Melt Those Pennies
Newer pennies use more zinc and have reduced quantities of copper. However, somebody has pointed out that zinc now costs more as well. I've seen another estimate saying that melting down both the copper and the zinc in today's pennies could yield you as much as 1.6 cents per penny.
This gets us thinking: What about all that twisted pair? If only there was an easy to recycle the stuff, the telcos might have a way to have their old networks pay for new fiber.
