After processing you're still left with tons of gaseous He3 that you might want to transport to Earth, in the example 40 tons of it. To transport it you would liquefy it at nearly zero degrees Kelvin and you would then have to store it into dewar flasks to keep it cold.Process it on the moon with He3 processing plant before shipping it back to Earth.
Perhaps you would do better to generate the energy on the Moon and send it as radio waves to antennae parks in the Gobi desert and the Sahara being careful not to boil overflying birds.
