Now this sounds familiar. Where have I heard read/heard about a battery that would last forever. or an eternal battery?
Why L.Ron Hubbard's secret scripture from Scientology. The story of Xenu is covered in OT III, part of Scientology's secret "Advanced Technology" doctrines taught only to advanced members.
