Do you know that your next mobile phone or laptop could have a continuous power battery that lasts for 30 years without a single recharge. Such great invention was made by Scientists of 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.
The profile of the cell phone battery can be quite small and thin, a porous silicon material is used to collect the hydrogen isotope tritium which is generated in the process. The reaction is non-thermal which means mobile phones, laptops and other small devices will run much cooler than with traditional lithium-ion power batteries. The reason the battery lasts so long is that neutron beta-decay into protons is the world’s most concentrated source of electricity, truly demonstrating Einstein’s theory E=MC2.
The best part about these cells are when they eventually run out of power they are totally inert and non-toxic, so environmentalists need not fear these high tech scientific wonder batteries. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years.
