At present, / in order to go into space, / we have to

use <span class='nw'>rockets</span>. /

They require <span class='nw'>huge</span> amounts of <span class='nw'>fossil</span>

fuel. /

On the other hand, / the space elevator / is much

more <span class='nw'>[energy-saving]</span> and [eco-friendly]. /

Although the

space elevator / may use a lot of electricity / when it

goes up, / it can also produce electricity / when it comes

down. /

That electricity can be stored / in a <span class='nw'>battery</span> /

and used / when the elevator goes up again. /

The <span class='nw'>cost</span>

of a single trip / on the space elevator / may be about a

hundred times lower / than that of a trip on a rocket. /

In addition, / <span class='nw'>unlike</span> rockets, / the space elevator itself /

will not produce any carbon <span class='nw'>dioxide</span>. /

With the space elevator, / space travel may no

longer be a dream. /

Someday in the future, / even

<span class='nw'>elderly</span> people and children / may be able to go into

space / without any special training. /

Also, / the space

elevator has even more potential. /

It might become

a <span class='nw'>gateway</span> / to other planets. /

Imagine going into space /

with the space elevator, / changing to a space ship, / and

starting on a journey / to <span class='nw'>Mars</span> or <span class='nw'>Jupiter</span>. /

Such an

exciting experience / may not be so far / in the future. /
