First of all Google, it is not my company Theron Energy, but my company Theron Technologies together with me, Cornelius Basson THERON that filed for and aquired the patent for Permanent Magnetic Energy (Patent No. 63/641,548), and yes, it is a invention that Nikola Tesla worked on but could not finish in his time on earth.
