15 Old Inventions Even We Can Tell Were Never Going to Work
Inventors have always had a talent for solving problems nobody else noticed, usually with a questionable number of wheels, straps, or propellers. Some creations were genuinely clever, at least until someone tried using them. Others required an extraordinary amount of confidence just to climb aboard. The early days of transportation were particularly ambitious, but strange ideas also found their way into beauty products, household gadgets, and entertainment. A few of these inventions actually worked, although not well enough to become everyday essentials. Others were based on promises that simply couldn’t be delivered. Here are 15 old inventions that probably should have stayed on the drawing board.

A Motorcycle Inside a Giant Wheel

An 1899 illustration depicts Jacques de Vaucanson’s mechanical duck, a famous 18th-century automaton that supposedly ate and digested food.

A Car That Went Swimming
The Amphicar promised drivers a vehicle that could travel on roads and across water, although fewer than 4,000 were produced.

Taking Your Bicycle Swimming
An 1894 illustration shows a water bicycle supported by large airtight wheels fitted with paddles, allowing its rider to pedal across the surface.

Television Through a Tiny Window
A woman watches an experimental mechanical television in 1928, peering into a viewing cone that displayed an image only about 1.5 inches wide.

The Personal Rocket Backpack
A 1962 demonstration shows the Bell Rocket Belt carrying a pilot into the air, although the device’s extremely limited flight time made everyday use impractical.

The Car That Didn’t Look Like a Car
Buckminster Fuller’s 1933 Dymaxion car featured three wheels, a streamlined body, and rear-wheel steering, but only three prototypes were ever built.
