IBM scientists in India create a device that could power lights, fans and phone chargers with discarded laptop batteries | IBM Research Blog
By using discarded laptop batteries, we created a device that could power lights, fans and mobile phone chargers. The specific prototype we built was able to provide around 20 Watt-hours of energy. In other words, it can power a 5W DC light bulb for about four hours before running out of charge.

We should think more like them.
