Google cofounder Larry Page reportedly is working with two Silicon Valley startups to develop a flying car. One is Zee.Aero, which Page personally has funded since its launch in 2010, when it set up shop next to Google's headquarters in Mountain View, California. The firm reportedly has filed a patent application for a small, all-electric vehicle that could take off and land vertically. Page is said to have invested more than $100 million in Zee.Aero, which has about 150 employees and an airport hangar where prototypes are being tested.
