The blue lines are power cables. Not sure why they show on my map and not yours. Got a working nuclear plant now and my energy demand has skyrocketed by replacing all my Assembling Machines with Assembling Machine 3's. Solars manage through the day but can't recharge the accumulators sufficiently now. Scrapped my boilers and put my nuclear reactor onto a a smarter SR switch that I googled.

Plate consumption has sky rocketted with the improved machines so later ones stopped working so grabbed a third iron ore field now.

Still not automated purple science or got yellow science yet. Doing manual purple science.
