I think the 16 number is fairly accurate for the existing space. Maybe + or -. As is the facilty is not going to double. I guess its possible to expand the existing building, but probably just more cost effective to lease.
Going back to devining the purpose of lqmt lf. Not sure I would want mfg expanded in US, why not outsource to existing companies with people, process, tech in place?
That would be the best ROI UNLESS big enough contracts are brought in to both create a new facility and fill orders. Could happen but not yet in reach. Certainly a 1 or more year plan to do that.
