Uh... they did do damage even with cloud cover. Besides you could just blind the people (if you can catch the ship on fire just imagine what it would do to eyes.) Still a very useful weapon.
ONE:) Archimedes did not have the ability or technology to make parabolic mirrors of any kind...
TWO) Archimedes did not have silverplated mirrors available. Polished bronzeplates was the best he could do.. And in all the tests it was proven that polished bronze did not have the ability to reflect heat and light which modern mirrors does.
THREE:) What you are doing is simply showing what would be NEEDED to make a deathray... And busting the myth to bits..
How do you know? Where you there? Its impossible to bust any myths about history. We can only see what is plausible and this video does an excellent job of showing that the "myth" is plausible.

2: Actually according to the Mythbusters bronze would have been extremely effective and more of the better substances to use.
3: Uh... of course that's what they are doing. So?
I hope you understand that concept.. Silverplated mirrors didn't come about before WAY after Archimedes died, Parabolic mirrors weren't constructed in his days either. Bronze simply don't have the capacity to reflect light and heat as silver has..
@Bfrankenbergful Mythbusters most recent video used longer mirrors with 500 students, they leaned the mirrors on the ground causing them to flex into a mild concave shape. The optimal focal point of each mirror was about 20 feet, beyond that the diffuse to infinity. They were actually only using about 15% of the potential.
@GREENPOWERSCIENCE THANKYOU, THANKYOU, i am starting to HATE how mythbusters is doing things, the thing with the mirror and the hand, they swore it went straight down into the car when it actually crashed it with a head on collision, also did they not think that maybe the mirrors had to be parabolic for more focus. Sheesh.

@GREENPOWERSCIENCE Oh i also just noticed that in the video i asked you guys that had the chinese song, i just noticed that too was your channel. LOL.
I seriously doubt Archimedes employed individually adjustable mirrors, not because he could not have conceived it, but because it would have been difficult to explain on short notice. A few(or a few dozen) of his disciples who understood the principles would have provided the soldiers with something to aim for. For advancing troops the beam could widen because less heat is needed to dispatch a man, than to burn a vessel. About 200 degrees less. This principle also works with microwaves.
I inadvertantly caused tiny holes to be burned in a wooden end table in our living room by leaving a clear glass paperweight there. The sun did its work while everone was away from the house - fortunately, nothing else was burnt!

You can gather ball sockets from broken rear view mirrors at auto wreckers. I tried calling them but they are uncooperative. The only way you can get a lot of them is through grapevine of friends for free.There is a lot of broken rear view mirrors being discarded everywhere. Why ?? Why didi the autowreckers discard broken rear view mirrors and keep good used ones for sale?? Why give to the recyclers for remelting . The broken rear view mirrors still has useful ball sockets that is critical !

Get a glass cutter and cut mirrors into 500 or more smaller squares maybe one inch or two inch and assemble them all on a special constructed board with adjusting screws or ram mounts (ball socket) for each tiny mirror so you can have a powerful smaller portable death ray board. What is more , you can make more copies of them . See what 10 death ray boards can do to a target. You can probably burn a 2000-3000 degree F hole through a steel plate one quarter inch thick . I saw them.
not practical no sun light no weapon.. Ships of that day would have to know how to put a fire out . Lightning is common and this weapon would have been easy to deal with .Nice vid i really like this stuff.
Fire is one of the most dreaded dangers at sea. It always has been. Everything is so dry, and it spreads so fast.
If they set fire to the sail, the ship has a problem: it can't move, and is a sitting duck. If the sailors drop the sail, they're a sitting duck. If they wet the sail, they might be okay, but can they wet the top of the sail?
If the beam is focused on inside the boat, and in response they fill the boat with water, they go pretty slowly...
You always have such interesting videos. I think MIT and Myth Busters tried this and although MIT found it to be potentially feasible, it was highly impractical for a moving target.
Who really cares though; you put on an interesting demo.
Great video. One question. A mirror does not reflect 100% of the light that strikes it (disclaimer: I can not state this as a fact.) Did you consider this or care to comment on this?
@Bob06460 The glass absorbs some of the light, that is why first surface metal mentioned at 2:10 closes the gap between mirrors Archimedes may have used vs glass mirrors used in many recent tests. Most glass mirrors are 90% or less reflective depending on glass used and thickness. I shot a section explaining how glass mirrors are made but the video was getting too long.
The MythBusters have already revisited this, But You should submit this to them.....You are ABSOLUTELY right!!! this is definitely a realistic weapon .....Even if the ships didn't burst into flames, It would have been unbearable for the deck hands....No deck hands, no way to control the vessel. If you haven't already, I suggest you submit to myth busters!!
mythbusters tested the sail on water which is constantly moving, if a ship stood still for a long time with no waves or anything this could work.. it would be more viable from a balcony against oncomers
Bad ass dude. That is amazing. What is more amazing how some knuckleheads think boats are soaking wet. They have dry areas. You can follow anything with a mirror, even a car, boats are slow or stopped. Also RELIGION in those days, having that would be like seeing their God or something. They would crap their pants. Love the pirates. Denise, your shirt is the same color as the sail, nice touch.
@Films4You Finally someone brings this point up. If anyone happened to get near that focal point, they would get burned quite badly, and back then, getting burned by something intangible would freak an army out, for sure.
@DHarms07 Also that they could not see to fire guns at Archimedes side, ( a type od defence ), leaving the attackers even more vulnerable.
This would not require a high levels of Sun and be only needed for very, very short times. Try shining a torch in your eyes, from a distance, and the switching it off... It takes quite a while for th eyes to readjust before you can see anything. Time for Archimedes side, to take other actions.
Of course the reason this weapon didn't expand everywhere was it's dependance on the right sunshine. One thing though was when this is tested it is important to the testers it destroys or starts fires. Not so. I would think the sailors would have got out of Dodge as soon as the heat started cooking hem like baked chicken. That;s why the NWO has microwave crowd control machines like this one; search, HEAT-RAY CROWD-BUSTER on youtube

