Bought this book a few years back and it has grown heavy on my mind. Been reading it for about a week now off and on up in the mountains. Home now with about 7 or 8 inches of snow on the ground. But thought I would share this.

One paragraph mentioned having a pair of gyroscopes that created a field of negative gravity. It seemed interesting.
