The U.S. Department of Energy has approved billions of dollars to technology developers such as Silver Spring and a bunch of utilities to test and deploy smart grid technologies across the country.
While municipal water utilities are required to provide public reports of test results, bottled-water makers are not. (On the other hand, well water, which is found in many rural areas, isn't regulated as water provided by towns and cities is.) So although you may fork over a pretty penny for bottled water, that doesn't mean it's any better than what's coming out of your faucet.
