Not sure what You mean by "grow up enough to never have war." The psychopaths in control (by virtue of money) are the Ones who create manufactured wars. Most of Humanity would not be interested in war, and especially when We are all living richly (by virtue of eliminating the psychopath-promoting tool called "money").

And... It is the psychopaths who presently control the free energy tech, the Ones who create the wars. That tech belongs to all of Us, but is avidly hidden and suppressed.

And....... Electrogravitics IS abundant, clean, and continuous.
