Solar-Powered Phones Still Some Time Away, Nokia Says (Mobiledia)
Solar-powered cell phones are possible, but still have a long way to go before
batteries won't be needed, according to Nokia, tempering expectations of green
technology.
The solar-powered phones under development by Nokia can gather enough energy
to keep the phone charged on standby, but don't have much talking or texting
time, according to a study conducted by the Finnish company.
The cell phone maker reported better results when people carried the phone
around outdoors in a holster around the neck, but "that isn't the most stylish
or convenient arrangement, and another solution is needed."
Nokia's findings dampen hopes slightly that solar power is a viable energy
solution for smartphones, as other device makers ramp up look into the
sustainable technology.
Samsung Electronics and LG Electronics both introduced smartphones with a
solar panel on the back cover in 2009, but the technology still isn't
mainstream.
Meanwhile, last year, Apple sought patents for solar-powered phones, which
would embed solar cells into displays instead of in the back of the phone,
solving the problem of phones that can't get enough sunshine to charge them.

developed enough to be widely adopted. ...
