Is there a geometrical energy system that surrounds our planet? ... a super grid involving polyhedral forms, ley lines, earth energy currents and archaeoastronomical alignments?

From ET flight-paths to anti-gravity, the grid has many astonishing claims attached to it. This book unravels the many theories to give an overview of this incredible subject.
