Car companies are looking at a variety of ways to get more miles out of a gallon, a bushel or a volt.

As a reminder of just how far some alternative technologies can go before they simply fizzle out, here's the Chrysler Turbine Car.

Turbine-powered cars are, literally, jet cars. A small jet engine spins turbines that drive the car's wheels. The main advantage is that jet engines can run on just about any flammable liquid including gasoline, diesel fuel or kerosene.

In 1963, Chrysler made 50 of these cars and gave them to "ordinary American families" to use as their daily drivers.

The planned next step was to produce 500 turbine-powered Dodge Chargers for sale to the public, said Todd Lassa, who wrote about the turbine cars for Motor Trend Classic magazine.

But that never happened. For all their jet-age promise, turbine cars offered no better fuel economy than regular cars and produced more pollution.
