You're not profiting from it and you're stating the source, so I think you're fine. Of course IANAL.
Well neither of those things really matter when it comes to determining whether a copyright has been violated. Seems copyright holders will give limited rights to others to copy so long as it's not for profit and proper attribution is given. However, if something is simply copyrited, one may not make copies of the thing for any purpose.
That said, I seriously doubt that Tesla will mind but I don't thing he should do it if he's not comfortable with it. I am really excited for the .pdf version.
