The Aqua Liquid cell phone ought to cater to this need, as it features liquid fuel cells technology to help maintain the verdancy of the earth, although it sacrifices efficiency in exchange. Perhaps we should lobby for greener phones instead of handsets that aim to do just about anything and everything. Wish you could go to greater lengths when it comes to keeping the earth green? The Aqua Liquid is full recyclable and is eco-friendly, where the E-Ink display makes sure it sips less power when used and won’t cut you off in the middle of a conversation.
