The dialogue that resulted was unusual, in part because of the players present. Lane Genatowski, senior advisor to the Under Secretary for Science at the US Department of Energy (now Director of the Advanced Research Projects Agency ARPA-E, which promotes and funds energy innovation), delivered a keynote address. Interactive panels included representatives of multiple sectors, ranging from ARPA-E and the Princeton Plasma Physics Laboratory, to investors and philanthropists. In addition, the meeting featured private sector companies working to make fusion a commercial reality.
Three themes emerged: (1) Status updates on the practical feasibility of fusion, across a range of technologies; (2) Fusion economics: R&D cost and return on investment, projected costs per kilowatt-hour, investment sources, and best uses of government funding; and (3) Communication: how best to articulate the shared goals of fusion to the public and other stakeholders across a broad range of enterprises, some of which compete with one another for limited funding.
Given the range of participants, one might have expected the meeting to devolve into competitive arguments over which technology or sector deserved the most support, or which had the greatest chance of success. By contrast, discussions were mutually supportive. ITER, the giant in the room in the sense of both funding and physical size, was repeatedly praised as a point of converging research that would benefit all concerned. Much of the cross-sector and cross-project dialogue centred on how to align diverse objectives and activities to optimize the pursuit of common goals, such as public awareness, safety regulation, enabling technologies and, ultimately, commercialization.