I think the movement of the ships would have presented a lot of difficulties. If they were becalmed it could have been made to work. Does that sort of weather pattern happen in and near Syracuse though? Also they probably would have focused on the sales since they would have been much easier targets to hit and equally easy to ignite.
Awesome display of sun power. Although I doubt Archimedes heat ray would have worked. Not because he didn't have the skills or know how, but because the ships are constantly moving on the water. It would have been near impossible to hold a concentrated beam of light on a small area, much less the amount of beams needed to ignite it. I'm not saying it's impossible. I'm saying it's unlikely. Nice video :)
Im sure its possible. You got to know that Archimedes had probably hundreds of soldiers to help, so if Dan and Denise alone with fev mirrors burned small woden ship even in few hours. Im sure that hundreds of soldiers could burn more than one roman ship in fev minutes. Fire spreads fast and if it grow bigger than spreads faster. About mirrors im sure that it was possible to make them efficient enough. People in those time wosnt less smart they had only less knowledge.
This video shows that mirrors and sun light can be used as weapons against ships. They also show the weakness of the weapon - it only works during the day with a cloudless sky and at short range. At short range the soldiers would climb out of the ships and stab you. These practical limitations means that such a weapon would only get used once.
This probably would have messed up the sailors on the deck before the ships, you could easily cause intense pain to someone with that or even blind them.
I can see Romans with buckets of salt water trying to drown out the flames. Your ship was static too. You've proved it can work in ideal conditions, now try it in less than ideal conditions. Archimedes would be proud.
@kitrana What do you mean that Archimedes' location faced the wrong direction for a heat ray device? As long as the sun is out, you can reflect it back in any desired direction.
@hughtub mmmm yes and no as i recall the hardbor for the city where he lived had natural cliffs surounding it so there were certain times of the day when this device would be utterly useless like dawn when invading ships would be more probable to attack
Even without flames and smoke, the light and heat could blind and incapacitate the enemy while other forces strike. If one thousand soldiers simultaneously directed sunlight reflecting shields onto the approaching enemy while another thousand just aimed their arrows at the bright spot.....yeah.. you bet I'd call that a death ray.
Even if it couldn't burn the whole ship down, it would certainly burn anyone who it focused on, imaging trying to run across a deck that is searing hot!
Great, now try it on a target that's covered in ocean spray, moving forward as well as up and down with the ocean. Also consider, a 200 ton ship with at least 100 crew on board, you'd find at least find one guy with a bucket of water.
Archimedes was a bright guy. He invented a hook on a swing arm to hook enemy ships as they try to dock that would simply pull one side of the ship up until the lower side swamped and sank the ship. He also invented a long screw water pump, they used to pumped the water to tanks above the docks. In an emergency, these tanks were designed so they could be turned over to swamp ships trying to attack the docks.
Do you know if the Mythbusters have been following these videos? I'm sure they'd be as impressed as I am. Great project, fantastic videos! I've told a lot of my friends about you. Thanks again, awesome job.
The soldiers could have used the focus to blind the other soldiers and to set the sail reducing the speed in which the ships could arrive increasing the time for the ships to sit there and bake. I think it is entire plauseable. Focus the framed mirrors on a pipe filled with oil drive a turbine.
Nice, I like the Mythbusters but honestly thought they were suffering burnout during their Archimedes video. I like how its made. They can polish bronze to a perfect mirror. Gold was polished to mirrors back then. Two things that inspire technology WAR and GREED. So I think it would be possible
I remember an episode of "Survivor Man" where he said that to aim a reflection toward something like a plane, for the purposes of signaling it, you should hold your hand out in front of you with a "peace" sign and shine the light between your fingers with the plane or object in the distance between your fingers too. I'm sure a group of soldiers could do the same thing or even build a scope on their mirrors back in the day.
