Ann: December 2019 Quarterly Update, page-9

Ed, that proof should come inside the next 30 days, judging by the enthusiastic commentary on multiple customers. We have a very long process to convert interest into an inked in contract...but then it is a long relationship.
plus, remember, the doctrine of social proof will shorten this time lag as more companies come on board as in ‘so an so have gone with CG1, it must be good’.
when they have the runs in the board they might be able to incorporate the trial process of optimising the right mixtures (currently the reason for the lengthy runway between interest and contract) as part of the contract and a revenue generator itself...a set up charge if you will.
This business should be international and surely it should be watching India which will become the largest operator of coal fired power plants going forward.
personally, I don’t think we will get to see this played out. A few more big wins and we will attract a takeover offer. We are a juicy sprat swimming in a shark tank.
