I went and bought the BPs for the large and medium container modules before realising that the AP Wharf and Shipyard (where I bought the BPs!) have both those modules waiting to have an EMP attached

I've checked out every Superfluid, Graphene and Antimatter Cell factory (including high-tech and ship-tech stations) I've come across so far but wondering if there's an installation common among games that's a good candidate for this?
