The Sky Maniac by Henri Dahl Juve:
Science Fiction Inventions, Technology and Ideas

"You have of course read “The Silent Destroyer.” Now the same author comes forward with a sequel to that story. The present effort is every hit as interesting and every bit as absorbing as the first story, and in addition to it, it contains that rare gem, an "O. Henry-like” ending that cannot fail to charm you.


('The Sky Maniac' by Henrik Dahl Juve)

As civilization advances humanity tends to throw off things which our ancestors learned with difficulty. Yet some of these things come in very handy at times. Thus for instance, if you were suddenly marooned on a strange island and had no matches or other means to make a fire, the knowledge of how to make it by rotating a wooden stick and another piece of wood, would come in most handy. Always providing of course, you knew what woods to use, which most of us don’t.

“Lost arts” are always interesting and students should not lose sight of them, because one never knows when they may prove valuable." Select an invention:

Diagnostic Type Sense Transmitter
Allows the doctor to directly feel the same sensations that the patient feels.

Gravity Nullifier
Shields a large object from the effect of gravity.

Pocket Gravity Nullifier
Personal device stops gravity's effect.
