Duke is clearly passionate about his topic, but he is no engineer. His notion that a reactor and a lot of water will get you to nearly light speed is true, but he grossly under estimates the mass required to do it. The more mass the lower the acceleration and the more additional mass. It is the old specific impulse problem...ultimately the starship must be so huge it becomes impractical. While I like his enthusiasm, I think he needs to review a few good books on rocket propulsion concepts.

Although I think that mankind could reach the stars, it would take at least 2000 years at a tenth of the speed of light, which is about as fast as any vessel could travel. The author has extrapolated and distorted science to prove his thesis. Thus it is is one of the worst scientific books ever. No reputable scientist would even endorse any of his theories. Buy it only if you want a good laugh.

This book reminded me of the wisdom of planting a tree. Often, the planter will never see the benefits of the harvest.
Sending arks of starships to colonize Earth-like planets would be a great way for nations to contribute on an International Project that ensures the survival of the human race.
Dr. Duke's vision is both practical and forward thinking. Although we might never see the fruit of our labors, this is a risk all true explorers take. Using technology we already possess, we can become a spacefaring planet. Who knows what fruit might be harvested by future generations.
