DOE’s latest fusion energy road map aims to bridge known gaps
The Department of Energy introduced a Fusion Science & Technology (S&T) Roadmap on October 16 as a national “Build–Innovate–Grow” strategy to develop and commercialize fusion energy by the mid-2030s by aligning public investment and private innovation. Hailed by Darío Gil, the DOE’s new undersecretary for science, as bringing “unprecedented coordination across America's fusion enterprise” and advancing President Trump’s January 2025 executive order, on “Unleashing American Energy,” the road map echoes plans issued by the DOE’s Office of Fusion Energy Sciences (FES) in 2023 and 2024, with a new emphasis on the convergence of AI and fusion.
The road map release coincided with other fusion energy events held this week in Washington, D.C., and beyond.

We report the controllable generation of double emulsions for target fabrication using glass capillary microfluidic devices. Instead of a conventional triple-orifice droplet generator, user-friendly glass capillary devices are used to produce micrometer to millimeter-sized water-in-oil-in-water emulsions. The double emulsions have a relatively uniform size distribution with an average outer diameter of 1420 μm. The sizes of the emulsions can also be varied by changing the ratio of the inner, middle, and outer fluids. Increasing the flow rate ratio of the outer fluid to the other fluids [Qo/(Qm+Qi)] from 3 to 11, the outer radii of the emulsions decrease from 1120 to 950 μm. On the other hand, increasing the flow rate ratio of the middle fluid to the inner fluid (Qm/Qi) from 0.7 to 1.6, the aspect ratio of the emulsions increases from 4 to 8. Our experimental values are in good agreement with a simple theoretical model. These results suggest that our present method to control the generation of double emulsions can be used as an alternative approach to fabricate polystyrene targets for future laser fusion experiments.
