Info:

The Poochmobile, a bizarre yet earnest experiment in alternative transportation, was built in 1939 by 80-year-old Z. Wiggs, a dog trainer and former railroad worker from Denton, Texas.

The contraption featured a large central “squirrel-cage” wheel powered by a single dog walking inside it, transmitting motion via a belt-and-pulley system to the rear wheels.

Wiggs envisioned it as a fuel-free solution to modern transport—a Depression-era glimpse at “green” mobility. Despite its ingenuity, the Poochmobile was widely viewed as charmingly impractical and never made it past the prototype stage.
