Nokia Developed Wireless Power-Harvesting Phones

Posted by samzenpus on from the tesla-would-like-a-word-with-you dept.

Al writes "An engineer from Nokia's UK research labs says that the company is developing technology that can harvest ambient electromagnetic radiation to keep a cellphone going. The researcher says that his group is working towards a prototype that could harvest up to 50 milliwatts of power — enough to slowly recharge a phone that is switched off. He says current prototypes can harvest 3 to 5 milliwatts. It will require a wideband receiver capable of capturing signals from between 500 megahertz and 10 gigahertz — a range that encompasses many different radio communication signals. Other researchers have developed devices that can harvest more modest power from select frequencies. A team from Intel previously developed a compact sensor capable of drawing 6 microwatts from a 1.0-megawatt TV antenna 4.1 kilometers away."

    You think the Earth's environment is something of tantamount importance? WE NEED TO STOP THE INSANITY!

    Can't you see?

    This type of technology is starting a race to the impending heat death of the universe!

    Won't somebody think of the childrens childrens childrens childrens childrens childrens childrens childrens children?
