So, to lower air density in a balloon without losing air pressure, you simply need to increase the speed of the air particles. In addition, he says no other engine has a design with forced induction of compressed air entering the combustion chamber while at the same time air-cooling the top of the piston to lower emissions. That was understandable. The company had enjoyed record sales in 1929, and interest in both aviation and air-cooling was at an all-time high. Aviation Consumer Protection Division. At one time, Franklin was the world’s largest consumer of aluminum. Franklin’s commitment to “aircooling” got a boost when Charles A. Lindbergh made his historic transatlantic flight in 1927. After all, the Spirit of St. Louis had an air-cooled engine, and Franklin advertising eagerly pointed up the paral­lel. Franklin’s situation was now quite desperate. Over in Switzerland, there’s another carbon capture plant run by Climeworks, a separate company that now sells recycled CO2. This now had shutters governing the amount of incoming air, with shutter opening controlled automatically by a thermostat connected to the number-one cylinder. In an age when cast iron was the standard stuff of engine blocks, pistons, and cylinder heads, Franklin used high-grade, light-weight aluminum.

The Olympic was a very good car, but it was too late to save Franklin. By the standards of 1932, the Franklin Twelve was truly exotic and magnificent to the eye. The Twelve was originally planned for the 1931 DeLuxe Six chassis, but was delayed to ’32 by financial problems. Seeking desperately to maintain production levels, Franklin introduced the “Transcontinent Six” (Series 141) in May 1930. Like the “145,” it offered a closed coupe, convertible coupe, victoria brougham, and four-door sedan on the 125-inch chassis. Among the more memorable 1930 open styles was Dietrich’s four-door Pirate, available as either a five-passenger phaeton or seven-seater touring. Reflecting Franklin’s rosy outlook was its 1930 line of “145” and “147” models with new styling and power on respective wheelbases of 125 and 132 inches. Trouble was, the Great Depression had all but killed the “fine car business,” so Franklin’s 1930 ­calendar-year sales came to less than half its 1929 total. But sales were far from that: an estimated 200 for the model year, plus another 1700 or so six-cylinder Airmans on the 132-inch wheelbase chassis. On a 144-inch wheelbase chassis, its size alone was impressive.

Up in the $2400-$2700 area was the DeLuxe Six, a four-model group sporting rakish clamshell fenders and beautiful flowing body lines by Ray Dietrich on the 132-inch wheelbase. Just 1218 were built for 1933, and a mere 109 for swan-song 1934. Franklin also offered mechanically unchanged Twelves and Airman Sixes in those final two years, each with four body styles, but production was minuscule.

Pilots will use this speed to maximize endurance (minimum fuel consumption), or maximize gliding range in the event of an engine failure. This is why undercooked ground beef and unpasteurized milk consumption are frequently associated with E. coli epidemics. There are many different kinds of tires, too, from fuel-efficient small tires to big 24-inchers with flashy rims. But even the cheapest tires can add up pretty quickly if you have to replace all four at one time. The sedan was the cheapest car Franklin offered, but even its $2395 price was four times the cost of a new Model A Ford. But though Franklin had its sporty models, it never sold cars on that basis. Equally unusual were the cars’ all-around full-elliptic springs, which provided a smoother ride and much reduced tire wear than most competitors’ half-elliptic suspensions. Franklin was ahead of the industry by selling more sedans than open cars before 1920, and sedans remained the models of choice in the ’30s.
