Just like 'green' cars, the costs to the environment far exceed
traditional techniques.

As to magnets picking up fillings, neat trick since they are
non-magnetic: shows just how well thought out this bit of swill really
is!

Most metals are pretty good conductors, thus you can pick up most any
metal using electromagnets. Similar to how a squirrel cage motor works.

Have you ever actually tried this with, say, aluminum or stainless?
