Ever notice how some things just suddenly become part of the zeitgeist? Like Palin, of late, Helium 3 has been making the news - expect more in future. India has just started its own space race to the moon. It turns out the rare isotope Helium 3 (scientists, correct me if I am wrong) is less rare on the moon than here on terra firm, and can be used in sec-gen fusion reactions to generate extraordinary amounts of energy. Moon-mining may soon leap back into our lives, and off the ragged pages of Asimov's mouldering paperbacks.
