Samsung has launched its (and the world's) first solar-powered cell phone, which it calls the Solar Guru.
The phone will allow five to 10 minutes of talk time per hour of solar charging, with a full charge expected to take 10 to 14 hours. The phone can also be charged using the traditional method of plugging it into an electric outlet. Most people will likely use the conventional method to charge it, and then allow the solar panels to "top it off" during the day.
The phone was designed for India, the world's fastest growing cell phone market. Samsung will launch the phone in Europe, Asia, the Middle East, and Latin America later this month.
The company has not yet made plans to launch the phone in the United States and may opt instead to wait to release the more powerful solar-powered Blue Earth cell phone that is expected by the end of the year.
