Another potential problem, that someone else on this board has brought up before, is that we can't seem to determine what patents AFPW actually holds. There's PRs out there that reference the company's patents and patent filings, but as far as I know I can't verify that they actually hold a legitimate patent for their technology - whether it be the powder formula, or the PBIS-1000 reactor, or anything else for that matter.
I've sent two emails to Mike Graff of IRG, which is Alumifuel's public relations consultant, and have not received a response either time.
