how are you going to get a 1GW generator upon the top of a 10 km tower ?
how much does a 1GW generator weigh ?
wind loading is the amount of side pressure by the wind on your tower,
how much should it be in the jet stream ?
How wide is the base of your tower in km? (you have weight of generator,
and wind loading)
