There exists NO evidence that can confirm or support this statement.
In 1968, Erich von Daniken stated that the Ark of the Covenant was a radio transmitter that the Hebrews were instructed to build by "ancient astronauts" during the Exodus, by giving Moses exact instructions down to the very inch on how and where staves and rings were to be fitted, and from what alloys the metals were to be made, with the warning that no one should come close to the Ark because it was often covered with flashing sparks.
Years later, when David had the Ark moved which almost fell from the wagon it was on, Uzzah grabbed hold to stable the ARK and was struck dead by an electrical charge.
Now if the Templars discovered the ARK in Jerusalem during their stay during the CRUSADES, they would have had to have knowledge to recharge whatever electrical conductor powered the ARK, and how to keep from being electrocuted like Uzzah.
