Larry Page's ambitions are huge and grow bigger every day.

Already, he has Google working on self-driving cars, artificial intelligence, robots, aging, and drones. At Google, they call these efforts moonshots.

The latest problem Page wants to solve: inefficient airports.

In an excellent report, The Information's Amir Efrati writes:

With friends and colleagues, Mr. Page has talked about his desire to build an airport that would be more efficient than existing ones. For example, his argument against the hyperloop train—a concept for transporting people from San Francisco to Los Angeles in 30 minutes—is that planes are just as efficient; it’s the airports that are the problem. (Other transportation experts have expressed similar views.) It’s not clear how Mr. Page would go about building such an airport.

Apparently, Page wants to build a model airport to show the world how it could be done better. Efrati says Page also wants to build a model city.

It's all part of an initiative called Google 2.0. Efrati reports that Page cleared out space on his floor of Google's headquarters a year ago and asked 100 employees to help him figure out what huge problems in the world Google could solve.
