CHAMPAIGN, Ill. — Though they be but little, they are fierce. The most powerful batteries on the planet are only a few millimeters in size, yet they pack such a punch that a driver could use a cellphone powered by these batteries to jump-start a dead car battery – and then recharge the phone in the blink of an eye.

Developed by researchers at the University of Illinois at Urbana-Champaign, the new microbatteries out-power even the best supercapacitors and could drive new applications in radio communications and compact electronics.

Led by William P. King, the Bliss Professor of mechanical science and engineering, the researchers published their results in the April 16 issue of Nature Communications.

Rob Wile uses a graph to point out the obvious, the dramatic fall in the cost of solar power generation. In many countries– Italy, Spain, Germany, Portugal — and in parts of the US such as the Southwest, solar is at grid parity. That means it is as inexpensive to build a solar plant as a gas or coal one.

The 2011 accident at the Fukushima Daiichi nuclear power plant was preventable. The Great East Japan earthquake and the tsunami that followed it were unprecedented events in recent history, but they were not altogether unforeseeable. Stronger regulation across the nuclear power industry could have prevented many of the worst outcomes at Fukushima Daiichi and will be needed to prevent future accidents.

In a new FAS issue brief, Dr. Charles Ferguson and Mr. Mark Jansson review some of the major problems leading up to the accident including the lack of regulation of the nuclear power industry and slow updates to safety requirements, such as using probabilistic safety assessment (PSA) methods to  improve accident management plans.
