The thing that's really neat is that this comes the closest - in a PRACTICAL sense - to the notion of a "flying car" that I've ever seen. I don't mean that it would work like the Jetsons or Back to the Future. I mean that as a practical means of moving about using both air, water and ground effect modes. No - you're not going to use this on the road or above the streets of a city. What you -could- use it for is for interface travel. Particularly in cities with waterways. (And that's most large cities. We humans tend to build close to the water.) Take Hong Kong for an example. Their new airport is on an artificial island several miles to the west of the city proper. With this wing/hovercraft, you could use the hovercraft as an airport to city shuttle. Take a load of passengers from the terminal and use the harbor to get to the city proper. If you have a hotel close to the water, you might be able to use the ground effect to pull right up a ramp to a back entrance to the hotel garage. Just a short walk from there to the concierge.
Some of these advantages were already proven by hovercraft and hydrofoil shuttles. But this just takes it up a notch, I think.
