Designer Jasper Hou has come up with a clockwork LED-based lighting design. To activate the lights, you rotate the clockwork part of the light. As the dial unwinds, the energy released is used to power the internal LED lights.
I used to love walkie talkies when I was younger, but it was so frustrating when the batteries ran out so quickly (and when it eventually broke!). The solves the problem of expensive batteries, since the unit is completely rechargeable using a mains adaptor as well as good ol’ hand-crank power.
