[edit] Mythbusters prove that the mirror weapon was a myth
(the tale of mirrors to reflect light onto the Roman fleet intended to cause fires was actually a myth introduced several centuries later by various historians.) *This myth was tested on the show MythBusters, and proved that mirrors to light fires were not only impractical but virutally impossible for the following reasons: 1. Worked only at a short distance (less than 50 meters) 2. Worked only on stationary targets (Roman ships, however, moved) 3. Took too long to light an object on fire (more than 15 minutes), and most of the trials failed 4. Could not coordinate all the mirrors to focus on one single ship 5. Huge amount of mirrors required

Thats very intersesting i wish i had caught the show i often wondered about hows the mirrors would work thanks for letting me know. user:king Alaric
It was an interesting show but the mirrors used by Mythbusters were rather primitive.
In 1747 George Louis LeClerc experimented to find if the burning ships myth was possible. He assembled 168 8x10 inch mirrors adjusted for a focal lenth of 150 ft. He then removed mirrors to find the minimum needed to set fire to a target. It took 128 mirrors to ignite instantly a pine plank at 150 feet. 40 mirrors would ignite a plank coated in Creosote at 66 feet.
Then in 1976 Dr Ioannis Sakkis used 60 sailors each holding an oblong mirror to "instantly" ignite a ship at 160 feet. The ship was not moving and the sailors couldn't keep focus on one that was.
In 1992 a physics experiment tried to replicate what was possible in the siege. The scientists found they needed 440 men each with a bronze mirror 3 ft sq to ignite a ship at 150 feet. They concluded it was possible but a waste of manpower.
The most common reason for debunking the myth is that it is so hard to ignite a moving ship but there are records that claim that Archimedes first immobilised the ships with an "iron hand" then set them on fire so it's possible he used relatively few men at a much shorter distance than claimed.

OK thanks for the advise ive put a small section in about the possibility of mirrors user: king alaric
