IIT Madras develops solar race car, hybrid rocket engine

IIT Madras students have improved their solar-powered car for the upcoming Bridgestone Solar Power Challenge in Australia. They reduced the car's weight and enhanced its systems, aiming for a top speed of 120 km/h after testing it at 45 km/h. The solar car will compete in a 3,000 km endurance race using solar energy. The solar panels now have 24% efficiency. The team is preparing for test runs with carbon fiber components. Another team, Abhyuday, showcased a hybrid rocket engine at the event. This engine, the first of its kind developed by an Asian student team, will use solid fuel and a liquid oxidizer to lift a 4 kg payload to 10,000 ft.
