Dual Purpose

There are technologies that may provide solutions to many problems the world faces, Craig Venter said at The Wall Street Journal's ECO:nomics conference this week. The conference, which is being held in Santa Barbara, Calif., focuses on issues of business and the environment. According to a Digits blog post at the Journal, Venter said reducing industrial inefficiencies and waste is important, particularly in light of a growing global population. In his talk, Venter said he has developed a microbial-based technology that both desalinates water and generates electricity. "We don't need one solution," he said. "We need to change how we produce food, find new ways to clean up water ... or we're going to be facing some tough challenges as we keep adding a billion people every few years."
