3He

China looks to the moon for energy

What are they after? A limitless source of clean, safe energy to feed their voracious economy. The stable isotope helium 3 (3He), a potential fuel for nuclear fusion, was first found in moon rocks brought back by the Apollo missions. It is one constituent of the "solar wind" constantly given off by the Sun. The stuff bounces off Earth's magnetic field, but the moon has no magnetic field, and its surface has been soaking up 3He for billions of years. If you could dig it up and put it into a fusion reactor you would get ordinary helium 4 (as in balloons), ordinary hydrogen (as in H2O) and an abundance of radioactivity-free energy. According to Gerald Kulcinski, director of the Fusion Technology Institute at the University of Wisconsin at Madison, a mere 40 tons would be roughly enough to serve America's electrical needs for a year.

This reminds me of those games where you send out your peons to mine for gold so you can build a city. The whole point in those games is to control the resources... When are we going to start having wars over the moon?
