TECHNOLOGICAL CHANGE:

There have been dramatic technological changes over the past 100 years changes have been taken place in the three main areas. For example, electricity, motorized transport and space exploration. Further dramatic change seems likely to in the following three areas: car technology; camera technology; alternative energy sources.

Significant changes car technology has developed rapidly in the past few decades. For the past 28 years the battery cauterized devices, that replaced keys, rely on weak radio signals emitted by tiny transmitters the active a car's door lock motors. The transmitters had a range of 15 feet, although, trees or wall could block the signal. This is still likely to be a major area of change in the coming decades: e.g. car engines uses both internal combustion engine and electric motor for running the car intelligently. The electronic system decides when to run the car on electric motor alone, when to run it on both electric motor and engine, when to run it on gasoline alone and when to use motor as a generator and convert kinetic energy from the wheels into electricity to charge the battery camera.

Camera technology astounding changes consumers more easily and better by all digital cameras have a built in computer, and all of them record images electronically. Also consumers can just charge the camera and use it for the rest of the day. Furthermore, they have a ship that can have a thousand of memory also it has video tape.

A major challenge facing the world at the end of the 20th century= global warming resulting from man-made pollution. It is likely that alternative energy sources will soon be exploited more seriously solar, wind and wave energy. Nuclear energy Perhaps we will abandon high-speed vehicles and accept slower, more energy- efficient ones.Even though, there are already inventing flying car in the air without using gasoline by using the wind.

To conclude, we can expect major changes in the areas of car technology, camera technology and energy use.
