According to CNN, this was an idea first proposed by Archimedes. But now, “Brenden Senner, 13, of London, Ont., is using a tiny version of the alleged war weapon, which consists of a number of mirrors designed to focus and aim. According to a paper published in the January issue of the Canadian Science Fair Journal, which won two gold medals and a London Public Library Award, sunlight hitting a target such as a ship causes it to burn.
For his 2022 science project, Senner recreated Archimedes' screw, a device used to raise and move water. But he didn't stop there. Mr. Senner found the death ray to be one of the most interesting devices he had ever seen. This is also called a hot wire. Historical documents say that Archimedes used a “flaming mirror” to set a moored ship on fire during his siege of Syracuse from 214 BC to his 212 AD.
As Senner pointed out in his paper, there is no archaeological evidence that this device ever existed, but many people have attempted to recreate the mechanism to see if the ancient invention was viable. Ta. In Mr. Zenner's beam experiment, he set up a heat lamp facing his four small concave mirrors and tilted them so that each focused the light on a piece of cardboard with his X mark on it. In the project, which he designed for the 2023 Matthews His Hall Annual Science Fair, Senner hypothesized that as the mirrors concentrate light energy onto the cardboard, the temperature of the target would increase with each additional mirror. I did.
In his experiment, Senner conducted three tests using two different bulb wattages: 50 watts and 100 watts. He found that each time he added a mirror, the temperature rose significantly…With only a heat lamp and he a 100 watt light bulb, the temperature of the cardboard without the mirror was about 81 degrees (27.2 degrees Celsius) was. After waiting for the cardboard to cool, Senner added his own mirror and retested. He found that the temperature of the focus rose to nearly 95°F (34.9°C). The largest increase occurred with the addition of a fourth mirror. The temperature of his three mirrors as he aimed at the target was almost 110 F (43.4 C), but when he added the fourth mirror the temperature increased by about 18 F (10 C) and he dropped to 128 F (53.5 C). )became…
Senner said he wasn't trying to set anything on fire because “heat lamps don't produce enough heat like the sun.” But with sunlight and a larger mirror, he believes “the temperature would rise even more rapidly and at a faster rate” and “could easily cause combustion.”
Senner's paper notes that this powerful weapon would not work on cloudy days and could be less effective even when the ship was moving.
But Senner said in an interview with CNN that Archimedes' death ray was a “great idea.”
