The U.S. Defense Advanced Research Projects Agency (DARPA) hopes to roll out battery technology that can self-destruct on command. The agency recently awarded a $4.7 million contract to SRI International to develop a transient power supply that can be triggered to vanish. The contract is part of the DARPA Vanishing Programmable Resources (VAPR) program, which hopes to develop electronic components that can decompose when they are no longer needed. These "vanishing" electronics could self-destruct once the equipment is no longer in use or under the control of U.S. forces.
