Imagine a spaceship 135 feet in diameter, and 10 stories tall. Imagine it weighing 4000 tons. Bet that doesn't sound too impressive. If this were a normal chemical rocket, only about 10 tons of this would make it into space. Now just imagine for a moment that there was a way to allow over 3500 tons of this ship to make it to orbit. This is possible, if a ship were to launch nuclear bombs as fuel. This is known as Project Orion.
George Dyson's new book is the source for information on Project Orion. Unless you are willing to undergo extensive primary research, a total of 6000 pages worth, or you have connections among the staff of the former Project Orion staff, then you can't find a better source.
The book starts with the Day Sputnik was launched. This was an inspiration to a great many Americans, not the least of whom was Ted Taylor. From that day onward, Ted became fascinated with finding a way to build a space ship of his own. This path would lead him to probably the most controversial design for a spacecraft ever, and probably one of the greatest "What If" statements of all time, his path led him to Project Orion.
George Dyson does a great job of bringing the key points of the history of Project Orion together in one place. He covers virtually ever aspect, including nearly a dozen different designs for Orion, information on it's design to the best degree publicly available, and interviews with most of the living former Orion staff. He also covers many of the potential problems, including the shock absorbers, fallout, and many more.
I would recommend this book to anyone who has looked at the stars and wanted to be there. It is also great for people who want to study physics, anything nuclear, space travel, or even a bureaucracy. But perhaps most of all, I recommend this book to any who have ever wondered "What if".
