Olive, an Indian telecom, is releasing a phone that can be powered for a brief period using a single AAA battery. While it still has a main, rechargeable battery, this wonk-tastic phone has polyphonic ringtones, an FM radio, and a calculator! Best of all you can play Bollywood hits on it!
Obviously this is for a much different market than ours and it’s a great idea – except that stuffing a AAA battery in here is only slightly less wasteful than throwing away the internal rechargeable one and buying a new one. I suppose someone, somewhere needs this.
