Researchers at Duke University have created a device that collects stray energy from Wi-Fi and and other wireless signals and converts it into electricity that can charge as efficiently as solar cells.

A Duke University grad student has come up with a way to double, or more, battery life in Wi-Fi devices, without any changes needed on the device itself. Essentially, the technique regulates how long and when client radios sleep, so that data transfers can be scheduled more efficiently.
Data center managers are well versed in distributing power efficiently to physical servers. But the proliferation of virtualization, with multiple virtual machines and applications running on a single piece of hardware, has made this task a lot more complicated.
One of the elements of Android that is often touted over iOS and other mobile platforms is that it is open source. The open nature of Android means that vendors can build on and extend the platform, or that developers are free to create apps unfettered by restrictive rules and approval processes.
