I have a small but cool idea for all required maintenance machines, especially turbines :
-The robotic maintenance arm : Capable of repairing and taking care of a machine if placed next to the maintenance hatch ( made mainly for turbines ) :
MKI : It will at the cost of only EU ( but for a lot of it ) : repair stuff, remove "this thingie that shouldn't be there in the first place" xD, and, will at the cost of a sh1ton of eu, and replace the dead turbine by a fresh new one ( so at least we will have an automated legit way to do that ).
MKII : Everything like before, but it will also try to regulate the turbine turning speed and angle, so you get less damage over time. It will do that passively.
MKIII : Everything like before, and will also repair any turbine present at the cost of eu and liquid uu matter.
