Scientists from Indian Institute of Technology, Bombay, find a way to convert undesirable heat energy from electronic devices to electricity and reconverting this into electricity using the concept of thermoelectric effect - a physical phenomenon where a difference in the temperature between two contacts leads to a difference in the voltage, and hence flow of electricity.
Researchers from IISST used simple polymethyl methacrylate (PMMA) to partially correct a turbulent laser beam and restore its statistical order.
