Al Gore, the senior advisor to Google, Apple board member, and former U.S. vice president, has won the Nobel Peace Prize for his crusade on climate change. Sure, there was that documentary. But his finest achievement, I feel, is his work in urination. Besides Apple and Google, Gore also serves as an advisor to Falcon Waterfree Technologies, a company which sells toilets that spare our earth's precious watery resources. They're installed in national parks, the Pentagon, and all sorts of other places. Whenever I unbuckle at one of these Mother-Nature-friendly rest stops, I think of Gore, take a wide stance, and smile.
