Preventing battery fires Researchers from Oak Ridge National Laboratory and the University of Rochester developed a method to prevent lithium-ion batteries from catching on fire when damaged. "In a lithium-ion battery, a thin piece of plastic separates the two electrodes," said Gabriel Veith, a research lead at ORNL. "If the battery is damaged and the plastic layer fails, the electrodes can... » read more

Encryption chip A team at MIT developed a new chip to lower the power consumption of public-key cryptography for IoT devices. Software execution of encryption protocols require more energy and memory space than embedded IoT sensors can typically spare, given the need to maximize battery life. The new chip is hardwired to perform public-key encryption and consumes only 1/400 as much power as... » read more

PV technology comparison Joshua J. Romero at the IEEE Spectrum put together an overview of photovoltaic technologies, including the world records for each type of cell, grouped into five broad categories. There is a brief overview of each cell type and some of its trade-offs. He also looks at how fast each technology has made efficiency gains. The most rapid progress is being seen in high... » read more
