Sounds interesting. However, I did notice that the company specializes in e-ink signs, not books. They do produce a book product (NUUT), but this announcement applies to their sign product (ink-in-motion).
Perhaps an electrical guru can help us interpret this? How much power would be needed to drive a full ebook device: processor, flash and sd memory, display and other components? How big would a solar panel need to be to deliver this much power?
