MIT physicist Marin Soljacic is planning a device that will recharge your Ipod, cell phone, digital camera wirelessly. The idea is to carefully design a magnetic field (wow! you'd better be careful about where you place your computer, disks, thumbdrive!), that will reach around a 10-15 foot radius. You leave the electronic gadget in that zone and it will recharge automatically. No more plug-ins! I was reminded of this when I passed a cellphone charging in a library outlet this morning. Sadly, this terrific idea probably won't see the shelves for a while. (Read the full story from Boston Globe in the title link above).
