Well of course. If it is a scam, everyone should know about it. But there is something called a "trade secret" and they may not want to give away too much information just yet. Besides, what I quoted was from an informational article about it, like you'd read in a newspaper. As such, too much technical information would be out of place.

My uneducated guess on their process is some sort of pressure / cracking type process like they do with petroleum.
