This week's Question: Google co-founder Larry Page reportedly has invested millions of dollars in two startups that are developing flying cars. Bloomberg reports that Page has spent more than $100 million on Silicon Valley's Zee.Aero, and is also funding a similar firm called Kitty Hawk. Zee.Aero's plans have included building a prototype flying car capable of taking off and landing vertically. Werner Goertz, a research director at market research firm Gartner, said that the flying car is unlikely to catch on with the general population but may become a reality for "the 1 percent of the wealthiest people." Aside from socio-economic barriers, he said companies would have to design a cost-effective battery that would carry a charge strong enough to lift a flying car for an extended period of time.
