15. Reporter : Professor, in the
nineteen seventies, scientists
predicted that
the world's oil reserves would have
all been use up by the beginning of
the twenty-first century.
Prof. K : Those prediction were
highly exaggerated.
However, in a hundred years' time
at the present rate of consumption,
we will have use all the available oil
resource.
Therefore, we need to find clean
renewable fuel, especially for
automobiles.

16. Reporter : What other fuels are
being developed?
Prof. K : We are working on alternative
sources of energy such as biodiesel, solar
energy, electricity, and hydrogen.
Reporter : What will we be filling our car
tanks with in twenty years' time?
Prof K : According to the U.S. National
Engineering Academy, by 2024, half of all
vehicles will be running on part
electricity and part of gasoline.
They also predict that by 2038, all the
new cars produced in the U.S. will use
hydrogen.

17. Reporter : That's a big change in
relatively short period of time?
Prof. K : Yes, science nowadays
advances very quickly,
and changes in technology that
affect people's every day lives can
occur very fast.
I wouldn't be surprised if most of us
will be driving hydrogen-powered
cars in the near future.
