Dean Kamen aims to clean water, generate electricity with Slingshot machine

This one has been making the rounds for a little while now (including a recent appearance on The Colbert Report, viewable after the break), but it hasn’t received anything near Segway-like coverage, which is all the more curious given that it’s potentially a far more important device. Dubbed the Slingshot, Dean Kamen’s latest creation promises to do nothing short of producing clean water from virtually any liquid source (without filters) and generate enough electricity to power about 70 energy efficient light bulbs. What’s more, Kamen estimates that the machines would cost between $1,000 and $2,000 which, given the number of people a single one is likely to help, is certainly quite the bargain.

Samsung aiming for water-powered cellphones by 2010

We’ve seen quite a few prototype fuel-cell powered mobile devices, but Samsung’s upping the ante by predicting that we’ll all be running our phones on water by 2010. The company says it’s developed a method to generate hydrogen by exposing water to metal, but the details are a little shaky — we’re guessing it’s similar to the system used in the HydroPak generator, but it’s hard to tell. Still, we’ve got no reason to doubt Samsung’s engineers, who say the system currently provides about 10 hours of use, or about five days of average cell usage, and will eventually allow users to simply top off and go. That’s every traveler’s dream — let’s get this to market, Sammy.

Colo. city’s water is bacteria source

Tuesday, March 25th, 2008 by admin

DENVER - It could be three more weeks before residents of a southern Colorado town can drink water straight from the tap after dozens of cases of salmonella poisoning were linked to municipal water, putting seven people in the hospital.

An analysis indicates the municipal water system in Alamosa is the source of the bacterial outbreak, as suspected, said Ned Calonge, chief medical officer for the state health department.

Gov. Bill Ritter declared an emergency Friday in Alamosa County, activating the National Guard and providing as much as $300,000 for response efforts.

The city and county have also declared emergencies as officials scrambled to provide safe water and disinfect the system with chlorine.

The earliest the city water system could be flushed is Tuesday, and disinfecting it and making sure it is safe could take many days, said James Martin, executive director of the state health department. Water agencies from Denver, Aurora and Fort Collins were helping.

As of Friday, 138 cases of salmonella linked to the outbreak had been reported in people from infancy to age 89, of which 47 were confirmed by lab testing, Calonge said. The conditions of those hospitalized weren’t released.

Alamosa, with about 8,500 residents, gets its water from a deep well system. The water is pure from the aquifer and is not chlorinated.

Investigators are seeking how the system was contaminated. Possibilities include a compromise in a storage tank or cross-contamination with a sewage line, Calonge said.

About 45 businesses are providing enough bottled water to supply residents for several days, in some cases for free, said Hans Kallam, director of the state Division of Emergency Management. Bulk water is also available from East Alamosa, which is not connected to the city system.

Boiling tap water will kill bacteria, but health officials warned that no one should use even boiled tap water once the flushing of the water system begins. People were warned not to give pets tap water, either.

San Luis Valley Regional Medical Center bought in bottled water, and equipment was being sanitized with alcohol, said Chief Operating Officer Henry Garvin.

“It’s becoming much more costly to deliver care, but for patient care it’s not going to be an issue,” Garvin said, who did not have an estimate on the extra costs.

The city had been working to switch to a chlorinated system, but the outbreak is speeding up the timetable, Calonge said.

Only 15 salmonella outbreaks from public water systems were reported from 1971 to 2004, the federal Centers for Disease Control and Prevention said.

Symptoms include diarrhea, fever and stomach cramps that usually go away within a week, although same cases may require hospitalization.
