Is that a CPU cooling fan that you've modified? I'm really not sure for how long that will cope with the strain of high speed use... Still, only one way to find out!
Your design strikes me as awefully similar to the real full size plane, the Edgely Optica. I reakon you could make a pretty nice scale model of the full size with a little work.
EDIT: And seeing as performance will almost certainly be below what a prop could provide, scale appearence is really the only practical application of this. That, and the fun of seeing whether it will work or not!
