Short overview of what he does:

He has a wildly popular blog, and he is an affiliate for a few products, most notably, hosting. He makes 30K or more per month, from this one affiliate program.

He sells an ebook, something related to green architecture.

He also builds info sites, with Adsense on them and makes a few thousand from those.

He has a couple of iOS apps I believe, built with outsourcing.

As far as I can see, none of the above is passive or even close to passive (except may be the ebook). He worked hard to get where he is, and still does. He shares much of his numbers - good inspiration if you need some.

Passive does not equal no work. I think the passive comes in after you put in that initial work, creating ebook, adsense sites, etc. and then only needing to devote a minimum of time to maintain that income.
