Mirrors

The example above is literally a power generator in essence, just like in this star trek novel written 5 years ago which references the Gobi Desert.

I extracted details from the link that seemed potentially relevant since they match many other themes often appearing in Gobi Desert Disclosure:

"Thadiun Okona is selling a Husnock super-weapon to the Orion Syndicate when they are attacked by Nausicaan raiders, who steal the weapon"

The Nausicaans steal a power generator from the independent scientific research station, Stonekettle Station, on Skarda. This means the station's shield has failed and it will be melted by the sunlight when the day cycle begins. Geordi La Forge leads a team who establish a temporary shield to protect a small part of the station while the generator is recovered.

The Enterprise follows the Nausicaans back to their homeworld: It was devastated during the Borg Invasion of 2381, with the Federation failing to answer their distress calls or offer help afterwards. They are attempting to use the generator to repair the ecological damage. After a brief battle, the Nausicaans retreat to Skarda and tie the Husnock weapon into its systems, creating a planet-destroying weapon that they aim at Earth.

Van Helsing:

This movie actually shows at the start that Van Helsing works for The Jesuits:

His right hand man throughout the film was ordered by the Jesuits to assist Hesling's Quest quest, he created the followi:

"This weapon was invented by Carl. According to him, it can generate the same amount of light energy as the sun. Similar to a weapon in Blade II, it is an unstable combination of bottled magma from Mount Vesuvius and pure alkaline from the Gobi Desert. It generates a powerful heat intensity, and can instantly vaporize many vampires within a big area of the bomb as shown when the bomb cleanses an entire mansion full of vampires."

Notable links:

The Sun Country is a small lush rich country hidden in the mountains of the Gobi Desert.

Mirrors are used to protect and hide the Sun Country, which is ruled by twin sisters. When Holliday College funded an expedition nearby Queen Leila tried to take the opportunity to usurp her sister and take full control of the country, but her plotting was brought to an end by Wonder Woman.

June, 1986.

Trivia/Notes:

The Crisis on Infinite Earths: Absolute Edition (2005) list this as an appearance of Earth-Forty (with the Earth-Two Wonder Woman having similar adventures), while the Essential Wonder Woman Encyclopedia (2010) places them on Earth-One. This means that these events happened with slight variations on all three Earths.
