As some readers know, I’ve had a Toyota Prius hybrid since June 2004. It’s easily the best car I’ve ever owned, as well as having very low emissions (104 gm/km) and reasonable fuel economy. Tech Review has an interesting Flash-based exposition of how it works. It’s a fantastically complex piece of engineering — so much so that I’m sometimes amazed, not that it works so flawlessly, but that it works at all.
