A remote that doesn't use batteries
According to Tech-On, NEC and Soundpower hope to have a commercial version of the remote ready by 2011.
Unfortunately, this technology probably won't be used in high-end remotes or custom installations any time soon. While button-press remotes are fine for individual devices and small systems, most complicated set-ups are best served by a screen-equipped remote that can use its display to either (in button-equipped remotes) offer many more times the functionality but giving buttons multiple uses through a menu or (in touchscreen remotes) completely replace the buttons altogether. Good luck powering an LCD screen just by tapping it with a finger.