well weather or not he actually sunk ships using this method there is another great effect it would have had. you could blind / cook the crew making the ship worthless
It certainly looks like a ship could have been ignited by this method, and I'm thinking it could have been a pretty effective anti-personnel weapon too.
I wouldn't have wanted to be on an invading ship with those mirrors turned on me.
I seen in another video where it cant be explained how an ancient wall/fort made of granite was partially melted, some think it was concentrated sun energy. Odds are that if it worked then it would of had extensive use throughout history, and we havent heard much about it anymore than a myth or legend. I'm sure Archimedes at least tested his idea using a small mirror array on some models and probably for some solar cooking and melting of objects.
@GREENPOWERSCIENCE Now you just have to get a real boat to not move up and down with the waves and to stay a fixed distance from the mirrors for an hour or so and you have a working weapon... Myth Busted :)
it could work but come on if you wanted to kill the enimy there were better options at the time... not saying it wouldnt work but its very impractical..
because mythbuster was more accurate, the greek does not have such a flawless mirror, they have bronze shield and that didn't relect to well, back in the days they used people instead of stuff... also trygetting 50 people to cordinate on hitting 1 ship amoungst the other 50 or so ships.
so yes it is possible, but mythbusters proved it wasn't back in the days of greek
Mythbusters is probably about the most scientific show that the mainstream will watch. As well as being an informative show, it helps the overwhelmingly scientifically illiterate masses get a bit of education. Such is a feat that should be applauded.
@Paradox3121 we must be talking about a different show, because the ones i see get it wrong a lot, or dont do the experiments correctly. That is not good for science or the masses. I'll do my own experiments the same as dan. Not worth relying on what the masses think anyway. Most is utter crap.
Can you think of one that is worth really worth watching for the sake of humanity or education.
@surfjacobson1 this wouldn't work in real life... boats tend to not stay in one place and move up, down, and in a direction... also, how are you gonna get 20 feet away from a boat and not have people on the other boat trow stuff to break the mirrors...
@andruha11234 - The point of the Mythbusters version is to demonstrate that while it WAS possible to concentrate solar rays enough to burn wood, it was not effective as a weapon because the target needs to (a) stand still for a long time, and (b) stay vulnerable for a long enough time that the solar concentrator can burn it sufficiently to take it out of the fight.
On surface-area physics alone, this video confirms it's OK for starting a campfire but useless for burning giant Roman ships.
How much damage you think instantaneous 400f would do to the enemy sailors/soldiers eyes?
Eyes are soft, vulnerable target which is both temporarily and permanently damaged easily. You don't need to burn down the ship to disable the enemy army. You just need to scorch a decent number of warriors eyes and face. Then they are useless.
@woodburyadpost they did do a good job. in this video they were pretty close to the target... and i doubt you be able to get that close to an enemy ship without them destroying your set up
@GREENPOWERSCIENCE If I were Archimedes, I would have shrouded my Incinerate-O-Ray Mirrors to look like... well, not highly specialized Incinerate-O-Ray Mirrors. If word ever spread to opposing forces; they would be on a wild goose chase... or "shield chase" wondering why their shields weren't awesome. Archimedes was very intelligent. I don't think it would be too charitable to assume he would have that kind of forethought, and may be the reason why we still don't know exactly how he did this.
That was the legend. He could have found the approximate focal length of a more or less standard shields, or even had each soldier's shield sighted in, and then each soldier positioned around the target site accordingly. They surely had some spot picked out where a ship would anchor. Mirror drills for precision targeting!
Imagine the grumbling as these soldiers were ordered to do that amount of bronze(?) polishing!
this is fake, archimedes' death ray didnt burn down the boats, they blended them so they crashed gf

