NTT DoCoMo Solar Cellphone
Japanese cellphone carrier and supplier NTT DoCoMo says it has developed a uniquely solar-powered cellphone prototype. Using a combination of thin photovoltaic cells on the outer shell and an energy-efficient chipset, the as-yet unnamed phone can run entirely on solar power, escaping the need for batteries altogether. If put into production, the phone would still retain most of the features of a contemporary handset such as Internet access and messaging, according to NTT DoCoMo. The current form also encourages callers to save battery life during idle periods by including a conspicuous power button. While no plans have been announced to ship the phone as-is, the prototype is functionally complete and likely points to future handsets that rely partly or completely on solar energy.
