My opinion is that the valuation of this company seems low compared with the valuation of the IP technology licensing business plan ahead. Expanding into multiple industries and global regions has just started.
My guess would be that these are probably vessels that the Army Corps of Engineers already uses and they conceptually retrofitted the Ozonix mobile platform to fit these vessels. Just my opinion. Interesting they named it Ozonix Sentinel. Sentinel is a guardian term and has an Army Corps of Engineers ring to it (in my opinion). I hope there is a pilot program coming. Interesting set of rivers that are given as examples of needing cleanup along the east coast in their map on the website. Seems like these must be targets of importance to the Army Corps of Engineers.
The National Wildlife Federation has a link to support The Clean Water Rule. It generates a letter to your Congressman / woman to show your support. I assume that if you are invested and interested in Ecosphere and its patented solution for clean water that you support the updates clarifying the Clean Water Act.

That should get you to the article that has a link to show your support.
