Readers living in the UK might not be too concerned about yet another solar-powered gadget, but for those of us in the Far East, the latest mobile phone to go on sale in China has a distinct appeal.
The £250 S116 handset from Chinese firm Hi-Tech Wealth and first seen as a prototype at CeBIT this year is a mostly average phone except for its claim to being the world's first solar-powered mobile. Moreover, the company's claims make it sound like they've managed to get some impressive mileage out of those little solar panels.
After just an hour of direct sunshine the S116 has enough power for 40 minutes of talk time - that may not sound like much, but remember the solar juicing is in addition to regular AC charging. It's also a slight improvement over what was claimed in pre-production. A full sun-powered charge takes 12 hours, so a hand crank like this one might be a wise addition.
Like a desktop calculator, the phone can also draw enough power for a slow battery charge when indoors - apparently, even candlelight is enough to get things moving. Other specs - if you fancy popping over to China for one of these green gadgets - include dual-band GSM (900/1800MHz), MP3 playback and a 1.3-megapixel camera.
