The patent text has at least one typo error, in my guesstimate; I will point one one right now: 

Traction for groundgen seems to be being neglected in some AWE text.
Notice that in AWES forum we have not neglected this huge opportunity;
that is we have been rehearsing the pulling of ropes to drive generators,
the pulling of carts with axle generators, the pulling of water hulls
that hold hydroturbines.

This note realizes that traction is involved in the commonly
researched pumping cycle; but this note has focus on long-stroke
non-pumping traction opportunities.

This note is primarily a refresher reminder note. It hurt hearing
TedX talks on AWE that seemed to fully miss the long-stroke traction
realm. It is not just travel of hulls for freight that traction
serves through kite systems. kPower, Inc. has long supported
long-stroke traction opportunities; one sector is the use of many
long-stroke kite systems gathering traction forces to drive ropes to
remote legacy generators.

So, when writers or AWE speakers present AWE options, consider flygen,
pumping groundgen, and traction long-stroke groundgen. Those ... and
all the wonderful ways kite systems may put put to work to do direct
tasks that are not electricity generating.
