Area power poles, replacements for a huge number of small power poles used to span an area. Spans over 32x32 and 64x64. The cost are only slightly higher than if you build the grid one by one.
Could you make it so the flying power power poles don't stack on top of one another, kinda sucks to place an extra power pole in a spot where it has zero effect, this matters a lot for tile-able blueprints that use the power poles. it looks like the activity is kinda dead here though....
