Do you know the name of this book?

It was about a kid who made himself photosynthetic.  And that's really the only thing I remember about the book.

There was a good quote in the book.  Something along the lines of "if I told you I could whisper in the ear of somebody in China, would you think I was crazy?  With a phone, I can whisper in the ear of somebody in China."

I probably butchered that quote, but you get the point...

If you know what the name of that book is, please tell me.
