"<strong>9. ""IMPROVEMENT IN VEHICLES""  </strong> If cow power isn't your thing, go to the dogs. In 1875, Parisian inventor Narcisse Hueet patented the ""cynophere,"" a dog-powered velocipede. Hueet wrote, ""My invention contemplates the employment of dogs or other animals, working within a cage or cages, forming part of the wheels of the vehicle to be propelled,"" Strangely, the French Society for the Prevention of Cruelty to Animals gave his invention a thumbs up."
