Researchers and space agencies are converging on a class of power sources that could solve one of the most persistent problems in remote sensing: keeping instruments alive for years without ...

Deep space probes and frontline soldiers share a basic problem: once they leave the grid, every watt has to be carried in. That constraint has shaped mission design for decades, from bulky ...

Betavoltaics can store about one million times more energy than other battery like devices but currently cannot release it very quickly. Nano-to-Macro Scale Engineering Applications of Nuclear ...

NASA confirmed that nuclear-micropowered probes (NMPs) using tritium betavoltaic power technology is possible. A new study will raise from a valid concept to a proof of concept experiment.

Batteries that harvest energy from the nuclear decay of isotopes can produce very low levels of current and last for decades without needing to be replaced. A new version of the batteries, called ...

Now a company called Widetronix has developed new betavoltaics that can run for up to 25 years and perhaps power tiny devices in everything from military hardware to smartphone sensors. Nuclear in ...

The current woes of the Boeing Dreamliner and its lithium-ion batteries have put battery technology back in the headlines, but much of the real progress in energy storage is taking place at research ...
