Here is an interesting article about an inventor from England who has created a hoverdrone. It is basically a cross between a hovercraft and a helicopter which looks like a flying saucer. It's shaped like a bell with the rotating blade above the bellshape. The air is forced down around the sides of the bell which I assume causes lift. This thing looks like the hover drones from the Dark Angel TV series. The real question is can they scale this thing up so it can carry a human?
