10 Fixes For the Planet

The Aptera is not like any vehicle on the road today. It's made with ultra-light (but superstrong) composites, and it has just three wheels to reduce its weight still further. It also has a funky shape—a cross between an insect and a flying saucer—that was designed in the computerized equivalent of a wind tunnel to minimize drag. By next year the car will be available in two models—one hybrid electric and the other purely electric, which can be plugged into any outlet—"even a solar carport," says cofounder Steven Fambro.

Not that a $30,000 two-seater that requires eight hours of recharging will be everyone's ideal car. But Fambro isn't worried. He's presold 1,300 Apteras without spending a dollar on advertising (although he's selling only in California at first to minimize distribution and repair issues). "It's selling itself," he says. "And $100-a-barrel oil doesn't hurt." Are you listening, GM?

8. Stoves for the masses: Inefficient cooking methods are not a trivial problem.

Some 2 billion people in the developing world cook in rudimentary stoves or over open fires. Either way, most of the heat escapes into the air rather than warming the food. Efficient stoves could slash the amount of fuel they use, decreasing emissions and deforestation, too. "A family of five can use three tons of wood a year for cooking," says Columbia University engineer Vijay Modi. "If that family saves one ton of wood per year, that can translate into more than a ton of CO2 saved every year for that family alone." But such stoves have to be cheap, durable and attractive, as well as efficient. A Colorado company called Envirofit International has three new stoves that fit the bill, and the Shell Foundation is investing $25 million to help send 10 million of them to India, Africa and Latin America.

9. New roots for old crops: Perennials could have advantages over annuals.

Modern agriculture, with its nitrogen-based fertilizers, has enabled the Earth's population to swell from 3 billion in 1960 to 6.6 billion today. But agricultural chemicals are contaminating groundwater, and with each plowing and reaping, the world loses millions of tons of fragile topsoil. That's why Wes Jackson's staff at the Land Institute is crossbreeding important crops like corn, wheat, sorghum and sunflowers with wild relatives to create perennials instead of annuals. They are hardier, requiring fewer chemicals, and with the elimination of tilling, he says, "we could take agricultural soil erosion to near zero."

10. Democratize green: Ecofriendly products need to go mainstream.

As long as green products are the exclusive domain of the wealthy, the benefits will be limited. That's why Adam Werbach, global CEO for Saatchi & Saatchi S, is working with major corporations to green their mainstream brands. Take Tide Coldwater, which is formulated to wash clothes best in, well, cold water. "It's a breakthrough product," says Werbach. "If everyone changed from washing laundry in hot water to cold, that alone would meet nearly 8 percent of the United States' Kyoto targets"—that is, if we'd actually signed the protocol.
