"Experimentation and discovery of new technologies is what really drives the auto industry and a walk through this exhibit is an entertaining trip from the past into our future beyond petroleum," said Dick Messer, director of the museum, in a statement.
Electric cars, clean and quiet but slow, were popular with the more practical-minded. They were seen as women's cars, appropriate for running errands around town.
Even after gasoline engines had improved enough to gain wide acceptance, engineers kept up experiments with other types of power. The 1938 Citroen 11 in the Petersen exhibit was fitted with a coal gas generator so that it could be driven despite World War II gasoline shortages in Europe. The fender-mounted generator produced a combustible gas by partially burning wood or coal.
Turbine cars used small jet engines to spin turbines that, in turn, powered the cars' wheels. One of the great promises of turbine power was that jet engines could run on a variety of different fuels including gasoline, diesel and kerosene.
"Chrysler, in the years right after World War II, was very serious about trying to make the gas turbine practical and economically viable," said Bob Casey, transportation curator for the Henry Ford Museum and Greenfield Village.
At the time, Chrysler's plan was to produce 500 turbine-powered 1966 Dodge Chargers that would be sold to the public, said Todd Lassa who wrote about the turbine cars for the current issue of Motor Trend Classic magazine. Those cars never appeared.
Ultimately, decades of turbine car experimentation led nowhere. They got no better fuel mileage than traditional gasoline engines and they had trouble meeting new emissions requirements, Lassa said.
Car companies have, most recently, turned to hydrogen as a promising "fuel of the future." In a move reminiscent of Chrysler giving turbine cars to American families, Honda has put its hydrogen fuel cell-powered FCX, one of which is in the exhibit, in the hands of real customers. Other companies have fuel cell-powered trucks in fleet use.
The fate of hydrogen fuel cells remains to be seen as more attention is given to the problem of extracting the hydrogen from sources such as hydrocarbon fuels.
"Engineering is not an easy business because for every advantage you have to look at disadvantages with the technology," said Lassa.
