[custom_adv] Dynasphere The Dynasphere was a single-wheeled vehicle invented in 1930 by John Archibald Purves.

[custom_adv] Ford Soybean Car Henry Ford was so interested in using plants, especially soybeans, in motor vehicle production that he built a laboratory dedicated to soybean research. At first, he used soybeans to make parts for his cars, but then he decided to make an entire car out of soybeans. Although the car did have a steel frame, it was covered with plastic that was made from a mixture of soybeans, wheat, hemp, and other plants. [custom_adv] Tucker Car Famously called the “Tucker Torpedo,” the Tucker car was made just after World War II by policeman-turned-carmaker Preston Tucker.

[custom_adv] Prop Cars Several propeller-driven cars were made in the 20th century, but none entered mass production due to safety concerns.

[custom_adv] Dymaxion Car The Dymaxion Car was a three-wheel, 11-seat flying car made by Buckminster Fuller in 1933. Its name was a combination of the words “dynamic,” “maximum,” and “ion.” The Dymaxion Car was shaped like a zeppelin and had wings that automatically inflated, causing the vehicle to go airborne at full speed. However, it proved highly impractical because it was difficult to control while airborne. [custom_adv] Pininfarina X The Pininfarina X (code-named “Pf-X”) was one of the earliest aerodynamic cars ever made. Although Batista “Pinin” Farina often gets credit for designing this car, several other notable people took part in its development.
