Who knows why anyone does anything?
Ranger doesn't really promote the stock, it's probably off the mark to imagine that he's trying to pump it up to ease his losses. It's more likely that he's profoundly misinformed about the HYVR system, and science in general, and that he lashes out in anger because he's convinced that secret and dark forces have conspired to keep the HYVR technology off the market, and he supposes that we're in league with the conspiracy. If you don't like getting yelled at Mattg, then trying to teach pChem to devotees of an impossible energy scheme is the wrong hobby for you. This is the responsibility of people who like to get yelled at.
Oh, and don't publish too much info about yourself. Not Ranger, but other perpetual motion devotees will stalk you.
