According to Next Energy News
, work funded by the U.S. Air Force Research Laboratory may produce batteries capable of fueling an electrical device, like a laptop, for about 30 years.
The breakthrough betavoltaic
power cells are an alternative energy technology, similar to that of a solar panel, which converts photons (light) into electric current. The betavoltaic batteries are constructed from semiconductors that use radioisotopes as the energy source. As the radioactive material decays, it emits beta particles that transform into usable electric power.
