A rare look inside Tesla's Gigafactory 2 in Buffalo

Using part employee, part equipment, solar roof tiles are being built inside the new Gigafactory 2 on South Park Avenue in South Buffalo.

It's a complex process, and one 7 Eyewitness News Reporter Ali Touhey saw firsthand during a tour of the plant. Our cameras weren't allowed to record anything on the manufacturing floor. Tesla provided these photos.
