Mr. Edison's Kindle

Apparently Thomas Edison had an idea for metal-paged books that had 40,000 pages and weighed about a pound, sort of like a forerunner for e-readers if you squint and tilt your head funny. Still, an interesting read. Included are summaries of such forward-thinking projects as wireless automobile telephones (1913), telenewspapers and electric writers (1928), watch-case phonographs (1936), "magic lantern talkies" (1937), Colorfax (1947), neck-strap TVs (1965), and a bunch of others.
