I'm just greatful that Copper let us know about the FLUBE technology that EESTOR will be using to make layers and enable it to dominate future energy storage markets."

Should be good as gold.  When is it supposed to be announced?"

If you are interested FLUBE stands for "Field layered ultra boundary extrusions".
