You know the spam: the Nigerian oil minister has an outrageous sum of money and desperately needs a foreigner’s help to take it off his hands. But the times are changing — junk email has gone green! A New York Times blogger reports receiving an email asking for investment in a Renewable Energy Technology System. “Everyday, every month, every years, and infinite, every climate change and this RETS is always a stable energy,” promises the email. “This we can control the working of it and 100 percent for save and security in our planet. Now, the RETS have no patent for them, it is waiting you in this patent. We wish to protect the data and benefits together with you.” Now there’s an offer you can’t refuse. But do.
