It was a weighty decision, not taken lightly, but X Prize officials voted last week to bar a group attempting to harness gravity from entering the contest aimed at promoting space tourism.
The X Prize Foundation notified Gravity Control Technologies (GCT) of Budapest, Hungary that its application to become an X Prize team had not been accepted.
GCT was founded in 1999 and is a privately held aerospace research firm delving into superconductivity and Zero Point Energy Field physics in the hopes of achieving one-hundred percent propellant-less propulsion technology for flight.
