There are quite a few of these in the various tech trees. Question: does Stardock know about them all, or should we start a thread that lists the empty descriptions that we have found, to make it easier for them to fix?

Enhanced Defenses for the altarians, dont do anything and its not a part of any tech line, its just a random tech at the bottom of the tech tree that does nothing. There are several techs that dont have a description too, but i dont think listing them will do any good, this is something they will certainly double-check at some point.

Okay, we're only one step away from the Release and I've noticed that Hardened Armor still does not show it providing any bonus or ship component. Hope this one is completed-it's a good concept. I've not seen the evasive action tech yet so I don't know whether it has been completed.

While I'm here, I'll also note that the first two levels of farming tech have an improvement that looks identical. Back in DA, there were two different icons for those improvements. On the tech tree, you can see the old icon sitting along side the "new" one that looks like the first level tech.
