The fax machine at the office* has been working overtime spitting-out un-solicited "Stock market news letters" . You know the ones ,penny stock crap.
A lot are unknown energy technology companies with "Breakthrough" technology that want you to "Get in on the ground floor". It's getting kind of deep with $70 oil.
IIRC ,* about 15 or 20 years ago, a "Cold Fusion" breakthrough by 2 research grad's at univ. of ?* * * *Big deal and lot's of news media.

I find these faxes quite usefull , along with junk mail. It helps us meet our paper recycle quota for the office.
