Are there better methods that don't require the user to have immediate access to electricity?

  Even the real poor ( < $2 per day) generally have access to charging simple electronic devices. I'd guess those who don't are not likely going to be able to read braille or have access to many books, let alone books in their language in braille. I don't see electricity access as being the issue.

    Well I was thinking of personal experiences and maybe others like to read emergency signs in buildings when power may be out, menus, or read a book outside by the lake. I would not want to rely on electricity to be able to read, it doesn't have to do with poverty.
