Ancient Egyptian Energy Source?

In this video, the commentator posits that the massive granite boxes that can be found at various locations may have been a piezoelectric lighting source. Filling these boxes in a reaction mass who exert pressure on the internal surfaces generating a piezoelectric effect illuminating the chambers that they are found in.

This video gives a brief explanation of the effect and showed that it was used elsewhere in the past. The Ute people had translucent rattles filled with quartz and upon shaking would be like a torch.

This final video goes into greater detail on what action happens and a clearer explanation of the effect.

The initial video raised in my mind a question about the conditions back thousands of years ago. In other posts, I have discussed the possibility of a periodic mass ejection from the sun. It would appear like a micronova expelling molecules of matter in a wave, not as a single projectile. The explanation for this is that we are currently under the influence of a wave of gas and dust known as the Radcliffe Wave. What happens to the dust and gas material as it intersects with the sun? Is it immediately blown back or does it accumulate until it reaches some critical mass triggering a major expulsion? Imagine the sun shaking out the dust like someone shaking a rug. Is it possible that some of the larger chunks impacted the Earth causing the extinction of the dinosaurs and the Younger Dryas? Could the remnants of these expulsions continue to circulate around the solar system periodically intersecting with the path of Earth ... giving devastating meteor showers. While in Turkey there are underground cities and Goblecki Tepi was actually buried to protect it for some reason, one would assume people may have retreated to caves or possibly built structures like the pyramids so that some people could be kept safe during meteor bombardments. This comment doesn't rise to the level of a hypothesis. It is merely a musing on some hypothetical possible events.
