Based on four 7-million-kilowatt-hour Controlled Nuclear Fusion power plants, each plant would consume roughly 8.6 kilograms of helium-3 per day. Given the energy requirements of the Primary Stargate, three Controlled Nuclear Fusion power plants would actually be enough to meet its activation needs.
With three plants, daily helium-3 consumption would be 25.8 kilograms.
Based on the density of the Great Qin lunar soil they had mined and brought back, which was roughly 0.8 grams per cubic centimeter, each cubic meter of lunar soil weighed 800 kilograms.
And based on the helium-3 contained in Great Qin lunar soil, roughly 10,000 cubic meters were needed to extract one kilogram of helium-3.
In other words, their previous plan was somewhat unworkable. After considering cost-effectiveness, it simply was not worth it. If they transported the soil back for processing, it would only be enough to activate the Primary Stargate for one day. That was far too difficult.
And what did 10,000 cubic meters mean? It was equivalent to 8,000 tons. How long would current launch rockets need to transport that much material?
When Jiang Yan Hai had considered it before, he had wanted to send integrated refining equipment directly by rocket to the moon in this world for extraction. But at present, progress on that plan was too slow.
Because if they did that, Er Dan's involvement would be indispensable. But after thinking about remote automated control, Jiang Yan Hai decided it would be better to use second-generation Controlled Nuclear Fusion reactors.
That would make extraction directly from seawater much easier and speed up their current progress.
And this was the moon of this world. On Earth's moon, helium-3 density was even lower; it took roughly 30,000 cubic meters to extract one kilogram of helium-3. However, Earth's moon had helium-3-rich concentration zones.
The density
