Thank you for this post Bejak. I can't help but think, however, that your calculations would only work if the density of the insulation is the same as the density of the copper wire. Density being: The mass per unit volume of a substance under specified conditions. As in the case of the Christmas lights, in a comparison using an actual scale to measure pre-stripped vs. stripped Christmas light wire wouldn't you end up with closer to an 16-18% recovery rate and not the 30-35% you indicate via your metrics? Thanks again for opening this discussion.
