If you still doubt that the next bubble will be green, check out the latest from California. Green and clean technology gigs surged 36% from 1995 to 2008, beating the state's overall 13% job-growth rate for the same period, according to Silicon Valley-based research firm Collaborative Economics. Since California's on the leading edge of this sector, many see it as a sign of things to come for the rest of the country.

As of January 2008, there were only 159,000 green jobs in California, less than 1% of the state's total, following year-over-year growth of 5%. But, during that same period, total jobs in the state dropped 1%, suggesting that jobs in sustainability just might be more sustainable. Though these may seem like small numbers, keep in mind that the green sector job market is twice the size of the state's biotech presence and two-thirds the size of the software industry.

This post is one of several on business heirs apparent. Let us know in the comments whether you think Colin Hanks can live up his father's legacy, and be sure to check out the other heir apparent posts.

I wonder if Tom Hanks ever stops to reflect on how lucky his career has been. I mean, I know this has been said before, but I still can't get over the fact that one of the biggest celebrity thespians of our era first came to prominence on a goofy sitcom called Bosom Buddies. If it wasn't for some species of divine intervention, Tom Hanks would have been just another deep footnote of the '80s. Although some might consider Bachelor Party a classic -- I'm not sure who that would be -- Tom Hanks' actual breakthrough role came in Disney's (NYSE: DIS) Splash (here's a bit of trivia for you: Splash was the first film released by Touchstone Pictures). Years later, he would go on to star in some of the most memorable movies of our time -- Philadelphia, Forrest Gump, Apollo 13, and The Green Mile. Yep, we all know Mr. Tom Hanks.

But have you ever heard of his son, Colin? He was the product of Tom's first marriage to a lady named Samantha Lewes (she unfortunately passed away in 2002). Colin Hanks may not be as famous as his dad, but, according to his page at IMDB, he is an actor in his own right, and has done a lot of television work -- he's worked on Numb3rs, The O.C., and he's been on many episodes of the sci-fi show Roswell. And he's not doing too shabby in the movie business. He's appeared in King Kong, two other movies starring the one and only Jack Black, Orange County and Tenacious D in the Pick of Destiny, and the recent internet thriller Untraceable.
