The very first thing that strikes our mind whenever any of the gadget stops working is checking the batteries. If you feel you gotta change the batteries, you get the new ones and throw away the old ones! What if I say, you can reuse the batteries? reNEW by Tracy Subisak, Donn Koh and Herlinda lets you do so. Charge your old batteries and use them, its as simple as that. What’s remarkable about the reNEW is that its solar powered. Yes, it sucks juice from the sun to recharge your batteries. A neat decorative frame hangs on your window (via the suction cup) or sits smartly on a table and powers up your batteries naturally.
