Remember, though, this is a *temporary* structure I put up to see if there's anything interesting in the surrounding area. If there isn't, it just gets deconstructed again--I don't build the thing and then leave it there, because once you've run a scan for a few minutes you'll see everything that there is to see in the list available in the scanner room, and most of the time there's just not anything interesting enough to bother leaving the thing there. Also, I don't leave the scanner running when I'm not actively looking for something, because that's just a waste of power whatever your power source is; plus, if you have the scanner HUD upgrade you'll get a load of annoying targets pinging on your screen.
