Technology helps in Kenya – Electricity from dance!

This is a cool story about how technology could help in Kenya and other countries where music is alive but electricity isn’t. In Kenya about 75% of people do not have access to electricity. But they love their music and dance.

So someone has invented a musical shaker called the Spark. As it is shaken the beads not only make noise but also charge a battery. 12 minutes of shaking can then run a light bulb for an hour via a USB port. Or the charge can be used for phone charging or other things too. How good is that?

A less heartwarming aspect of the kinetic energy technology is that the armies are trialing the recharging of batteries for all their soldiers’ weapons and other “toys” from movement of the soldier’s boots.
