A solar-powered auto-rickshaw - Tuk-Tuk - an initiative of an Indian-origin engineer Naveen Rabelli, turned many heads at Low Carbon Vehicle Exhibition being held in the UK. The refurbished Tuk Tuk , originally a basic auto-rickshaw, was made fuel-free, solar operated and fully electric by Mr Rabelli, an engineer from Hyderabad. He designed the Tuk-Tuk with the help of small fuel efficient companies in India.
