Student Recreates the Archimedes Death Ray

Click For Summary

Discussion Overview

The discussion centers around the recreation of the Archimedes Death Ray, a historical concept involving the use of mirrors to focus sunlight to ignite enemy ships. Participants explore the feasibility of this idea through various experiments and historical references, including recent attempts by students and previous tests conducted by shows like Mythbusters.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants mention a recent student experiment that successfully recreated the Archimedes Death Ray using mirrors to test temperature increases.
  • Others point out that an architect had previously achieved similar results years before the student, suggesting a history of attempts to recreate the concept.
  • One participant references a Disney building that utilized curved glass to raise temperatures in nearby structures, indicating practical applications of similar principles.
  • Mythbusters is cited as having tested the concept, concluding that the Death Ray would not have worked effectively due to ignition time and wood moisture content.
  • A participant recalls an earlier Usenet post by Henry Spencer discussing a potential recreation, possibly referring to Ioannis Sakkas's experiment in 1973, and mentions MIT professor David Wallace's later tests suggesting some feasibility.
  • There is a humorous exchange about the aircraft depicted in a related image, with conflicting identifications of the plane type.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and historical context of the Archimedes Death Ray, with no consensus reached on its effectiveness or the validity of various claims regarding prior experiments.

Contextual Notes

Limitations include the lack of definitive evidence supporting the effectiveness of the Death Ray, varying interpretations of historical experiments, and the dependence on specific conditions for the proposed methods to work.

Who May Find This Useful

Readers interested in historical experiments, the intersection of science and engineering, and discussions on the feasibility of ancient technologies may find this thread engaging.

Um, that looks an awful lot like a B-25 bomber aircraft flying above those primitive warships from 213BC...

An architect beat the student to this achievement by several years.

There was one Disney building even earlier in California in 2003 where a building's curved glass raised the temperature of nearby buildings by many degrees:



Mythbusters also had an episode on it that said it couldn't have worked well due to the length of time needed for ignition and the increased moisture content of boat wood.

I think the first successful attempt I heard of to recrate this was in an old Usenet post by Henry Spencer but it had no reference. I think he could have been referring to an experiment by Ioannis Sakkas in 1973. When the Mythbusters failed MIT professor David Wallace and some students did a test that suggested it was at least somewhat feasible.

Nah, that is a Heinkel-111.

Spoiler for a 2023 movie.
The image is from the latest Indiana Jones movie.

I fought the Ray and the Ray won.

Closing this thread so we'll be done.
