Dunham Barney wants to keep failing farms from lying fallow or becoming parking lots. Farmvest Inc., of Simsbury, Conn., offers one-stop shopping people who want to buy a farm. It locates the land, plans what crops to raise, and finds people to manage the farm. "We don't look at it as a vacation home," says Barney. "We look at it as a small business that is also a vacation home."

Barry Wax wanted to start a chili business to tap the boom in specialty foods, but he couldn't find a kitchen to use. Figuring that other entrepreneurs might also need a kitchen, he built one himself -- a big one, 8,100 square feet. Now he rents out cooking space at $27 an hour. In its first year, Kitchen Privileges, of Alexandria, Va., pulled in more than $100,000 from customers large and small, including Campbell Soup Co. and D.C. Desserts Inc., a fledgling wholesaler of baked goods. And, yes, Wax does use his kitchen to make chili.

The ATM system would feature three-seat cars run by computers.

Can an American company win a niche in the personal stereo business?
