The designer states:
I was looking for opportunities to generate energy through activities we naturally do. The final result is a rocking chair that enables the user to experience production and consumption of electricity in a gentle and rewarding way... Complexity is covered by simplicity. Advanced nano-dynamo technology which is built in to the skids of the chair and more efficient light sources such as the newly developed OLED generation makes it possible to build a rocking chair with a reading lamp running on electricity generated from the rocking motion. During daylight the energy gets stored in a battery pack... To have a drastic reduction of consumption the big challenge will be to make consuming less feel like getting more."Make consuming less feel like getting more" -- what a succinct way of putting it. It is definitely true that putting energy generation into part of the experience would accomplish efficiency without feeling like we're sacrificing anything.
