Something doesn't "smell" right about this story. First, $300,ooo in a grant and yet what is there to show for it? I too, would be very interested in where all the money went. 
I hopped over to his website and did a google earth search on the address listed there. His company headquarters is one of those rent a mailbox places. 
Then I paid a quick visit to Alaska Court View and Davidge has quite a few small claims judgements against him. A couple of them related to a company called Aqueous International.

Something just isn't on the up and up about all of this. Call it instinct.
