it has come to my attention by people reading my material that the led i described was not creating antimatter the way it was supposed to, and the light saber was not deadly. more of a children’s toy.
i have worked out that (as suggested before) you may need to use another radioactive metal / metal combination.
it seems that a gram or less of plutonium possibly combined with another metal (iron maybe).
i have no way of trying it as i can not get my hands on a gram of plutonium to make the alloy for the led.
once the led is constructed you should be able to create antimatter with a flash of it, and also create a light saber out of it using the led, a lead case, and a glass to focus the beam. once again increased amperage will extend the length of the beam. increasing the voltage may possibly change the wavelength.
once again do not attempt to try my experiment unless you have a license for the materials, and the proper facility and education. just me thinking on the web. let me know if anyone can legally build them so i can see the cool effects.
