Nokia phone charges from ambient radio waves

It uses ambient radio wave energy to keep the phone in standby mode. Researchers hope to be able to charge the phone with this technology too. They hope to have it commercially available soon. Which would mean you’d never have to plug in cell phones (or other portable devices) to recharge them.

  1. I’m not sure which is scarier: that we’re constantly bombarded with that much high-frequency energy, or that we waste that so much energy that cell phones and other electronic devices can tap it.

    On the other hand, the uses for recapturing this energy are endless. Currently people with pacemakers (like me) have to have them cut out and replaced an average of every 7 years when the battery dies. They can test and reprogram these little gadgets using wireless technology, but for now there’s no way to recharge them. That means a predictable periodic invasive surgery. Ambient charging would eliminate that!
