What Bartolomeo said.
There is a difference between RAND CAM and the Rand Corporation. The corporation is a non-profit research firm. RAND CAM is trying to market a new kind of engine, with no evidence of success that I can find.
I did some research on this the last time it came up here, and just took a look to refresh my memory. I'm not sure who came up with the design for the engine, or for that matter how the thing is supposed to work -- the available information reads like the ads for 200 mile per gallon carburetors they sell in the back pages of Popular Mechanics.
Some how some JW's in Oregon and British Columbia acquired the rights to the engine and set up RAND CAM to sell it. They donated 50% of the stock to Watchtower, but retained the voting rights for themselves. They no doubt got a big tax deduction for the donation, while ensuring they kept control of the company.
I believe, from prior research, that one or more of the JW's involved in this were DF'd.
