    A team of computer scientists and electrical engineers at the University of Washington has invented a cellphone that requires no batteries and harvests power from either ambient radio signals or light. The device is described in a paper published in the Proceedings of the Association for Computing Machinery on Interactive, Mobile, Wearable and Ubiquitous Technologies.

    “We’ve built what we believe is the first functioning cellphone that consumes almost zero power,” said co-author Dr. Shyam Gollakota, from the Paul G. Allen School of Computer Science & Engineering at the University of Washington.

    If there is not a consensus of all scientists that this is possible then it's a fake invention.

    Get with the times: we need a coal-powered cellphone to help with all those new jobs in coal.
