Very soon, you won't be complaining about your laptop running low on juice. In fact you probably won't complain about the battery if your laptop packs a betavoltaic battery. Not for 30 years anyway.
If you're geeky and want to understand how it works, you can visit the links below. (You may want to keep your physics textbook within arm's reach.) For the non-geeky crowd, the battery's advantages are listed in English below.
- Small and thin
- 30 Years of Power?
- Non-toxic and environmentally friendly
