Kinetic energy concept uses ankle power to charge gadgets
It seems that the last time someone made a prototype that channelled kinetic energy into charging gadgets, it turned out to be a massive knee brace that was totally unwearable. Still, there's no harm in envisaging a future where that technology will be suitably efficient to fit into a colourful little ankle band.
This would be particularly useful to me, as I am a famous leg-jiggler who caused at least one Shiny Towers resident to confusedly look at the floor and wonder if we were over a tube line and, if so, how the rumbling reached up to the third floor. Imagine being able to use that to power my iPod and BlackBerry without having to drain the world's resources further. That is my happy thought for the day.
