A ROCKING chair that charges your iPad or your iPhone has been unveiled.The iRock from Switzerland-based Micasa Labs generates power from the rocking motion which is turned into power for your portable device. Developers claim if you use iRock for 60 minutes you can recharge an iPad 3 to 35%. You can also recharge any other Apple device.A spokesman says: "iRock is inspired by traditional rocking chairs and we designed it to resemble the classic, proven designed old rocking chairs. What we have added to the design is a generator that transforms the movement into power. We have equipped the iRock with an iPad stand and a set of build in speakers in the back rest."The company says the product explores how furniture can interact with technology and actually support the power for this technology.The iRock is handcrafted out of Swedish pine wood and comes in five different colours. The company says it is under development but is expected to cost about £800.–WO
