First off, free energy is not free. Much thought and finance must go into tapping this free energy and if you get it, how do you deal with it?
Free energy is different things.
Wind, but of course you have to build windmills to tap it.
Solar, the panels for conversion to electricity are becoming cheaper. There is even a paint you can apply. Great strides have been made in solar power. The expensive solar panels are being replaced with cheaper film and even paint.
Moving water is supposed to be one hundred times more effective than wind. Many new inventions are tapping currents and waves.
Hydrogen and H2O are a part of the free energy family but again, the energy is not free because the research and development of this source is not cheap. New thinking and new machines are required to make it work. In this case, since combustion continues to be involved it’s just a new way to spark an explosion.
The ultimate source of free energy is all around us but again, it will take understanding and the right technology to bring it to bear. We have tagged this source with that of gravity control but as we dig deeper on the subject we have realized that it is more.
The underlying force that runs the universe is the true free energy. But it too is not free.
Many man hours have already been invested in tapping this source of free energy including those of Tesla, Keely, Bearden and Bedini, and more. They call it the zero point. The energy that exists beyond the natural earth and is the source of power that runs the universe. Project Unity taps that source and it is unlimited and doesn’t pollute.
The one thing that keeps coming up that tops them all in free energy is the extraction of power that runs the universe. That’s our focus.

The whole issue of free energy, in relation to the underlying force that drives the universe, is perception.
Is our conceptual perception up to the task?
Our primitive perception of energy is coal, gas, water, fire, wind, tide and nuclear etc., but there is more, much more beyond the limits of our self imposed boundaries.
A limitless supply of energy drives the universe and every aspect of universe, which includes human industry if we choose to go beyond the obvious.
Have you heard of the Keppe motor?
It utilizes the bi-directional, resonant energy which forms the universe.
