Replacing treatment plants that use too much power, and 19th-century networks of leaky pipes

Our water infrastructure is older than our roads and power grid, with many pipes sitting in trenches dug by hand in the 1800s. In parts of the Northeast, up to 50 percent of our clean water leaks into the ground between the treatment center and the tap. Across the country, we lose an average of seven billion gallons of drinking water a day to leaks—and we have an 800,000-mile network of pipes that needs constant monitoring and repair. We also use far too much energy treating all our water, regardless of its end use, and piping it long distances. Besides fixing up the nation's pipes, the future of water is cleaning only what we need.
The World Health Organization estimates that around one sixth of the world lacks access to clean drinking water. Since those billion people are also the poorest people in the world, water purification techniques need to be cheap to help those most in need. Since it activates under plain visible light, this new water-purifying photocatalyst may help bring purer water to the world's neediest people.
Oh, Japan, you never cease to amaze. From the country that brought you water powered jetpacks, robots that make dinner and tentacles that do...other things, comes a floating UFO that will dutifully clean Osaka's public waterways.

"Let's run it through from the top. This is going downhill."
Dean Kamen is standing on a six-inch riser in an almost empty room in the basement of Westwind, his 32,000-square-foot house in Bedford, New Hampshire, trying to get this thing right. It's crunch time for FIRST, the high-school robotics competition Kamen founded two decades ago in an effort to get kids jazzed about engineering, to make science as sexy as sports. (FIRST = For Inspiration and Recognition of Science and Technology.)
In less than a month, 42,000 students on 1,700 teams will gather at 43 regional championships to showcase the ball-throwing 'bots that each team has spent six weeks assembling in novel ways from nearly identical boxes of parts. At stake -- besides glory -- is $9 million in scholarships.
When you’re getting ready to honeymoon in Thailand, issues like water purity suddenly become more relevant. So, my fiancé and I got ridiculously excited about the latest purification technology from Hyrdro-Photon. The SteriPEN Journey LCD uses ultraviolet light to kill 99.9999% of bacteria, 99.99% of viruses and (only?) 99.9% of protozoa. Just stick the wand into a water bottle, push the button, wait a minute or so, and drink.
