Will you believe it; you actually can vaporize wood and even melt down the steel, by only focusing sunlight with mirrors? It sounds crazy to be true, but a few geniuses MIT students have successfully prove themselves and transform this idea into a reality. The main objective for this project is based on super-efficiency solar energy and environmental friendly concept. The steel-melting solar mirror is a 12-foot by 12-foot parabolic mirror, or you’re also can considered it as a solar concentrator; that is primarily made from the off-the-shelf metal framing which fitted the bent mirrors to enable the sunlight to be focused in a single point.
SIGGRAPH is a marvelous creation, thanks to the genius team from University of Southern California. Although the cost for this project is low, but SIGGRAPH can offers several advantages of displaying 3D objects in 3D. The characteristic for this display is: Autostereoscopic: no need any kinds of viewing glasses Omnidirectional: constantly generates simultaneous views Interactive: can easily update the content at 200Hz According to the spokesperson, this SIGGRPAH works by simply projecting a high-speed video onto a fast speed spinning mirror. While the mirror turning, it will reflects different and high accuracy image to every viewer. With the help of rendering algorithm, it also can rebuild both virtual and real scene, either with correct occlusion, horizontal, vertical perspective and even shading as well! We have to know that the flat surfaces represent only a small part of the real physical world, while we all standing still in a three-dimensional award platform. The team next big project is to create a new generation of display, which will begin to represent the physical world. We are waiting for this day to come. [source]
