To attend a conference all they have to do is dump and additional few million dilutive shares into the market to pay for air fare and lodging. They could do that over a couple of weeks and find a few gullible buyers each day. Of course if these know nothing do nothing management idiots attended a conference with videos of their wonderful green tea cup with hat in hand they might be able to collect enough cash to actually defray the cost at least one of the meals on their trip so that us shareholders wouldn't have to shoulder the whole trip cost. Reality is that they said they have a wonderful prototype and would like to take pictures of it but just can't because it would be too hard for them to do. It's time they either show what they have or admit they have been running a scam and have nothing beyond the green tea cup.
