Korean vendor Samsung’s new solar powered phone is a very less investment if you are looking for a backup handset with unlimited power source. The firm launched the Samsung E 1107 unit, in India. Solar-powered handsets have long been in development, but this is the first to launch commercially. 
An hour’s solar charge will only give enough power for a five- to ten-minute phone call. Still, that will almost certainly improve with time and the Samsung deserves a big green pat on the back for an important first step. An hour of solar charging, gives approximately 5 to 10 minutes of talk time, which means that in order to get 2 hours of talk time you need to keep this handset for a full day in the hot sun. The handset costs you just 60USD[2800INR]. There is no battery charger for mobile phones till now that has any other way to increase the battery levels. The Samsung mobile phone a better product which charges using the freely available solar energy.
The salient features of the handset include FM radio, MP3 ring tones, embedded games and a powerful torch light. The best part is that it comes with mobile tracker system which means your lost handset can be retraced and restored to you.
The disadvantage with this handset is that it could get corrupted and useless soon because the harmful rays can either burn up the screen, along with the internal parts also getting problematic, unless the hardware is real solid and made of something like aluminum or steel. However, the budget price offering cannot give anything other than a fiber or plastic mobile phone.
This exciting technology could lead to huge reductions in energy demand if every cell phone could pull a charge of juice out of thin air. Basically, in theory, two circuits would be capable of receiving and then converting the free energy to an electrical current to charge the battery of a cell phone. This would be enough energy to keep the phone charged in standby mode which is approximately 20 milliwatts; although at first it won’t be enough to charge the phone while in use, or to full battery capacity. The real trick here is to ensure that these circuits use less power than is being received by the phone.
