In the next twenty years, the world will have solved the major problems of
             transportation today. Global warming news will no longer be splashed over
             news screens nation wide. Traffic jams will be a thing of the past as some cars
             take to the air. In fact, traffic jams will be documented at the Smithsonian to
             ensure future generations have a sense of what traffic jams were. The next
             twenty years will see huge advancements in the area of transportation making
             In numerous cities across the country, the personal automobile is the
             single greatest polluter. Emissions from millions of vehicles on the road add up
             and cause the global warming problem talked of earlier. The solution is to have
             much more efficient vehicles that produce fewer emissions with every mile. This
             is why in twenty years the electric vehicle, or EV as most scientists refer to it,
             will see its nation wide introduction to roads everywhere. Electric vehicles are
             actually present in the world today. Unfortunately, the price of these EVs well
             exceeds the price of a normal car. In twenty years however, the price of these
             vehicles will have dropped dramatically with the new invention of the flying car
             swaying people's interest. Any normal middle class family would be able to
             afford at least two of these electrically powered vehicles. While the families will
             be benefiting from not having to buy gas every week, the environment will
             benefit by not taking in as much emissions as in the past.
             Electric vehicles or EVs, are vehicles that are powered by an electric
             motor instead of an internal combustion engine. EVs use electricity as the "fuel"
             instead of gasoline or some other combustible fuel. The power for the vehicle is
             stored in many large batteries in the bottom of the car, from there the power
             goes to a power regulator where it is changed from DC power to AC power. The
