Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.

I think this is crazy or maybe not, it save a lot and extremely lot of electricity. Imagine that? you can play your favorite game or online wherever you want without worrying about electric supply.
