Why did you use the yellow wire as leads? Is it a different gauge? Also, diodes require very little energy. Please show a multimeter reading. Can you present any computation?
Nice music (name?), but you dont get electric charge without movement. I assume there is inductive current coming from under the table or something along those lines. Either way there is *some* external power source to this, otherwise we would have a perpetuum mobile, which is sadly impossible.
