INDEX Awards: Human-Powered LED Lamp

Hand Powered LED Light

This first product is a brilliant use of green technology. Simply turning a crank provides this LED light with power.

While we can’t expect everyone to turn a crank every time they want to turn on a light, this is an interesting solution to provide power to 3rd world countries with no electrical grid.

And hey, you can always keep one handy for emergencies.
