruler. but yeah, Interesting.

Okay, I've got a little bit faster. uh. updating now. I've gone to 800 by 600 and which means that we can probably move this around.

This might be better actually. Look, there's another yeah, look, there's some. There's definitely some objects in there. you can see those dark, dark objects and now that I look around, can actually see quite a few of them.

You can probably hear a plane going overhead now. uh, they're They're not that common. I'm not really. Um, in a flight path like I'm I'm near a flight path, but uh yeah, it's not a really, uh, well trodden one and it's like 30ks out from the airport.
Port So um, they are significantly High by the time they get here. But look, look at all those particles in there. look at that that is. That is very unusual I'm is that a Little Rock I Don't know what type of impact or what size object microm meteorite would do that, but there definitely does seem to be some residue of something left over there.

See if I can get even closer. This is not the world's best microscope I Can't use my good microscope at the lab because I can't really. it's hard to get the solar panel under under it, of course. So, but yeah, there we go.

Here we go. They just. they definitely look embedded. They look, they look embedded.

I don't think they've come down in the last shower I think they. they're well and truly embedded in the glass. Whatever they are. I Reckon that is a genuine Space Rock folks.

So I am pretty darn sure. this is not a cricket ball. So and metal. If it was like a bolt falling from a plane or something weird like that, maybe a dead bird falling from the sky.

I No. I think we've got ourselves a meteorite impact. It's got to be now. This is probably the best magnification I'm going to get on this thing.

so look at that. They're definitely embedded in there that's right smacking the center. Look at that. I think I've been lucky enough to have a microm meteoroid impact.

It's got to be it. Let me know that there's any experts out there. Please let us know what you think that is. Because I damn well think that it is a microm meteorite.

Either that or it's aliens. So that has to be the most plausible Theory because like I am seeing uh, objects directly right in the center where that thing hit and sure, it's been washed out, uh, rain many times since then. But uh, I reckon that uh, it's impacted straight in the center. there probably only tiny, like, you know, 5 mm across I don't know.

guessing something like that. Um, because you know the energy. uh, would have been incredible if it's like you know the size of a golf ball or something. Uh, probably would have gone right through.

but um, yeah. I can show you the uh back of the panel. It didn't get a good closeup last time. so I'll show you the back, the pattern on the back of the panel.

Now this is going to be hard to see, but there's like a an outer pattern like that and there's like an inner lump. But interestingly, I can feel that bit right there. That is definitely a very, very sharp impact. I can feel this big raised bump there.

like, well, big like I can feel it. Okay, it's a tiny tiny little tiny little bump and I can actually feel that. I it's got to be microm meteorite. That tiny little thing.

as I said, it could only be like millimeters across by the time it got. uh, got to ground level here. but cuz most of them disintegrate before they hit the ground. um but jeez, yeah.
yeah. I Have no doubt if it was a bolt or something bigger, it' be different. It's definitely not a cricket ball. definitely not.

So there's just a ruler. The to the outer one's about seven. CM or thereabouts. and uh, no, by the way, it is not a bullet.

Somebody hasn't fired a bullet. This is. Australia Okay people that don't just randomly fire, they basically don't have guns, let alone just randomly fire them off. Okay, it just doesn't happen.

So uh, it, it is not that. Now if we just do some quick math here, which I'm sure somebody will point out if I've goofed this up. Uh, let's take a look at Micr meteorites on Wikipedia here and well, you can go deep in and verify the numbers and things like that, but we'll just go by what we've got here now. Approximately 10 to the power of 17 Micr meteorites into the atmosphere every year.

Uh, about 10% of those actually hit the surface as microm meteorites. They're microm meteoroids. if they're actually in space. they only become meteorites when they actually hit, and approximately 2700 tons per year makes it to the surface.

Well, tons isn't very good, so we'll convert that to Uh Gr. that's 2700 * 10 the power of 6 G per year. Make it of the service so we can work out the average uh weight of a microm meteorite and that turns out to divided by 10. Power of 16 turns out to be about 270 * 10^ -9 G on average per meteorite and we look up the top here.

Um, that second red mark. Um, they Reon individual microm meteorites weigh between 10 ^ of - 9 and 10^ of 14 G So that figures somewhere in there. So we're in the ballpark and then uh, if we take the Earth's surface 510 million square kilm give or take, Uh, we can convert that to square M 5.1 * 10^ 14 square m And well do the simple Uh, Division and you get an average of 392 microm meteorite impact on my 20 square met solar array each year. That's more than one per day Now of course.

why isn't everyone's um, solar array shattered right? Mine should. If mine shatters, you know roughly every year gets hit every year, then everyone else is should as well. These things are incredibly rare. Well, it's almost certainly.

of course. obviously because there's just not enough energy in most of these. They only the average only weighs 270 * 10 ^- 9 G And well, I'll leave it up to everyone else to go and calculate. you know, based on the velocity and the impact force and everything like that.

And my LG Monox uh panels are very rugged. They're designed for like, you know, golf ball or tennis ball size, hail to hit them and not uh, shatter they're They're actually rated for 5400 Pascal so you know if you con that's a uh, that's a pressure of course. So you convert that that's about 5 50 kg per square meter. And of course you could scale that down to a little impact size, but it's going to be not accurate.
But anyway, um, just because. yeah, it's designed as a sheet impact. so I don't know if they actually have a spec for a point impact or not. But yeah, 550 uh kilos per square meter so you can kind of sort of maybe back of the envelope.

uh, work out what you need in terms of um, a Micr meteorite uh, weight given the velocity? I think I saw somewhere 11 km per second or thereabout. so you know you can calculate uh, the point energy and all that sort of jazz. But I'll leave that up to you. But there you go.

that is a lot of microm meteorite impacts I was actually shocked at that. Um, but they're all too small to really do any damage. but hey, I got lucky he So there you have it. I Think odds on this is a genuine Micr meteorite impact.

