Interesting inventions by an Indian Scientist

He is an Indian Hindu scientist. We respect him. He is creating and sharing knowledge and is not miser in spreading it. He is also patriotic and a good human being. He is NOT a Hindu zionist from RSS, BJP or Bajrang Dal. Those good Indians doing good for humanity and not harming anyone have nothing to fear from Pakistan or Muslims. Dalits, Shudars and untouchabes would also be safe under Muslim protection as they were for 1000 years. It is time that Hindu Brahmin elite and their fanatic Hindu zionist gangs are made to pay for their crimes -- against Hindus and Muslims, Sikhs and Christian as well as Maoists alike
