The Louisiana Purchase stretched from the Mississippi River to the beginning of the Rocky Mountains. Official boundaries were not determined, except that the eastern border ran from the source of the Mississippi River north to the 31 degrees north.
Cooled (or air conditioned) seats work by confining cooled air directly in the seat where the passenger is seated. Multiple fans are put within the seat to provide air circulation. The air from the fans blows through a diffusion layer to spread the cool air throughout the seating material, cooling the whole surface.
Heated/Ventilated Seats. Heated seats use a heating mechanism built inside of the seat to create a warm area on your legs, thighs, and back. Ventilated seats offer air through the seat to cool the passenger down. Heated and ventilated seats make the ride more comfortable because they can be individually controlled to the passengerâs liking.
