BENGALURU: After toiling on it for nearly half his life, 80-year-old Paramahamsa Tewari finally received validation for his space generator ­ a super high-efficiency machine that produces power from vacuum A prototype of the machine tested by Kirloskar Electric exhibited 165% efficiency, said Murlidhar Rao, former director of Karnataka Power Corporation (KPCL), assisting Tewari.Through an agreement signed earlier, the Kirloskar group company can now enter into a contract with Tewari to commercialise the machine. Anand Hunnur, vice-president, marketing, Kirloskar Electric, did not respond to calls and text messages from ET.The breakthrough for Tewari, a former director of the Kaiga Atomic Power Station , came last year when his machine achieved an efficiency of 238%, which means it produced 2.38 times the electrical power provided to it initially, making it the first to achieve this. This essentially defies the Law of Conservation of Energy ­ and in the case of electrical generators, Lenz's Law, which forms the basis of mechanics and thermodynamics laws that suggests machines cannot attain over a 100% efficiency.KPCL has deputed a team of engineers to evaluate the machine. "We have reviewed the product. The evaluations and analysis have been submitted to the managing director for the final approval (to use in the Kappatagudda windmill project)," one of the KPCL engineers said, requesting anonymity.The generator requires an initial infusion of power through a battery or AC supply, following which it produces power sustaining itself on electrons in a vacuum, without requiring external supply. "Space is the only reality, and has the potential to produce massive amounts of power if put through right technology," said Tewari, who has applied for an international patent for his device in the US."Power can be provided to rural areas. The problem of rising power con sumption, especially for indus tries, can be solved. The con ventional generator cannot go more than 90%. This one can exceed 200%," he added."To disprove existing theo ries is not easy. Previous theo ries identified space as a source of energy, but no one has acted on it till now," said PR Magheshwaramurthy, a re tired physics professor at Bengaluru-based Raman Research Institute of Technology. "If maybe aided by the mix of theo ry and technology, the concept of more than 100% efficiency may be proved under certain conditions."
