A mechanical engineer, Sounthirajan Kumarasamy from Coimbatore, had his dream come true. He designed a unique engine that utilises hydrogen as a fuel source & releases oxygen. It took him 10 years to develop this first-of-its-kind invention in the world. The eco-friendly engine runs on distilled water. He said the engine would soon be introduced in Japan, but his dream is to introduce it in India, which he hopes to happen soon.
