The two-seater Transition can use its front-wheel drive on roads at ordinary highway speeds, with wings folded, at a respectable 30 miles per gallon. Once it has arrived at a suitable take-off spot - an airport, or adequately sized piece of flat private land - it can fold down the wings, engage its rear-facing propellor, and take off. The folding wings are electrically powered.Robot housemaids and three-course meals in pill form are still nowhere to be seen.
In other news, airships could soon be used for transporting freight, being faster than oceanic ships and cheaper than powered aircraft. While they're only talking about freight so far, I imagine that if you outfitted them with comfortable cabins, observation decks and satellite internet access, they'd be good for recreational travel as well.
