but. there can be small floating platforms,

 

that can assist lift of the lines

 

and keep it there, as extensiion.

 

 

if that extension lines in a different

angle gets in the way of the

vehicle depending on the line,

 

the line will need to be designed so

that the vehicle uses the,

 

'line within a line',

that is travelling along path the belly of the main line,

and drawing power from it as it travels.

 

 

 

 

Whether such setup is worth it or not is a question.

 

Alternative to air or water travel.

 

 

Taking time to get from one continent to another.

 

 

maybe for supply transfer. in more timely manner.
