There are approximately two and a half billion mobile phones in the world, and time in cooperation with conscious dictates us that they all need to be recycled somehow or at least their batteries need to be recycled in order not to cause environmental pollution. There were not many telecom gadgets that where made from 100% safe materials that could be easily recycled without science intensive facilities. Luckily sight of such kind of environmentally friendly gadget has been recently cached. Greenhart Concept cell phone from Sony Ericsson was seen last week in the capital of Denmark on another brand event. Sony Ericsson Greenhart Concept is not a preproduction model as far as we know, it is just probing, first attempts to imagine what our favorite gadgets would look like in a few years, and, of course, gaining experience.Judging by the picture, Sony Ericsson Greenheart Concept looks quite finished and thought-out over all. It is important to mansion that in Greenheart cell phone the most important issue so far is its technical component, features of its materials. Software and design development don't make any problems for Sony Ericsson's production models. So, what is the most special thing about Greenhouse phone? I think it is its battery. It was designed to keep charge as long as possible. Comparison with any trendy mobile phone shows the results. Typical phone spends 37 mW on its standby mode, 30 mW at best. Greenheart Concept uses 3.5 mW. We are not sure how it will influence total battery life because its capacity and type are yet unknown. Device's body and keypad are made of recycled bio-plastic. Used type of "green" plastic can be recycled at one of world's 500 drop-off areas. Even user's guide (as if phone would be sold) will be offered in an HTML source – that will save some trees to clean air, not to be seized for wood.In addition I want say, as far as I understand, a big touch screen with no physical keyboard must be even more efficient in this case. Such form factor requires less materials and easier structure. Anyway Sony Ericsson Greenheart Concept phone is a very first serious environmentally friendly cell phone prototype. Only time will show what will be more appropriate for this new hi-tech area.
