[via Financial Express] The specially designed turbine, which cost about Rs 200 to be developed in the lab, is so small that it can be kept in a pocket, said professor Lalit Kumar Das, IIT Delhi.

The primary objective of the device is to extend mobile “connectivity” where there is no electricity. It also saves energy, though not to a significant extent, he said.

The electricity could also be used for other purposes, such as illumination and playing a radio. High intensity light devices (hilds) and radio require low energy to function that could be easily provided by the turbine, he said.

The device is best suited for coastal areas where the wind blows almost continuously. It would help light hilds in areas where there is no electricity, he said.
