I modified the tech file of the demo in order to allow production of Tokamaks, common ore mines, and GORFs. This makes the scenario beatable now.
I tested the scenario and managed to beat it on Hard, but didn't complete on the other difficulties. Although it appears there is no difference in difficulties anyways.
I'll build up a separate post about it later, but for now, if you add the attached modified Eden demo tech tree to your Outpost 2 root directory, it should update the scenario and make it winnable. You should probably delete the file dtek_e.txt from map01.vol to remove the original file, but it appears on my computer to be taking priority at loading a tech file outside of the vol file first, so if you don't delete the original file, I think it will work anyways.

EDIT: Removed the attachment. You can find the new tech file here now:
