While filming at AltWheels we ran into Click & Clack, the Tappet brothers: hosts of NPR's Car Talk. We asked them how they were enjoying the show, and whether they were prepared to deal with all the new technology coming down the pike. (Part of our Treehugger TV piece.)

John Moore of Boston Clean Air Cabs talks about the challenges and benefits of introducing hybrid vehicles to urban cab fleets. Plus a word from the lucky driver of Boston's first hybrid cab. Shot at AltWheels, footage for our Treehugger TV piece.

Honda's alternative fuel vehicle consultant Barry Carr talks about the compressed natural gas (CNG) Civic that's been brought to retail market in California and NY. Refuel your car at home! Filmed at AltWheels Boston 2006, it's extra material from our Treehugger TV piece.

This vintage microbus has been heavily modded by VW's Electronic Research Lab in Palo Alto, California. It's battery powered, and stuffed with electronic gizmos that for the most part work (but I don't know about the vein-detecting entry system...) This bus would make a sweet ride for 007 on his day off. We shot this at Boston's AltWheels Festival last September, material for a piece we produced for Treehugger TV.
