A November 2, 1979 article by John Yemma in the Christian Science Monitor outlined Jesco Von Puttkamer's vision of America's future in space. Von Puttkamer was a planner for NASA and even consulted on the first Star Trek movie.

By the late '80s or early '90s, a huge solar power satellite may be constructed to beam microwave energy to Earth. And after that, a natural step as Mr. Von Puttkamer sees it, will be space colonies built with nonterrestial material and using solar energy.
