Yes, maybe it "works" somehow, there's also pictures of people surfing with garbage bags.
Seriously wtf is wrong with you?
But if you really need kite for higher winds you should have a smaller kite for that.
You kind of keep missing the bit about use when you don't have said other more appropriate kite size....

If they are uncertain then how can you be certain they are unsafe?
Those pictures from airplane wings shows how primitive methods has to be used because there is no technology (yet) to do it better.
Primitive lol, you must have a strange understanding of the word primitive to describe some Airplane technology as that. Let me help you with your English, if as you incorrectly describe there is no "better" technology, then by that definition something can not possibly be primitive. Now there is superior technology, but most likely not in other facets , economics, manufacture, durability, and lack of known qualities.

Great for those in kiting too. Board start take-offs, kite reverse take-offs,jump take-offs, jump landings.
There has been prototypes of wings that alter they shape without kinks
It's unhealthy your obsession with kinks and bridles and tubes. Is it that you are still in the closet?

Amazing plain old flaps as used on Planes and kites have agility benefits.

Really, then why are they used ?
