I've seen this company's antics for five years. Believe me, he's good at fiction. Thermo Tech had a working system but they milked the public. Same could be said of Hydroflo and countless others. Bob may mine....may sell some goods....but in the end, the same principle (or in his case, lack of principles) applies.
I mentioned a while back that years ago he showed a picture of himself holding one of the drills. An individual called him out on it....an individual that WAS involved in the business. Bob learned from it. He's a smart guy, but he's also been dishonest. I personally don't believe he's changed. Every answer he gives, seems to give warrant to more questions.
At the very least, this one continues to trade like a pump and dump. After the release on 4/5, the stock got hammered on major volume. I'd be very surprised if the Cotton family hasn't made millions in the last few months through the selling, trading (or however they do it) of shares, rather than making money through his so-called business.
