Predictions of the future can turn into embarrassing documents. Paleo-Future, a blog dedicated solely to unearthing past prognostications about, as its motto states, â€œthe future that never was," makes a living off such documents.

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.
