Prediction: the globalists won't let it happen. Energy is a means of control, they cannot allow a near unlimited power source to become available to the masses.
BINGO.
The Templars, the Rosicrucians, the Tutonics, and many other orders knew that the new world existed. That knowledge was a tightly guarded secret back in the middle ages.
Why? Because back in that era, LAND was to the people as ENERGY is today, it is power and control. It is destiny.
With the population of the earth so low, folks could just leave if they did not like something, then they would not have to pay taxes, rent, etc.
That was the base of power for nobility, kings, and the state.
So it is with energy today. We use it for everything, it IS currency, and it IS directly correlated to economic growth. The more energy a nation uses, the more it's economic growth will be.
With free energy, and 3D printing, we could desalinize water, grow an infinite amount of food, clean up the land, water and atmosphere, colonize space, save species, etc. The only limit is the industriousness of the people and the imagination of a nation.
IOW, there would no longer be the control by the world's power elites. It would have the same equalizing effects as the new world had, except whole cultures and peoples would not have to disappear and die of course.
