Australian researchers have figured out a way to harness the energy we use while typing to power a laptop. Using piezoelectricity, this method works in a similar way to cigarette lighters that create a spark by striking a piezoelectric crystal. […] The idea of an everlasting battery is mind-boggling. Scientists are also looking into ways to power touchscreen devices with piezoelectric film, putting all that energetic finger-swiping to good use.
