DEMOLITION. The deeper an explosive, atomic or chemical, is buried under the surface, the more of its energy it imparts, to a shock wave passing through the earth; hence, atomic demolition bombs would offer an effective method of destroying deep dugouts, shelters or underground factories...
Instead of transmitting on direct line-of-sight, the Bell-M.I.T. method shoots a beam into the sky like a giant searchlight. A searchlight beam passing through the air is visible many miles away although the light itself may be behind a hill. A microwave beam can be "seen" in much the same way. If it is very powerful...
...greater (10,000 watts instead of half a watt), and the antennae must be great parabolic "dishes" 60 ft. in diameter. But long-jump has uses that are vitally important in military communication, where construction of short-range relay stations is impossible or impractical. For example the long-jump method could be used across the water gaps and wilderness stretches of arctic Canada, where it would make sense to relay to a rear headquarters the pictures picked up by the far-flung radar outposts. There have been hints that a part of this system is already installed...
...guidance, it loses touch with its control station as soon as it passes out of "sight" beyond the curve of the earth. It is possible that the new system can keep the missile firmly on a microwave leash over a far greater distance than the line-of-sight method permitted...

It contains improvements on many traditional experiments and includes new ones. The book is the first to contain provisions for his new efficiency method...
