Solar-powered laser (supposedly)
I was in this other forum about the Mythbusters' "Archimedes' Death Ray" thing. Our discussion went off topic, so I made another topic! According to Google, a laser is a device that produces monochromatic, coherent beam of light. We have established the coherent part of it by focusing the Sun's energy on point which has a mirror so theoretically, that focused part of the beam should reflect off the mirror. Our design(s) is/are based on multiple parabolas (or Fresnel lenses) to collect and focus light. The light is in turn reflected off mirrors to be combined on a mirror (or lens) which will be used to aim the light to the target. Unfortunately, I forgot the "monochromatic" part of the laser, but that's not a problem. All we have to do is put filters on our parabolas. That should be a cool enough part to filter the light without melting the filter(s) itself / themselves. What would be an idiotic thing to do is put the filter right in front of the last mirror, because it would melt it (unless off course, that filter was a pane of glass).
Any suggestions/comments/design ideas please put them up here. If your idea is just downright stupid (sorry, I don't know what else to use (other than idiotic, or crazy, actually crazy's better than stupid (back to topic))). If it is stupid, I will not use offensive words against you (unless you were swearing on my face); you will, instead, be facing the following words: "Sorry, your (insert suggestion/comment/idea) is not feasible. Please try again". I know it's a bit funny; part of it is for your entertainment, part of it is for your knowing. Again, please post any suggestion, comment, or ideas. By the way, if it's only a bit stupid, you won't be needing to face the words...
Have a nice day!
