Since the book was published (2006), there have been many developments in the automotive world as well as in the general economy that have provided some additional perspective as well as alternative paths. Vehicles that have both internal combustion engines and electric motors with batteries (traditional or plug-in hybrids) may not even end up "recharging America". In fact, it may be precisely the complexity of marrying the internal combustion engine with all its necessary vital parts and the batteries and electric motors that will eventually kill these "almost electric cars"
There are several completely electric cars on different stages of design-production cycle from Tesla Roadster (already produced) to Nissan LEAF (due out in 2011) that are poised to become the next big thing in the automotive world.
If you are considering "Plug-in Hybrids. The Cars That Will Recharge America" by Sherry Boschert, my advice is to wait until the next revision. After all, as the president of the San Francisco Electric Vehicle Association, Sherry is uniquely positioned to see the rise of completely petroleum-free electric cars and write a book about them.
