Helium three is believed to be an excellent nuclear fuel for next generation fusion reactors. As of to day, we have not been able to a to create controlled fusion on on the earth. But may be it will happen in the next te 20 years. So when fusion reactions become fusion reactors become a reality, that's when helium three comes in. And it is found. very rare on earth, but it's found in great abundance in the lunar soil. I thinka doctor, pg obdu kalam, had spoken about this, that the the lunar three is an excellent, is going to be ancellent fuel for future of fusion reactors.
