In February 1855, Emerson wrote in his journal, under the heading "Common Fame": If a man has good corn or wood, or boards, or pigs, to sell, or can make better chairs or knives, crucibles or church organs, than anybody else, you will find a broad hard-beaten road to his house, though it be in the woods.

A concept car (also known as a concept vehicle or show vehicle) is a car made to showcase new styling or new technology. Concept cars are often exhibited at motor shows to gauge customer reaction to new and radical designs which may or may not be produced .
The machine is powered by two symmetric springs hidden in drum-like casings. While one spring would be enough to move the device, two symmetric springs probably looked like a more "logically perfect" solution. Leonardo had been well aware that the powering force provided by the springs drops significantly when they unwind.
Inspiration is a British-designed and -built steam-propelled car designed by Glynne Bowsher and developed by the British Steam Car Challenge team.
