THE FUTURE:
Is the high speed freeway obsolete? What effects will rapid
transit have on our urban centers? How will space technology change
our concepts of travel? What are the alternatives in terms of fuels?
Will the helicopter become a common family vehicle? What is the
potential of the air-cushion vehicle? What are the substitutes for
the automobile? Can we produce alcohol from wood or corn in quantities
to replace oil?
