Bipartisan commission report urges national fusion strategy
In the report Fusion Forward: Powering America’s Future issued earlier this month by the Special Competitive Studies Project’s (SCSP) Commission on the Scaling of Fusion Energy, it warns that the United States is on the verge of losing the fusion power race to China.
Noting that China has invested at least $6.5 billion in its fusion enterprise since 2023, almost three times the funding received by the U.S. Department of Energy’s fusion program over the same period, the commission report urges the U.S. government to prioritize the rapid commercialization of fusion energy to secure U.S. national security and restore American energy leadership.
SCSP is a nonpartisan, nonprofit initiative making recommendations to strengthen America’s long-term competitiveness in emerging technologies. Launched in fall 2024, the 13-member commission is led by Sens. Maria Cantwell (D., Wash.) and Jim Risch (R., Idaho), along with SCSP president and commission co-chair Ylli Bajraktari.

Two-photon polymerization (2PP) offers an attractive option for direct writing micron- to millimeter-sized laser target components that support high-energy-density plasma physics research. 2PP was used to deterministically print a number of common targetlike structures including tubes, spatially periodic Rayleigh-Taylor–like surfaces, and low-density foams. The structures were printed using commercially available acrylic photoresins. The elemental compositions are reported for comparison with other polymers used for making target components. A number of foamlike structures ranging in size from tens to hundreds of microns and varying in density from 600 to 60 mg/cm3 were readily printed in times ranging from several seconds to a few hours depending on the size. In addition, direct printing was demonstrated to fabricate graded-density foam comprising 12 individual layers with a vertical density gradient of 600 to 80 mg/cm3. Control of shrinkage and deformation during development and subsequent drying remains a challenge for certain structures and a focus of ongoing research.
