LU input devices on the Glowing Ring which is black and seems like glasses in the pic. Another thing you must understand is, this is NOT a magnetic confinement fusion videlicet Tokamak. Actually the magnetic confinement one walks behind the times since inertial confinement one was designed. The inertial confinement fusion use a “bit” of high powered laser to induce the fusion process. I cannot go any longer because I do not want to copy paragraphs from Wiki. Wiki will tell you more about fusion needed no magnet.
