I also don't understand what the patent is about. ROHR was doing similar things 25 years ago

ROHR was just a ducted fan/propeller from what I can tell, a very cool one though.
Using the search term "Hoversurf" in Google Patents I could not find anything.
I'd like to see their patent, please post it if you find it - that goes out to anyone reading this. I have to get back to work.
