@Max....the guy in your video could only hover and be "pushed around" by his friends (the term "Friends" is used somewhat loosely in this context). But maybe it's like learning to ride a bicycle, or surfing, and just takes practice.
But please take lots of videos for our edification (and amusement :-)
@Tom-ii: They generally used an aft-pointng fan with rudders (much like an air boat). There was a "scoop" at the lower portion of the fan which channelled air under the body to fill the skirts. Thus, a single motor/fan ran the whole kit.
Hmmm -- this sort of gives me an idea. Suppose you had a reallyt powerful leaf-blower, so lots of "umph".
Now suppose you had two small flaps mounted on the back of the board -- spring-loaded to keep them closed -- each with a string that you could use to pull them open -- and if you did pull them open they acted like small jets pushing you forward...
I'm (only) guessing, but I think you could steer the board to some extent and cause it to move by managing where you put your center of gravity.
That is, if you lean forward (for instance), the skirt to the rear will lift a bit, allowing air to escape in that direction - thus pushing you forward...
Or, as others have intoned, add another leaf blower.
At my college, there was a regular hovercar racing thing they did with hovercars built there on campus. They generally used an aft-pointng fan with rudders (much like an air boat). There was a "scoop" at the lower portion of the fan which channelled air under the body to fill the skirts. Thus, a single motor/fan ran the whole kit.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
