March 1999
I came across Richard Noone's 5/5/2000. Although a doomsday book, most of the content is excellent and oriented towards ancient cultures. Noone presents Edward Kunkel's research which had been presented in the book, The Pharaoh's Pump. Kunkel had presented an absolutely fascinating graphic description of the subterranean chamber being part of a water pump. There is something intuitively correct about his drawings of the subterranean sections.

Kunkel's Drawing of the Topography Associated with the Great Pyramid

June 1999: Model #1
Construction - cement blocks, 3/4" plexiglass ceiling bolted to top of model, epoxy interior and constructs. Waste gate on dead end shaft, closed bottom of pit, proposed output through well shaft. Result - Doesn't run, ceiling flexes and leaks despite extensive reinforcements. Eventual catastrophic failure of cement blocks. Positive aspect: Use model to make rubber mold for next model.

September 1999: Model #2
Construction - Epoxy resin, fiberglass, addition of 4" ABS ceiling cap, glass wall, output through pit and dead end shaft. Result - Doesn't run, bottom of model cracks. Positive aspect: First time viewing of water vortex in sub chamber model.
