Small nuclear waste batteries could fuel drones for 30 years via trickle charging, making Spiderweb scenario a permanent…
- Nuclear waste may become fuel for decades-long autonomous operations worldwide
- DARPA wants batteries delivering power continuously for up to 30 years
- Project Omega is converting radiation directly into usable electrical energy efficiently
Scientists working with a United States defense programme are developing compact nuclear batteries intended to supply electricity continuously for several decades.
The effort revolves around radioisotope power systems that convert radiation directly into electricity instead of storing energy through chemical reactions.
Developers believe these lightweight devices could eventually keep drones, satellites, and remote equipment operating without conventional battery replacements for years.
Nuclear waste becomes fuel for decades of uninterrupted power
The programme falls under DARPA's "Rads to Watts" initiative, which seeks compact energy sources delivering high energy density and longevity.
A recent $3.37 million award supports development of a proof-of-concept device producing more than 10 watts per kilogram.
One participant in the programme, Project Omega, is developing...
