		So who's heard about the new wonder material, grapheme? I just read an article that it would be the perfect material for speaker diaphragms, which need to be thin but strong. It's just one atom of carbon thick, but 300 times stronger than steel! It's so thin that they are calling it two dimensional. And it has a great dynamic range, because it's also not brittle.
