By the way, although I believe they'll achieve cash-flow positive in their sleep (literally), it's not a requirement for proof of concept. Showing increased sales, increased profit margins, and decreased cash burn in Q4 will prove with numbers that it works.
I don't belive there are any hurdles nor obstacles in front of them whatsoever to get proof of concept -- they have feedstock suppliers. They have fuel buyers. They have machines that work.
That's just my opinion. I'll drink my champagne alone for now. ;)
