Homebuilt Question

I'm wonder how this would play
out:

a. Person designs a unique plane,
one of a kind, no other ones to
compare it to.

b. It is a single-seater.

c. It has unique control surfaces,
and only someone "trained" can
fly it.

d. Gear is retractable.

e. Propulsion is "rather mysterious".

Now, how would this plane be certified?
No one else can fly it. Much of the
technology is sealed beneath carbon
fiber. No one knows how fast it goes.
It is homebuilt. Builder is willing to
concede that it isn't lightsport.

Thanks.
