I just went through the slide deck that was used for the presentation. It's very similar to the one they've used previously.
Don't get too caught up with the fully funded and no debt talk. While true, the reason for that is because the company has a history of using stock to fund the company. Then when the number of shares starts getting out of control, they issue a reverse split. I don't know if that trend will continue, but the stock chart hasn't looked pretty once you factor in all those reverse splits.
The technology seems like it is very easy to understand, very effective, very targeted, and fulfills a dire need. But sales won't come until testing is complete. Hope they're working on that now.
