(FORTUNE Magazine) – Edward Lowe, 69, the man who gave the world Kitty Litter, has started a boot camp for entrepreneurs at his Michigan farm. The campus ain't much: The dorms are in two boxcars that Lowe bought for $4,000 each and hauled into the woods. Nor are the hours: Reveille is at 6 a.m., though Lowe himself rises at 3:30. Says he: ''Entrepreneurs get rolling.'' The fees: It's better than free -- Lowe will give the students a $200 weekly stipend. So far, 11 college students -- six men and five women -- have enrolled for a / ten-week education in such B-school subjects as writing a business plan. Entrepreneurs who've done it compose the faculty. Lowe, who never completed college, will guest-lecture on how to handle lawyers and ad agencies. All this may fall short of the state of Michigan's requirements for an MBA, but that's not what Lowe has in mind. ''This is not an academia deal,'' he says. ''This is gut and heart.''
