ECO-FRIENDLY: T. J. David, project coordinator at IIIT- Hyderabad, invented a unique solar crop harvest machine that works entirely on solar energy and has built-in photovoltaic panel of 200 volts. This harvester ensures a high level of power saving by replacing power transmission systems of conventional harvesters. There is also provision for a pedal wheel to make it much more manoeuvrable. The harvester costs Rs.2.5 lakhs compared to the Rs. 15 lakhs to Rs.22 lakhs of a conventional one.
