That is indeed the E.ON warehouse in Bondeno/Ferrara.
Which photo, or both, and how would we know?
Exhibit 3 is described in the IH Second Amended Answer this way:
QuoteThe Six Cylinder Unit in the Proposed Second Amendment is separate and distinct from the E-Cat Unit or Plant as referenced in the License Agreement, the First Amendment, and the Complaint. Photographs accurately depicting the Six Cylinder Unit are attached hereto as Exhibit 3. The Six Cylinder Unit remains in North Carolina.
It could be implied is but not stated that the photos were taken in North Carolina. If there is clarity here that the other photos were taken in Ferrara, that is prima facie evidence that the Exhibit photos were also taken there, though possibly at different times. Rereading the Answer text, the point of the Exhibit is to show what a "6-cylinder unit" looks like, not that the photo was taken in North Carolina, which they do not actually say. The North Carolina statement is separable from the photo.
