Maybe, there is no such thing? An idea, is simply an idea.
One of the ideas I had
Project Loon by Google
Not exactly the same thing. But, I do think that there is a lot more potential, for a whole lot of other industries in this space. [Blimps/Aerostat/Balloons]. Also, that there are a lot of benefits. Specially in comparison to the traditional way that most infrastructure is laid out.
Ideation is like evolution, it builds upon itself.
