The US’ Defence Advanced Research Projects Agency (DARPA) is developing compact radiovoltaic nuclear batteries that convert radiation directly into electricity. The aim is to power devices for decades without recharging, overcoming heat and weight limitations.Learning Outcomes
- Explain the principles of radiovoltaic power generation and compare it with traditional nuclear technologies such as fission reactors and radioisotope thermal generators (RTGs).
- Analyse the technical challenges involved in developing portable nuclear power systems, particularly those related to heat management, radiation damage, and power density.
- Evaluate the potential military and civilian applications of DARPA’s Rads to Watts program, including long-duration energy solutions for satellites, autonomous systems, communications equipment, and remote operations.
