The Defense Advanced Research Projects Agency (DARPA) is soliciting innovative proposals in exploring and implementing mechanisms that amplify and increase the rates of nuclear fusion reactions in solids at and near room temperature. Proposed research should investigate innovative approaches that enable revolutionary advances in science, devices, or systems. Specifically excluded is research primarily resulting in evolutionary improvements to the existing state of practice.
