Summary:

- Researchers have developed a new type of battery that can generate electricity from nuclear waste. The battery uses radioactive isotopes found in nuclear waste as a power source, converting the energy from radioactive decay into electrical current.

- This "betavoltaic" battery is made of a semiconductor material that can capture the energy of beta particles emitted by the radioactive isotopes. The battery is designed to be long-lasting, with a potential lifespan of up to 28 years.

- The development of this nuclear waste battery could provide a way to safely and effectively utilize nuclear waste, turning it into a useful energy source instead of just storing it. This technology has potential applications in remote or off-grid locations where conventional power sources are not available.
