where did linc's gtl tech come from, page-4

Thanks, did not realize Linc was doing it all internally. I am looking around for other ways to play the UCG boom, in addition to Linc (and CNX, CXY, etc).

But it looks like nobody has a lock on the GTL IP. And there is tons of stranded coal out there, so the coal owning companies don't seem like the way to go. Although some of these companies with tiny market caps and huge coals resources are tempting - Libery Resources and Altona for example.

Not sure what the situation with UCG IP is. Didn't Linc get there technology from Ergo Exergy?
