I've been rooting around the web trying to dig up some information, here's what I found.
Rand Cam was formed by some JW's in British Columbia (led by a man named Robertson and/or his family), to develop and market the "Rad Max" Engine. Link with spiffy graphics here Link This engine is not as revolutionary as they make it sound, lots of people have tried (and failed) with similar designs. another link There's a reason you've never heard of these: they don't work very well.
Rand Cam is now owned by something called REGI Technology, based in Spokane, WA. There website has lots of breathless talk about the technology, but no reported sales. They don't have any contracts with the military, or anybody else that I can find.
The WTBS claims the SEC filing showing them owning five million shares is a mistake. Here is my speculation about what might have happened:
I can’t tell from public information if the SEC
paperwork listing the WTBS has an owner was 1) a mistake, 2) a purchase, or 3)
a gift from the Robertson’s. It is possible
they donated the shares to either curry favor with somebody or gain a
significant tax write-off (or both).
In any event, the WTBS probably never made any
money off this (the stock is selling for six cents a share, i.e. its worthless)
and does not now own the stock. In other words for the XJW community I don’t
think there is any story here, beyond the possibility that the Robertson's were either conned into buying a worthless patent, or they were scamming somebody with worthless stock.
