Swiss teacher drives around globe in solar car

Swiss school teacher Louis Palmer takes his homemade solar powered car on a trip around the world just because he could.

He's Swiss so why not? And he calls it a solar taxi because so many people want to ride along.

This video from The Associated Press has been around a couple of years but it still offers a look at zero fossil-fuel travel and the possibility of not having to plug in. "Technology is here today," Palmer says.

Solar technology is improving each year with panels getting increasingly efficient. Perhaps at some point electric cars or plug-in hybrids will offer integrated solar to enable greater range.