The only way you can get a lot of them is through grapevine of friends for free.There is a lot of broken rear view mirrors being discarded everywhere. Why ?? Why didi the autowreckers discard broken rear view mirrors and keep good used ones for sale?? Why give to the recyclers for remelting . The broken rear view mirrors still has useful ball sockets that is critical !

Get a glass cutter and cut mirrors into 500 or more smaller squares maybe one inch or two inch and assemble them all on a special constructed board with adjusting screws or ram mounts (ball socket) for each tiny mirror so you can have a powerful smaller portable death ray board. What is more , you can make more copies of them . See what 10 death ray boards can do to a target. You can probably burn a 2000-3000 degree F hole through a steel plate one quarter inch thick . I saw them.

@dwarf2
Fire is one of the most dreaded dangers at sea. It always has been. Everything is so dry, and it spreads so fast.
If they set fire to the sail, the ship has a problem: it can't move, and is a sitting duck. If the sailors drop the sail, they're a sitting duck. If they wet the sail, they might be okay, but can they wet the top of the sail?
If the beam is focused on inside the boat, and in response they fill the boat with water, they go pretty slowly...

You always have such interesting videos. I think MIT and Myth Busters tried this and although MIT found it to be potentially feasible, it was highly impractical for a moving target.

Great video. One question. A mirror does not reflect 100% of the light that strikes it (disclaimer: I can not state this as a fact.) Did you consider this or care to comment on this?
Bob06460 1 year ago
@Bob06460 The glass absorbs some of the light, that is why first surface metal mentioned at 2:10 closes the gap between mirrors Archimedes may have used vs glass mirrors used in many recent tests. Most glass mirrors are 90% or less reflective depending on glass used and thickness. I shot a section explaining how glass mirrors are made but the video was getting too long.

This would not require a high levels of Sun and be only needed for very, very short times. Try shining a torch in your eyes, from a distance, and the switching it off... It takes quite a while for th eyes to readjust before you can see anything. Time for Archimedes side, to take other actions.

Of course the reason this weapon didn't expand everywhere was it's dependance on the right sunshine. One thing though was when this is tested it is important to the testers it destroys or starts fires. Not so. I would think the sailors would have got out of Dodge as soon as the heat started cooking hem like baked chicken. That;s why the NWO has microwave crowd control machines like this one; search, HEAT-RAY CROWD-BUSTER on youtube

I think the movement of the ships would have presented a lot of difficulties. If they were becalmed it could have been made to work. Does that sort of weather pattern happen in and near Syracuse though? Also they probably would have focused on the sales since they would have been much easier targets to hit and equally easy to ignite.

Awesome display of sun power. Although I doubt Archimedes heat ray would have worked. Not because he didn't have the skills or know how, but because the ships are constantly moving on the water. It would have been near impossible to hold a concentrated beam of light on a small area, much less the amount of beams needed to ignite it. I'm not saying it's impossible. I'm saying it's unlikely. Nice video :)

Im sure its possible. You got to know that Archimedes had probably hundreds of soldiers to help, so if Dan and Denise alone with fev mirrors burned small woden ship even in few hours. Im sure that hundreds of soldiers could burn more than one roman ship in fev minutes. Fire spreads fast and if it grow bigger than spreads faster. About mirrors im sure that it was possible to make them efficient enough. People in those time wosnt less smart they had only less knowledge.
SmokeTatum 1 year ago
This video shows that mirrors and sun light can be used as weapons against ships. They also show the weakness of the weapon - it only works during the day with a cloudless sky and at short range. At short range the soldiers would climb out of the ships and stab you. These practical limitations means that such a weapon would only get used once.

Archimedes was a bright guy. He invented a hook on a swing arm to hook enemy ships as they try to dock that would simply pull one side of the ship up until the lower side swamped and sank the ship. He also invented a long screw water pump, they used to pumped the water to tanks above the docks. In an emergency, these tanks were designed so they could be turned over to swamp ships trying to attack the docks.

I remember an episode of "Survivor Man" where he said that to aim a reflection toward something like a plane, for the purposes of signaling it, you should hold your hand out in front of you with a "peace" sign and shine the light between your fingers with the plane or object in the distance between your fingers too. I'm sure a group of soldiers could do the same thing or even build a scope on their mirrors back in the day.

I seen in another video where it cant be explained how an ancient wall/fort made of granite was partially melted, some think it was concentrated sun energy. Odds are that if it worked then it would of had extensive use throughout history, and we havent heard much about it anymore than a myth or legend. I'm sure Archimedes at least tested his idea using a small mirror array on some models and probably for some solar cooking and melting of objects.

joelito101 1 year ago
@andruha11234 - The point of the Mythbusters version is to demonstrate that while it WAS possible to concentrate solar rays enough to burn wood, it was not effective as a weapon because the target needs to (a) stand still for a long time, and (b) stay vulnerable for a long enough time that the solar concentrator can burn it sufficiently to take it out of the fight.
On surface-area physics alone, this video confirms it's OK for starting a campfire but useless for burning giant Roman ships.

@crimsonhalo13
How much damage you think instantaneous 400f would do to the enemy sailors/soldiers eyes?
Eyes are soft, vulnerable target which is both temporarily and permanently damaged easily. You don't need to burn down the ship to disable the enemy army. You just need to scorch a decent number of warriors eyes and face. Then they are useless.

I don't think it would be too charitable to assume he would have that kind of forethought, and may be the reason why we still don't know exactly how he did this.

That was the legend.

They surely had some spot picked out where a ship would anchor. Mirror drills for precision targeting!
Imagine the grumbling as these soldiers were ordered to do that amount of bronze(?) polishing!
