Science hasn't accepted the concept of Free Energy / Zero Point energy . The main reason behind the non acceptance of this concept is that their fear that this violates Laws of thermodynamics . Over unity machines are those which gave more energy than the energy input . Such machines are not possible according to mainstream science . The concept that efficiency cannot be greater than 100% is due to an incomplete understanding of the properties of space. In the late 1800's Vivekananda wrote a letter to Nicola Tesla .. The letter reads .. “ Mr. Tesla thinks he can demonstrate mathematically that force and matter are reducible to potential energy. I am to go and see him next week to get this new mathematical demonstration. In that case the Vedantic cosmology will be placed on the surest of foundations. I am working a good deal now upon the cosmology and eschatology of the Vedanta. I clearly see their perfect union with modern science, and the elucidation of the one will be followed by that of the other.” – Swami Vivekananda ( Complete Works, VOL. V, Fifth Edition, 1347, p. 77 ) After meetings and conversations with Vivekananda Tesla started using Sanskrit words like Akasha , Prana etc in his writings .. Tesla grabbed the concepts of absolute reality and properties of space from Vedanta and converted them into mathematical form. Tesla was a super-brain understanding spiritual concepts wasn't a problem for him unlike materialist scientists. Tesla discovered Coil Transformer which can transmit power by wireless means .. In the same year he gave a speech at American Institute of Electrical Engineers. “ Ere many generations pass, our machinery will be driven by a power obtainable at any point in the universe. This idea is not novel…We find it in the delightful myth of Antheus, who derives power from the earth; we find it among subtle speculations of one of your splendid mathematicians….Throughout space there is energy. Is this energy static, or kinetic? If static our hopes are in vain; if kinetic – and this we know it is, for certain – then it is a mere question of time when men will succeed in attaching their machinery to the very wheel work of nature.” The usage of terms Akasha and Prana in his writings can be found in the lost journals of Tesla .. “ All perceptible matter comes from a primary substance, or tenuity beyond conception, filling all space, the akasha or luminiferous ether, which is acted upon by the life giving Prana or creative force, calling into existence, in never-ending cycles all things and phenomena. ” – Nikola Tesla, Man’s Greatest Achievement, 1907 Paramahamsa Tewari an Indian inventor who invented a Free Energy device called Reactionless AC Synchronous Generator (RLG) which can produce 238% efficiency ( Over unity ) said the following “ The aakaash is not destructible, it is the primordial absolute substratum that creates cosmic matter and hence the properties of aakaash are not found in the material properties that are in a sense relative. The aakaash is the eternally existent, superfluid reality, for which creation and destruction are inapplicable.” – (Idham thadhakshare parame vyoman. Parame vyoman) – Paramahamsa Tewari, Engineer, Physicist and Inventor. ( Source: http://www.tewari.org/…/SpititualFoundations/SF%20R12702.htm ) The space/ Vacuum / Akasha is filled infinite energy .. Extracting that enegy will solve all energy problems on the planet . This is what many free energy inventors had done and continue to do today .. But most inventions are suppressed because it destroys the Oil monopoly .. Toby Grotz , President of Wireless Engineering says the following about Tesla and Vivekandanda. “ Swami Vivekananda was hopeful that Tesla would be able to show that what we call matter is simply potential energy because that would reconcile the teachings of the Vedas with modern science. The Swami realized that in that case, the Vedantic cosmology (would) be placed on the surest of foundations. Tesla understood the Sanskrit terminology and philosophy and found that it was a good means to describe the physical mechanisms of the universe as seen through his eyes. It would behoove those who would attempt to understand the science behind the inventions of Nikola Tesla to study Sanskrit and Vedic philosophy.” ( Source :http://www.teslasociety.com/tesla_and_swami.htm ) Swami knew we had access to all the powers in the universe .. But most lacked the spiritual wisdom to do it . “ All the powers in the universe are already ours. It is we who have put our hands before our eyes and cry that it is dark. ” – Swami Vivekananda Only scientists who can understand the true nature of reality and the essential phenomena that are non physical in nature can understand all this .. That is why Tesla said “ The day science begins to study non-physical phenomena, it will make more progress in one decade than in all the previous centuries of its existence.”.
