I can't use ANY skills on the emitters, they do not have the skills icon in it, only backpack, look at and cancel, I cannot open the skill menu....

I am stuck in it for like an hour already.

Use a radio on them I think?
blowing them up maybe works too?

Agreed.
Try dynamites.
If there's an enemy near, a grenade or rocket should work, too.
Unfortunately you can't aim at the force fields in combat mode.

If you can't open skills menu then use numeric keys 1-8. Science is 7 and Repair is 8. Try them...

This. You have to use force use your skills on them, repair/science I think. I didn't use the numeric keys though. Unfortunately I didn't know about that. I pressed the SKILLDEX button instead to bring up a list of skills I could use.
Alternatively, the electronic lockpick can also be used from what I can remember

Thanks guys! Pressing 8 worked for me.
