A friend of mine sent me this one from a student in her history class... We've heard Pyramid Power theories before but here's a certain one she heard. The following claim is a quote from her emails... She even included a picture her classmate sent to her... (I guess people make diagrams for something they didn't test?) Here is a debunk from Michael Hiser of the (Interior lighting) aspect... As for the rest of the theory. Does anyone else have any debunks for the "Power Plant" aspect? Its a fascinating theory, but nothing more it seems... I think its great that people are fascinated by one of the coolest world heritage sites, but of course a lot of misconceptions can be made!
