Hybrid Cars are only a small step in the right direction.

"All About Cars" writes: "There are two varieties of hybrid automobiles. The mild hybrid features a gas-powered engine that supplies the main propulsion to move the car down the highway. An electrical motor provides an added assist in situations where an extra power thrust is needed. The electrical motor also serves to recharge the car battery while the car is on the highway. The full hybrid features a gas-powered engine, with an electric motor and battery as well, but in the full hybrid the electric motor can power the car on its own under certain circumstances. These features will give your new hybrid automobile the best in gas saving features."
With the gasoline prices going higher and higher, I wonder how long it will take to develop a more affordable technology to power cars engines.
