I suggest that the general Tech/Mech section be split into Mechanical things and Electrical things (not covered elsewhere).
Unless I've missed it, there does not seem to be a section for batteries or electrical components and it seems wrong to bury such an important subject amongst other unrelated stuff. Or you could widen Solar Power to Electrical Power.
