Tuesday night the PBS science program NOVA will feature an Earth Day look at "the Car of the Future." WGBH, the Boston PBS station that produces NOVA sent us an advance copy of the show to take a look at. Tom and Ray Magliozzi, who are perhaps better known to fans of the NPR show Car Talk as Click and Clack, travel the world from Iceland to China and back to their alma mater at MIT. The "Tappet Brothers" are definitely an acquired taste and not everyone is fan of their shtick on the radio show. However, those who have not acquired that taste need not worry as their presence in Car of the Future is actually fairly minimal. John Lithgow does most of the narration tying the various segments together.

For those that are regular readers of our little corner of the web, most of what is discussed in the show will be familiar territory. Nonetheless the show is still a good primer on all of the various technologies that are being worked on including cellulosic biofuels, batteries, plug-in hybrids, weight reduction and more. The guys visit with Amory Lovins at the Rocky Mountain Institute, Martin Eberhard at Tesla (while he was still there), Andrew Frank at UC Davis and plenty of others. During a segment filmed during the introduction of the Chevy Volt last year, Tom and Ray speak with GM VP Energy and Environment Beth Lowery about choice. Keep reading after the jump.

Update: Check your local listings for time, but NOVA typically runs at 8 or 9 pm on most PBS stations.
