So what happens to entrepreneurs with risky, unproven, but potentially world-changing ideas in areas like zero-carbon energy or growing replacement human organs? If it weren't for an MIT-born venture firm called The Engine and a tiny handful of other venture firms tackling "Tough Tech," they'd probably never get their ideas to market.
