There are two interesting and remarkable techno-military suggests in this October, 1916 issue of Popular Mechanics. First is the cover story, a ("destroyer") aircraft bomber is to be launched from a "battleship" aircraft for a one-two punch of carpet and strategic bombing. The large "mother ship" was to have a 143' wingspan, making it a monster of a plane for the time. It would enough fuel and oil to keep it aloft for 48 hours, and also have a 1000-pound payload "of bombs", and a crew of five, two of whom would be wingwalkers firing machine guns. And another plane. The smaller aircraft was "equipped with bomb-dropping devices" and was to be launched for a special raid and/or to ward off enemy attack planes. But the fly in the ointment, says the article, was getting the smaller aircraft back to the larger one--launching was no problem; landing was. And I can see why.
The second article in the issue--the so-called underwater lighthouse (appearing under the far less amusing but much more informative title of "Mine Control Protects Neutral Shipping")--was a defensive and offensive buoy-structure that would provide a very claustrophobically-unwantable job for someone. The buoy was made to control an undisclosed-number field of mines in/near shipping lanes and differentiate friendly from unfriendly ships.
The buoy would have an observation area from which our unlucky guardian would scan the seas; once a ship was spotted, the buoy would submerge to periscope depth, and after some time the nationality of the ship would be identified; at that point if an enemy ship is recognized the operator could submerge the buoy further (being anchored to the sea floor) via a winch to 50 or 60 feet beneath the surface, and then when the mine made contact (proximity or otherwise?) the buoy operator could detonate the mine. It was thought in this way that you could mine an area of sea and not have to worry about ships being damaged by friendly fire. The whole thing seems highly problematic to me--not the least of which would probably be a very jostling ride to the buoy operator.
And so two adventures in speculative military technology in one single war-time issue of Popular Mechanics.
