The Norwegians have a new electric car coming to the United States in 2009 that's got Clark very excited. It's called the TH!NK City and it gets 110 miles on a single charge and goes up to 65 mph. The cost? About 2 cents a mile! And it doesn't eat up foreign imported oil like a gas-engine vehicle.

In other news, a group of researchers in the lab have developed an easy way to take sugar and turn it into a power plant for a hydrogen-powered vehicle. This development is not ready for the mainstream yet, but it's in the works. There are a lot of promising advances that are going to take a while to materialize in the marketplace.

In the meantime, Clark wants to encourage you to look at offbeat transportation alternatives. Washington D.C. has launched a Smartbike program. You pay $40/year for access to bicycles that are strategically placed around town. Users have a code to unlock the bikes and lock them up again at the other end of their commute. It's almost like a Zipcar program for bikes!

Worried about getting too sweaty during your ride? Buy an electric bike for around $600 and it will be no sweat getting around. Clark knows this all sounds kooky, but we need to expand our minds and realize we're not sitting ducks for foreign-oil interests. Christa has long had a fascination with a bicycle that runs on a weed whacker motor. If you Google "weed whacker bicycle," you'll even find videos that detail how to convert your bike.
