Seeing the sharp rise in sales of smartphones including the iPhone, it was only a matter of time before these battery-charging concept devices surface. First mentioned was the handgrip charger and now a swing charger with an added bonus of having your golf swing analyzed. I think we really should think of other ways to harness our own energy because now being physically active would be: 1) enjoyable, 2) energy saving (reduces carbon footprint), 3) money saving (electrical chargers), and even ....get this....4) healthy. The potential to harness kinetic energy into stored electrical energy is not new, and a while back there was a dance floor concept from the Netherlands (Sustainable Dance Club) that proposed using technology to store the energy created by the moving dancers in a night club.
This fall they just opened Club WATT in Rotterdam an this is how the Sustainable Dance Floor works:
The dance floor converts the movement of the dancing crowd into electricity and uses this power to change the appearance of the surface of the floor. For the first time the crowd becomes an energy source that can contribute to power a club. The movement of the clubbers on the dance floor is captured to generate electricity. This electricity is used to create interaction using LED lights and smart materials in the floor. The DJ and the clubbers will be challenged to reach the maximum energy level possible. Every person is able to produce 2-20 Watt, depending on people’s weight and activity.
Dance on, Swing on, just move my friends! It's all good!
