Here's a project you might not think of as having a green or sustainable angle to it, until you have need for it. With this scanner you can preserve the information in your magazine collections and books without having to preserve the items themselves, so you can live in a smaller space, a tiny house even.
On Instructables, Daniel Reetz shows how for about $300 you can built your own fairly high speed book scanner. His scanner is built from trash picked wood, acrylic and computer parts along with two digital cameras and other purchased items.
It looks like the project is well beyond the average person, but if you are above average take a look and scan a book.
