Full Description

The Queen's Chamber walls are coated with thick salt encrustations (up to 12mm). The south shaft contains traces consistent with zinc chloride (ZnCl2). The north shaft contains traces consistent with hydrochloric acid (HCl). These are the exact two chemicals needed to produce hydrogen gas: Zn + 2HCl → ZnCl2 + H2.

The Queen's Chamber also contains a large corbelled niche (4.67m high) of unknown purpose, consistent with a mixing/reaction chamber. The Grand Gallery above provides a 46.7-meter inclined channel for hydrogen (lighter than air) to rise toward the King's Chamber.

No conventional theory (tomb, cenotaph, observatory) explains why zinc chloride and hydrochloric acid would be present in a sealed stone chamber. The chemical residue is consistent with industrial hydrogen production — a process supposedly not invented until the 18th century CE.
