I was reading the comments and someone asked the author about the energy invention he was talking about:

"Since I signed an NDA, I’m not able to give you details. But what I will say is that I’ve looked at hundreds of energy related inventions over the years and none have the potential of this one. Its quite obvious how it works, and operates silently inside a container without the need for any external power, water, or other inputs. There is no pollution. And the best part is that it serves as a mass energy storage system, efficiently storing power from one day to the next."