What are the odds of it happening to me? Um, you know who blogs about this sort of stuff? But anyway, definitely Micr Meteorite. I reckon I'm 90% sure that's what it is now, but Iy I This is my first Micr meteorite impact. I You know I'm a bit of a noob, so if you've got any other better theories or uh, anyone you know, like knows about this sort of stuff, a few um, people actually analyzed the Uh patent and said uh yes it it would be a very sharp impact. It's not like a ball or something like that and seems to back it up.

There's some residue in there which looks granular, dirty. it's it's like almost like a rock. Although I have to review the footage, it was hard to see on the screen here. uh, out in the sun.

But yeah, micr medor right. Impact Awesome! I'll leave a link to the EV blog Forum down below where you can discuss this or leave it in the comments. If you've and you're an expert in this field and you've got any better suggestions but odds on I Reckon Awesome! Catch you next time.

    Perhaps somebody threw a knife at your roof😂

    If it was left on the roof for a few weeks or more than the particles stuck in the glass would be just dust

  3. Avataaar/Circle Created with python_avatars Michael Decker says:

    This is just silly. Any astrologer will confirm that the southern hemisphere never gets meteor hits, because it's underneath.

    You got your x4 microscope some people call it magnifying glass and you are looking for alien civilizations. |Wrong mind

    What about a bb/pellet gun? Alternate theory a magpie went super saiyan took it out with one peck.

  7. Avataaar/Circle Created with python_avatars DJkayoo says:

    I think micro meteorite would have penetrated the solar panel maybe even the roof underneath of it .

  8. Avataaar/Circle Created with python_avatars Jonathan Brown says:

    Not sure how I've missed this 5 year old video but there is no chance a micrometeor could maintain enough velocity through the atmosphere to cause that damage. You're not living on a space station.

    Could still be a meteor strike but the fragments would still be around

    Send it to applied science and have him go an Auger elemental analysis on the brown residue.

    Someone threw a rock. That stuff is clay and debris from a rock. I'm not a micrometeorite expert but I'm an expert at throwing rocks at peoples solar panels if I don't like them. 😛

    Ayy lmao

  13. Avataaar/Circle Created with python_avatars chillzwinter says:

    After your earlier comments about how your crazy neighbours spend so much on electricity in your area – I'm sure its just one of them throwing a rock over the fence.

  14. Avataaar/Circle Created with python_avatars 46I37 says:

    I found a bolt embedded in the side of my house: cause, council mower flinging debris from the park.

  15. Avataaar/Circle Created with python_avatars Jeffrey Morrissey says:

    If it was hit by an object from space, then it was hit by a small iron meteorite; and it appears there was melting and vaporization. That’s why there were the spherical objects lodged into the broken glass.

  16. Avataaar/Circle Created with python_avatars Jeffrey Morrissey says:

    On thing for sure is that the panel was hit by a fast-moving, small, dense object as that dent on the back of the panel was very small but well-defined.

  17. Avataaar/Circle Created with python_avatars Jeffrey Morrissey says:

    Aren’t solar panels designed for hail impacts — at least of a certain size?

  18. Avataaar/Circle Created with python_avatars Mr Mr says:

    hailstone…?

  19. Avataaar/Circle Created with python_avatars Mark Hodgson says:

    Dirt on landing gear of aircraft

  20. Avataaar/Circle Created with python_avatars Mark Hodgson says:

    Bb round

  21. Avataaar/Circle Created with python_avatars Les Hemmings says:

    If you can get those particles to a mass spectrometer then iridium would be the giveaway for an extraterrestrial origin.
    It's how Alvarez pinned down the impact that wiped out the dinosaurs. The KT boundary is laced with iridium worldwide and it's not naturally available on the earth's surface but it is present in meteorites.
    Iridium is the clue for a space rock but…
    Anything that small coming in at interplanetary speeds would lose all it's energy to heat on the way in. By the time it reached the ground it would be at normal terminal velocity.

  22. Avataaar/Circle Created with python_avatars cathode follower says:

    That impact was from a small particle traveling at extreme velocity. you could never do that with conventional objects.

  23. Avataaar/Circle Created with python_avatars NeoMorph WTH says:

    Ice chunk off a plane would do this.

  24. Avataaar/Circle Created with python_avatars Vik Table says:

    maybe frozen shitsicle, from plane?

  25. Avataaar/Circle Created with python_avatars Brian Arundell says:

    going to be a rock flung from a lawn mower

  26. Avataaar/Circle Created with python_avatars t T says:

    Golf ball for sure. Some psychopath practicing they're swing with swamp balls in your neighborhood. Micrometeorite's are going ridiculously fast, high velocity equals penetration power not impact force (Clean entry hole not radial energy distribution.) Google image search; golf ball windscreen looks identical. P.s. sorry

  27. Avataaar/Circle Created with python_avatars metallitech says:

    An egg-shaped micrometeorite came through our window once and made a mess on the floor.

  28. Avataaar/Circle Created with python_avatars BangDroid says:

    Some idiot made a golf ball cannon and shot one in the air

  29. Avataaar/Circle Created with python_avatars SiXiam says:

    I think it is blue ice from a plane. Frozen sewage.
