It almost has a bit of Buck Rogers look to it. lol
The intake cover is a very interesting idea it will give you a clean airflow over the skin but I am not sure about the blunt end thing, but it has got to be better than a fan sitting dead in the airstream.
You might want to extend your slots into the cover and decease the slot in the fin itself for a bit more rigidity.
It does look pretty cool!
I really like the shape of the wing it may be a lot more pitch stable than your typical plank.
