Cell Phones Powered By Conversations

Posted by CmdrTaco on from the yakkity-yak dept.

disco_tracy sent in a story about some fancy new power technology designed to tap energy from sound waves. Although the cell phone concept grabs the headline, they also talk about harvesting noise from traffic.

    With our state of infrastructure, that much supply would overload the whole thing.

    If only we could harvest energy from articles about operating multi-watt devices from nanowatt energy sources, all of the world's energy problems would be solved.

  3. People use cell phones for conversations? by Haeleth · · Score: 2, Insightful

    Cell phones are for apps, or texting. I didn't realise anyone used them to talk any more, except for members of an evil secret society dedicated to inflicting pain on users of public transport.

    Many would consider it to be recovering some bit of the peace and quiet the passing cars despoil.

    Ridiculous. Phones need about a watt. If you SHOUT into a microphone, you will maybe generate 50 millivolts across 600 ohms, or (E^2/R) about FIVE BLEEPIN MICROWATTS.

    We're a good five powers of ten below what is needed.

    Doesn't anybody do math anymore?
