Hi. Today we're going to look another home made video about a Solar Death Ray, well at least that is what the man inside this video calls it. First, we look at the video.
Okay, first after you watched this clip, go to youtube and see the comments below. Most of the "nerds" there feel thrilled about this video and some claimed that this one is a fake. For what its worth, i think the idea is there. The concept is simple, by using the reflected light from the mirror to focus the sunlight on one point. I think the part where he burned down the wood in an instant is fake (i don't think it is in an instant but rather a few minutes) but if we focus the heat from the sun to one point, anything can burned up.
That's just the concept. To create it on the other hand, need a level of detail where you need to concentrate your focus and can't be distracted. The mirror must properly aligned so that the focus point created is small and i think the smaller the focus point, the higher the heat energy that is focused on that point. Well, you can try to create it. What you need is a parabolic dish. An advice from a fellow youtube commenter, he said create a model using the software (he didn't state which one) to determine the focus point, amount of mirror needed, size of the mirror and how to align the mirror to give the smallest focus point available.
"Hellas is the name for Greece. The name Hellas stands; 'land of light' or illumination. Thus here is its weapon the sun's rays, that the Hellenes used as their weapon!" by aek1928 - A comment from youtube.
p/s: if anyone can create a smaller hand held solar death ray, than i'd love to buy it from you. XD
