In their words
“[Power] is the currency of the Moon. But more importantly, in order to sustain a presence on the Moon … you need power not only during when the sun is shining, but to survive the lunar night.”
“[Helium-3] is an extremely rare and valuable resource on Earth. … about 20 to 25 million dollars per kilogram, and it's very difficult to get on Earth.”
