How To Travel To and Explore Mars or Proxima Centauri B (Paperback) (ISBN-13: 9781088501719)

Use of fuel is impractical for space exploration. The only fuel-free acceleration for space exploration is by controlled gravitation, and that is the only means for a flying vehicle to explore a distant planet and the only means of travel to it. Such control of gravitation is the subject and purpose of this book. Just as the sail-driven ships of past centuries explored the world with fuel-free travel by controlled use of the wind; a new gravitation technology will enable fuel-free exploration of space by control of the ubiquitous gravitational field.
