Could it be powered by the light from the CD reader laser? Could it then modulate something to look like it is a CD being read? Is there any indication that there is anyone from this company monitoring this list? Thanks jim ----------- [Excuse the cruddy formatting - I'm using Microsoft Outlook Web Access.] I've actually handled these devices (sort of at the level of a colleague saying "Here's something cool - what do you think we could do with it?" The early models have a pair of lithium cells built in (two for balance). The company is looking into other battery technologies as well - there are some paper thin batteries coming out. (It's actually asounding that they can fit their board, batteries included, into the thickness of a CD, but they've done it.) I wonder about induction too - could you put a small magnet in the disk, and use the varying induced fields in the reader mechanism to generate power?
