Intel Plans for 'Free' energy.

Intel announced last week that it is looking at developing tiny sensors that captures energy from a variety of sources which could be used to power mobile phones and other devices.

The company is researching the technology that would allow the generation of small amounts of charge from sources such as sunlight and body heat. The ultimate aim would be devices that don't need active recharging.

There is already some similar technology on the market, such as watches powered by body heat and movement. But Intel is taking it a step further, including the possibility of getting energy from the radiation emitted from mobile phones and TVs. This Wisp (wireless identification and sensing platform) technology would also enable real-time reporting of the environment without the need for power, which could turn out to be an even more important application.

Don't expect any products soon, though.
