It’s unclear why this was; certainly inventors were copying an existing mode of transportation, but why would they draw inspiration only from the horse-and-carriage, and not from the... See more

A ship’s propeller doesn’t move the same way a fish’s tail fin does - it replaces the back and forth movement of the tail with a simple rotation that... See more

Rural areas—where commutes are long and interruptive skyscrapers are scarce—are the more likely initial setting for airborne technology. Once drones and flying cars prove out in Idaho, perhaps they will migrate to Manhattan. Or not. Flying cars might ultimately be the rare Davos dream... See more
