Darpa commissions development of a radionuclide battery (heise.de)

• DARPA funds development of radioisotope-based power sources.
• Avalanche Energy pivots from fusion research to military power tech.
• Targeting high-density, long-endurance energy for remote operations.

"The US Defense Advanced Research Projects Agency (DARPA) has contracted fusion startup Avalanche Energy to develop a radionuclide battery. Unlike traditional chemical batteries, these units derive power from radioactive decay, offering significant longevity and energy density for remote or specialized applications. This contract represents a pivot for the firm, moving from experimental fusion research to practical power source development. The project underscores the growing military interest in self-sustaining, long-term power solutions for autonomous systems and edge operations."
