Its really fascinating to witness the upcoming technology with old concepts which in return gives more comfort and ease of use. Who would have guessed some company manufacturing Cellphone based on AAA sized battery? and now, Motorola, is in a process to give it's cell phones an ability to squeeze power from the heat of sun rays. Well, it'd be LCD powered Solar panels. It's not a wonder coz we've been using Solar powered Calculator already during our SLC's math exams.
By the way, it is to note that LCD will be turned on and phone will be charging its battery from Solar power. Seems quite a fiction but yeah, it'll soon become reality and needs no power cable to charge.
