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. Space Colonies by Don Davis Sport in Space Colonies
