Way back in 2006, John "Bish" Neuhauser was the poster child of the biodiesel business. The shaggy-looking snow groomer for the Canyons ski area near Park City, Utah, starred in the acclaimed Sundance Film Festival documentary on global warming, "Everything's Cool," in which he made his own biodiesel out of restaurant grease and converted all of the resort's vehicles to run on it. In 2007, however, Neuhauser no longer has to brew his own fuel - he just drives to nearby Salt Lake City, where manufactured soybean biodiesel is now available at seven pumps. "Making it is fun and liberating," he says, "but I'm just too busy."
Can a poisonous plant become a biodiesel hero and help African economies in the process?

When the aspen Ski Company launched its environment division -- a kind of green management team, think tank and consultancy -- it was the first of its kind in the ski industry: an in-house watchdog to prevent the resort from gorging on energy and trampling its fragile ecosystem. Ten years later, the division's director, Auden Schendler, spends at least as much time thinking about saving Aspen as he does about saving its environment. Both, it turns out, are highly vulnerable to climate change.

Auto-racing legend Mario Andretti has met his share of corporate bigwigs over the years - though none, he says, quite as memorable as Patricia Woertz.

And just how frustrating were all those losses at Le Mans?

Trying to invest in ethanol and biofuels today is a bit like Internet investing in the '90s. Most of the publicly traded companies are pint-sized crapshoots, and it's not yet clear whether the early-to-the-game blue chips are pursuing the best strategies. So there are going to be many, many more pets.coms than eBays in agrifuels. More Time Warners than Microsofts. Indeed, many of the venture capitalists bankrolling tomorrow's ethanol IPOs (see "How to Beat the High Cost of Gasoline Forever!") are the same folks who funded the '90s dot-com debacle.

FORGET "WHISKEY RIVER." WILLIE NELSON has a new fuel of choice. He is rollin' toward California "about an hour west of Large Bird, N.M.," on his tour bus. That's apropos, actually, because he's talking about biodiesel, a mix of regular diesel and refined vegetable oil that happens to be the fuel in the bus. Nelson is America's foremost proponent of biodiesel, most visibly as the marketer of a brand called BioWillie. It's for sale at 12 gas stations, the majority in Texas, including his own truck stop, Carl's Corner in Hillsboro, south of Dallas.
