It's a fact: battery life is one of the more pressing issues that laptop owners have to deal with every day. Some even go so far as to lug along an extra charged battery to avoid running out of juice on the go, while some have to make room in their busy schedules just to plug in their laptop somewhere and have it charged.

Those practices may become the thing of the past, however, if reports of batteries that last for 30 years without charging are true. Apparently, the U.S. Air Force Research Laboratory is now working on one such battery that runs on betavoltaic power.

How does it work? The radioactive material that slowly decays inside the battery emits beta particles which turns into electricity. The decay process is very slow, slow enough for it to run about 30 years without charging. The batteries can be used for electronic devices such as laptops and mobile phones.

Surprisingly, these batteries won't be as large and heavy as most other laptop batteries. Next Energy News supposes that these long-lasting batteries will be small and thin, and will not heat in the same way as conventional batteries do. Can we say goodbye now to burned laps (or laptop explosions)?

This is certainly one very exciting gadget to look forward to. Will we see it in the near future? We sure do hope so.
