There sure are lots of automobile choices out there vying for your hard earned dollars. Cars come in all shapes and sizes, and finding the perfect one can be a daunting task for those who are not very well versed in the market. Today, as gas prices continue to climb, choosing the right-sized car for your needs is increasingly important to the pocketbook. A recently-widowed woman who needs to downsize from her current Ford F-150 truck sent a letter to Tom and Ray Magliozzi, better known as Click and Clack, wondering what new vehicle would best suit her needs. The real question: How much power is enough?

Simply put: drive all your options before making a decision. Be sure to consider how many miles will be driven on the highway as opposed to the city and how many people you will regularly be taking with you. For those who drive predominately in the city and alone, the smallest available engine is most likely going to work out just fine, which, incidently, is true for the majority of the population of the United States. Now, need and want are two completely different questions...

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.

The guys that make all the traditionally staid staff at NPR cringe whenever they come on the air will be making an appearance on NOVA this week. Tom and Ray Magliozzi will be going in search of the car of the future on the PBS science show on April 22 (which is, of course, Earth Day). To those of you who listen to NPR on Saturdays, Tom and Ray are more commonly known as the "comedic" mechanics Click and Clack who host Car Talk. Having heard these guys in the past, I'm not sure how much they know about cars of the future.

One interesting aspect of this program is PBS has set up a special section of their website called Open Content. You'll be able to go there and select from 230 raw video clips running 1-3 minutes each that were recorded during the making of the show. The clips will be downloadable so that you can compile your own program by mixing Nova's footage with your own. You can then upload your version of the show and perhaps Nova will put it on the site. At the very least, if you do a re-mix let us know where it is and we'll compile of list of links here on ABG.

Tom and Ray Magliozzi, who host of the popular NPR program Car Talk as "Click and Clack", address the controversial issue of ethanol efficacy. According to a listener's letter,131,000 British thermal units (BTU) are needed to produce a gallon of ethanol. However, that gallon only produces 77,000 BTU of energy. The listener wonders if the 54,000 BTU shortfall per gallon is truly cost-effective compared to gasoline.

The Magliozzi's first point out the difficulty of calculating what constitutes the elements in producing the fuel. Scientists agree that the energy to plant the corn and processing it into starch should be in the equation. They disagree, though, if the energy to manufacture the tractor used in processing corn should be included as well. Also, converting corn into ethanol creates various bi-products such as corn oil. When the energy producing such products are entered into the equation, the shortfall vanishes. Tom also reminds readers that the equation only considers corn as the source of ethanol. Sugar cane, which can also be converted into the fuel and is more energy efficient, can wildly change the figures.
