Help me get smarter about SmartMeters

We've had PG&E SmartMeters installed at our building for awhile, and our landlord is very concerned about the health risks and surveillance risks he believes they pose. He's sent us a bunch of "literature" to read and it all reads like wackadoodle conspiracy theories with no basis in science, as does everything else I've found online. As easy as it is to just roll my eyes and dismiss his concerns, I feel like I should make a good faith attempt to discover if there's really anything to be concerned about. Are there any good, reality-based reasons to be anti-SmartMeter? Any science-based studies from reliable sources on their safety? Any well-thought-out articles on the subject that don't include the phrases "molecular earthquakes" or "like hundreds of cell phones being on at the same time"? Help a skeptic out!

Press Button to Cross

How does the button on the pedestrian crossing lights work? Does it actually send some sort of signal to the traffic lights, or is it just a psychological thing? It seems rather random timing-wise.

Learning about electricity, the bright and colorful but not completely dumbed-down way?

I'm looking for a book that teaches electricity well. The Mims book definitely doesn't cut it - I want something more along the lines of "The Way Things Work" in clarity and accessibility, but I still want it to actually teach the underlying math; i.e., I want it to show me the material in pictures and equations.
