AIRROUTE & AIRTUBE...	TRANSPORTATION NETWORKS
		AIRTUBE and AIRROUTE networks, in different proportions, are dependent from their "individual" (not - collective) aspect. Indeed, switchings and points of entry-exit of the network impose a minimum distance between two spheres or between two modules. And as result a maximal transportation capacity for a "tube". Between two points with great traffic (i.e. Brussels/Paris) , instead of to split immediately the " tubes", it will be necessary to calculate an average term, and to develop systems "more or less parallel" between these two points with great demand. The low consumption of energy and the speed of systems will allow indeed to develop "secondary" networks similarly to main connections. Increasing thus the main connection capacity and at the same time the secondary network profitability.
