Seriously though. It seems reasonable to copy nature (wings) and hope it works. Lots of engineering has been inspired by nature's shapes. Not too many things in the sky that look like a kite (alive).
But, how are you going to rest it on shore? Wind is gonna blow it away (won't it?).

I know Naish is really rolling the dice on this one, that's all I know.
If Ozone actually releases one, I would be very tempted (even though it'll just blow down the beach into a tree the first day!)
