Wonder what they were used for...

Some stuff I have come across point toward some kind of free energy device. Other sources suggest some sort of mind control technology.

Also read where Napolean spent the night in the pyramids, supposed became possessed from the experience.

Would definitely be nice to get clarity on some of this stuff, hopefully we get more than the 40 percent disclosure that Q alluded to (i.e., 60% must remain classified...at least).
