Samsung Crest Solar

If you leave your Samsung E1107 Crest Solar, turned off, under a sunlight of 80,000 Lux for one hour, the solar panel covering its back will charge it for the equivalent of a 5 to 10 minute conversation.

Much less if you use the torch light or FM radio features...

... or if the said phone is baked after a severe sunburn. There's a reason why $100 laptop projects chose the low-tech, man-powered, hand-crank system...

You may also use the airtime for a Fake Call. That's a killer no-killer application : say you are in a cab, and the driver gently caresses a necklace of human ears while staring a lunatic stare at you in the mirror... you can pretend to receive a call, forge a rescue, and live to see another sunrise.

You can even pretend to receive a call from God. That's probably the reason why they dubbed the device "Samsung Crest Guru" in India.

This dual band 900/1800 MHz GSM handset sells for INR 2,799 (about $60). A more advanced European version is expected later this year : touch screen and Bluetooth enabled, the gently curved Blue Earth is made with recycled plastic.
