I dunno. The whole "no tech powers at all" thing seems a bit strange to me. Would a technopath with certain tech they keep on hand be fine?

I was thinking that their technopathy wouldn't literally be technopathy, but a form of aura extension, so to speak. Their race would have an energy signature that they can extend into tech to power it up and control it, and can override other power sources to bring the tech under their control. Their own tech is built without power sources due to the fact that they can extend this energy part of themselves into the tech to power it, which would mean power sources would be a bit redundant for anything that's not too big. This would create the effect of the race being made up of technopaths, when it's not really a psychic ability.

I'll have to create limitations and do other things to balance it out, but I think I've got something pretty neat going on that can definitely be worked with.
