Wow… I’m so impressed with this news. From U.S. Air Force Research Laboratory, we can hope for a laptop battery that can last 30 years without single recharge. These batteries generates huge amount of power in kinda nuclear style as the main energy source of these batteries are radioistopes. As any high school student can tell you radioactive material goes into continuous transformation while simultaneously emitting beta particles. The scientists claim the emitted beta particles can be transformed into electric energy to power electronic devices such as laptops for years. Though the process sound nuclear, its far from it as the batteries doesn’t use fission/fusion or chemical processes to produce energy. 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.

“Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current.”

The good news, we don’t need to wait for long time to have this reached the market. If all goes well plans are for these cells to reach store shelves in about 2 to 3 years. Great!!!
