I don't know how much money they made but I assume that most if not all of the capital raised at their IPO went into R&D. I suppose its also possible that he spent a lot out of his own pocket as well. I'm sure its been quite expensive to develop the booth especially considering it's never been done before.
I can't see getting this far and failing, I suppose he could fund the thing himself if he had too but from reading the 10-Q and such it certainly doesn't sound that way. He has deep pockets, its not like he is some starving inventor who has spent every last dime on his creation..lol.
If for some reason this thing fails because of funding we'll know it was just all BS.
