Screw-Ship (May, 1939)

Tomorrows Inventions

PLANS for a speedy submarine “screw-ship,” which would serve as a carrier for the quick dispatch of mail and freight between continents, have been developed by Maximilian Bernd, an engineer in Hamburg, Germany. Resembling a torpedo in general appearance, the proposed underwater craft consists of two parts. One, a cylinder-like inner chamber, features the crew’s rooms, the storage hold, engines (electric) and a gyro device to maintain balance. The other part of the future “screw-ship” consists of a steel outer jacket which rotates around the stationary inner chamber by means of a special gear and bearing arrangement and which has spiral-shaped metal fins fastened to its surface. When the engines cause the outer jacket to rotate, the spiral fins screw into the water much as the threads of a screw bite into wood, thus forcing the craft forward. A periscope at the nose and a rudder at the rear facilitate steering.

    Hey sailor, wasn’t “Screw-Ship” the original name for the Village People’s “In the Navy”?

    The screw ship famously torpedoed Gary Hart’s presidential campaign in 1984.

    Aha! Now we’re talking! Forget that silly turbo-disc ship from the other day, this one’s gonna work. For sure.

    Wait a minute:

    “…steel outer jacket which rotates around the stationary inner chamber by means of a special gear and bearing arrangement”

    So what happens when that bearing fails? Round and round we goooooo….
