A voyage of the imagination into the future on and outside our planet by Nigel Calder

The most fully developed plan for living permanently in Space has been created by Professor Gerard O'Neill of Princeton University. Round O'Neill's scheme is a complex of new technology devised by scientists and engineers who believe families could be living in Space before the end of the century and providing Earth with power and minerals as well. Biologists and psychologists including Professor Edward Wilson of Harvard, and Professor Richard Gregory, of Bristol, consider the human needs of an orbiting population, and other scientists sum up the costs and benefits of the vast adventure into Space.
