Betavoltaic Battery: 30 Years Of Power

Imagine a laptop battery that lasted thirty years without needing to be recharged. The betavoltaic battery research funded by the U.S. Air Force Research Laboratory shines a ray of hope.


(Betavoltaic battery)

Although betavoltaic batteries sound nuclear they’re not, they’re neither use fission/fusion or chemical processes to produce energy and so (do not produce any radioactive or hazardous waste). 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 betavoltaic power supply sounds a lot like a Shipstone, from Robert Heinlein's 1982 novel Friday.

...the place was dark as ink...

So whip out your pocket torch, Friday, powered with its own tiny lifetime Shipstone, and search.
