Brenden Sener of Ontario won multiple medals for his miniature version of the Archimedes death ray, crafted with light and mirrors. No archaeological evidence exists that proves the death ray was ever employed, but Sener believes it very well could have been. Archimedes wrote about harnessing the Sun’s energy to create a death ray. In his view, he as shown that “the principle behind the Archimedes Death Ray is certainly possible,” according to his 2024 paper published in the Canadian Science Fair Journal. Sener believes that all the testing continues to add up to plausibility.
