On the <strong>Moon</strong>, once there are two settlements of rival size, interdependent traffic between them will be<br />
relatively strong no matter how far apart they are (3,392 miles max, one half lunar circumference.) And there will be<br />
no real alternative, aviation being out of consideration.<br />
NOT FOR EVERYWHERE & NOT SOON<br />
The Interchute is a much more specialized <strong>transportation</strong> system than are railroads. Nor would realization of<br />
this dream be a down payment on “general aviation” in any sort of<br />
form realizable on the <strong>Moon</strong>:<br />
1. Interchute loops, of whatever length and frequency of use, will require a very large capital investment.<br />
2. The further two potential terminals are apart in terms of real alternative road travel time, the greater the time<br />
savings and the stronger the incentive to build an Interchute.<br />
3. Towns a few hours apart by good highway would not be good candidates no matter how much mutual traffic they<br />
generated. High speed rail (see MM Review #13, AUG 13, pp. 9-15 “Lunar Railroads”) or Maglev would be the Choice.<br />

Interchutes will be a travel option on the <strong>Moon</strong> some generations down the road, when and if the lunar<br />
frontier economy fully develops to its full potential, which is considerable. <br />

Note: NASA has since met this concept “halfway”<br />
By reducing the structure lifting off the <strong>Moon</strong>, and hence minimizing its mass, to the Lunar Lander “airlock”<br />
and by thus minimizing the mass returning from the <strong>Moon</strong>’s surface, the amount of mass and structure that can be<br />
left on the <strong>Moon</strong> is increased by that same amount.<br />
