Ramar 'admits' herbal fuel a hoax: Ramar Pilai, who had claimed to the world that he had invented herbal fuel, has reportedly admitted to the CBI that he is not making or selling herbal fuel. The CBI, which has been interrogating Pillai since he was arrested on Saturday, has reportedly also obtained "clinching" evidence that he used to buy organic chemicals from the market and sell it as herbal fuel after mixing additives.
