Who needs polluting fossil fuels when we can get energy from the paper? Sony has just introduced a battery that is capable of generating electricity from paper.
It uses an enzyme to break down into glucose which paper is used to generate energy. This method can produce 18Wh of energy from an A4 sheet and certainly seems a great way to recharge devices like mobile phones and portable media players, among others.
It’s a very good invention, but remember to make paper, trees must be cut so that after all this is another innovation that degrades the environment.
