We have abundant cleaner and more efficient forms of energy in our environment. In order to extract these forms of energy, we need to understand them better.
During the past one hundred years, many scientists and inventors, such as Nikola Tesla, Tariel Kapanadze, John Searl, and Stanley Meyer, etc., have performed experiments to prove the existence of such energy sources and some of them have produced prototypes that can actually extract the energy, though they could not explain where the energy come from.
So the key to start to understand and utilize the “hidden” energy sources is to expand our knowledge about our world and our reality. Maybe you want to explore the “Helical Motion” first, because it will show clearly that our planet, the Solar System, the Milkyway Galaxy, and the entire Universe are in constant motion, or some might call it “perpetual motion”. If we can identify the source of the forces behind such motions, then we can, probably, harvest unlimited stream of energy.
You can start the understanding by watching the following movie by Forster Gamble:
