Nope. Fusion cores. I have about 30 or so right now at level 40. I've only ever taken about 5 of those from the fusion generator looking things. I'll take a screenshot if I get the time of a box with fusion cores in it.
I seemed to find fusion cores just fine with the ammo scavenger perk. It seems that the game sorts fusion cores under "ammunition", and can therefore occasionally be looted in fair quantities (3-7 has been my luck) and I am currently sitting on about 30 cores at level 34. Unless that is the same for you all too, maybe I just don't use power armor enough.
I'm not trying to suggest the image you made was faked, but it's pretty easy to do: http://imgur.com/WqeYyWL
Edit: Seems I spoke too soon
Nevermind, it's back and bigger than ever
