Living Off the Land in Space Green Roads to the Cosmos

From the reviews:

"The goal of the book is to provide a realistic view of what might be possible with technologies that are accessible in the near future. A wealth of references at the end of each chapter point the way to further resources.

"This book is … about ways of powering spaceships to get to other worlds. … the book explores ways of accelerating spaceships using the environments encountered on the journey through space. … The book discusses other means of powering spacecraft, including gravity assists from planetary flybys, ion drives, solar sailing and electromagnetic tethers. … Overall the book is more a review of current or developing techniques … . I found it an enjoyable read and informative." (P L Dyson, Australian Physics, Vol. 45 (1), 2008)

The book is written by a pair of scientists … ." (Claude Semay, Physicalia, Vol. 30 (2), 2008)
