Sergio Marchionne, CEO of Chrysler, said that Chrysler plans to introduce a Fiat in the U.S. powered by natural gas. Bloomberg/Businessweek quotes Marchionne: "Natural gas engines offer a better way to cut emissions because they are cheaper than competing technologies."

Fiat is the leader in Europe in natural gas engines with 80% share of methane powered cars and 55% of light commercial vehicles. Alfredo Altavilla, quoted in Bloomberg/Businessweek said natural gas is a "more affordable solution" as it is less expensive to produce transport and distribute compared with other fuel sources.

Best Buy Inc. (NYSE: BBY) continues to sit atop the consumer electronics universe with its largest competitor (Circuit City) now defunct and mass retailers struggling to keep their consumer electronics categories as beefed up as Best Buy's is. So, with that in mind, what is Best Buy's next trick? How about selling eco-friendly vehicles?

Can you see the place where you buy flat-screen televisions and laptop computers selling scooters and Segways? That's what is going on in 19 Best Buy locations on the west coast already. Add to this Best Buy's roll-out of the Brammo Enertia electric motorcycle this summer and the company may be on to something. After all, it has locations throughout the U.S., something most eco-friendly vehicle dealers would love to have but can't. Is Best Buy the next national vehicle dealer?

Recently I wrote a blog post about some of the nice things Ford Motor Company (NYSE: F) is doing. It was just an overview and the article was cursory at best. A member of our excellent editing staff suggested that I might have readers who want a bit more explanation of just what has happened with Ford's stock market value over the last year. I think that for an even better perspective, I'll need to take you back ... way, way back....

Ford Motor Company's stock value entered this decade at $29.30 (the actual per share value was $53.51 but there's a split adjustment factored in). By the end of 2000 Ford stock had slipped to $23.44. One year later the shares had deflated to $15.95 and by the end of 2002 investors were viewing in amazement a stock value of just $9.58. In 2003 Ford took an upswing and shares ended that year at $16.18. But 2004 ended at $14.80, 2005 nearly halved that value to $7.90, and 2006 is shaping up to finish with Ford Motor Company shares close to today's ending price of $8.13. Two factors that must be considered when viewing this historical trend are: In 2000 Ford's daily share trading volume was in the range of 3,300,000, whereas yesterday's trading volume for Ford was over ten times that much at 30,530,400 shares. How do total share availability and volume traded affect the overall price? I'll honestly tell you, that information is just plain "over my head."
