Wanted to get these photos up today after the fun event at work - Google went ahead and converted a fleet of 100 Priuses to PHEV! They plug nicely into the solar panels they've recently put up over the parking lot, so the electricity delivery couldn't be more efficient - or clean.

One other thing about these photos - they're taken with my crappy cellphone camera, which has no zoom feature - so when it looks like I'm standing right in front of the founders of Google - that's because I'm standing right in front of them. They're just that open about access at work, despite their fame. Very cool.
I asked the guys who did the mods and bought the fleet etc a lot of questions so if you guys have any questions, ask away! I'll pass on the details I gathered at the event.
