Interesting use of technology.....I wonder if they will actually put it into production? The only problem I can see is Air Traffic Control and navigation issues, but it certainly looks like a fun machine. Clever use of what looks like one of those "Hopper" balls as the base.
if they develop it to the point where it has a reasonable range, it would certainly be of interest to many people.
If you saw one now, you might be forgiven for thinking you where looking at a UFO though!
