Was it Daniel who recently suggested putting legs along a
tether to keep Doug's spinning turbines off the ground? [Ed: No.
Rather, it was Darin Selby*]
Its true that airplanes have landing gear & flying insects find legs quite
handy. KiteLab experiments from 2008 found bamboo landing legs on small
kites & payloads were effective, but the idea was not deeply explored. It
seems likely that an entire train of kites that would otherwise not tend
to relaunch can land on legs (or even wheels to weather downwind) ready to
easily relaunch. Legs help wind to engage wing for early relaunch & also
keep wing clear of adverse surface conditions. Even if some kites land
wrong, the rest can initiate mass relaunch.
Kite & tether legs add some weight & a potential to foul a slack tether,
but might prove an essential method nevertheless.

- The potential of a small LTA kytoon for starting a launch of
large--or even huge--kite arrays. Think of the power of a small spark
igniting a huge plains grass fire. Reverse domino cascade effect.

- One could also put a light hoop structure around the tips. This
would prevent damage but would not allow rotation until lifted.
No, it was not I who put it forth to the
group, but I was thinking along those line you've stated below after I
heard about the landing. Was thinking of something simple light weight,
strait shaft for length of SpiralAirfoil two bearings, one in front and
the other bearing in the back with triangulations attached, possible
pontoons on both ends and then pontoons on self launching kite, pontoons
could be designed with lift in mind.

- How do you stop your LTA device from blowing away in a storm like

above the bad weather to avoid losses and obtain perpetual flight.

My guess: depower working turbines to reduce system drag; such will
give higher angle to the holding tether set; perhaps increase buoyancy
of lifter LTA with onboard gas controls. Get above weather; avoid
fighting bad weather at ground (or bad guys in Desert Storm wars.)
