Tata Swach

Ratan Tata was once inspired to build a cheap car when he saw a family of four balanced on a bicycle in his native India. Now that the Tata Nano "people's car" is a reality, the business tycoon has unveiled an even more useful product for India and the world. Globally, over a billion people do not have daily access to safe drinking water. The types of water delivery systems we use are prohibitively expensive for many countries. Around 380,000 children in India alone will die this year from diarrhea, mainly caused by the water they consume. An estimated 85% of people in India do not filter their water before drinking. If there were some way to make filtering easy and affordable for them, it would prevent many cases of illness due to waterborne pathogens.

100tataTata Chemicals, a division of Ratan Tata's business empire, has unveiled their latest gadget, a water filter called the Tata Swach. The technology isn't all that complicated. The Tata Swach uses rice husk ash (a product very abundant in India) coated with silver nanoparticles to filter microbes from the water. Rice husk ash has been used for centuries to clean teeth. Now it can clean water to be used for cleaning teeth. The advantages of the Tata Swach include the fact that it needs no electricity. India has 400 million people who are not connected to the electrical grid, and those tend to be the same people who aren't served by a water system. The Tata Swach unit hold 9.5 liters at a time and will clean 3,000 liters of water on one filter cartridge, enough to last a family of five about a month.

The Tata Swach will sell for about £10 each, or a thousand rupees. Replacement filters will be about 30 rupees.

How to Remove Dents From Your Car Without Doing Further Damage

Car dents aren't pretty, and DIY methods for getting rid of them can leave entirely new eyesores in their place. In The Know Innovation has spotted a tool that erases unsightly dents without damaging your vehicle's paint job—no trip to the auto body shop required.

The Sealey RE101 Air Suction Dent Puller is a tool that attaches to your vehicle. To use it, stick the suction cup over the dented area and and open the air valve on the handle to seal it tight. A few pumps of the slide hammer are enough to restore your car to its original, dent-free glory.

There are plenty of at-home remedies out there for minor car dents, some of which involve boiling water, hair dryers, and dry ice. While it's always best to get your car looked at by a professional after any type of accident, especially if the damage is covered by your insurance, a dent puller at least won't do any additional harm to your vehicle (or your hands).

You can order a Sealey Dent Puller of your own online for $166.

The Most Popular Infomercial Product in Each State

You don't have to pay $19.95 plus shipping and handling to discover the most popular infomercial product in each state: AT&T retailer All Home Connections is giving that information away for free via a handy map.

The map was compiled by cross-referencing the top-grossing infomercial products of all time with Google Trends search interest from the past calendar year. So, which crazy products do people order most from their TVs?

Folks in Arizona know that it's too hot there to wear layers; that's why they invest in the Cami Secret—a clip-on, mock top that gives them the look of a camisole without all the added fabric. No-nonsense New Yorkers are protecting themselves from identity theft with the RFID-blocking Aluma wallet. Delaware's priorities are all sorted out, because tons of its residents are still riding the Snuggie wave. Meanwhile, Vermont has figured out that Pajama Jeans are the way to go—because who needs real pants?

Unsurprisingly, the most popular product in many states has to do with fitness and weight loss, because when you're watching TV late enough to start seeing infomercials, you're probably also thinking to yourself: "I need to get my life together. I should get in shape." Seven states—Colorado, Idaho, Kentucky, Montana, Nebraska, Utah, and Wisconsin—have invested in the P90X home fitness system, while West Virginia and Arkansas prefer the gentler workout provided by the Shake Weight. The ThighMaster is still a thing in Illinois and Washington, while Total Gym and Bowflex were favored by South Dakota and Wyoming, respectively. 

Kitchen items are clearly another category ripe for impulse-buying: Alabama and North Dakota are all over the George Forman Grill; Alaska and Rhode Island are mixing things up with the Magic Bullet; and Floridians must be using their Slice-o-matics to chop up limes for their poolside margaritas.

Cleaning products like OxiClean (D.C. and Hawaii), Sani Sticks (North Carolina), and the infamous ShamWow (which claims the loyalty of Mainers) are also popular, but it's Proactiv that turned out to be the big winner. The beloved skin care system claimed the top spot in eight states—California, Mississippi, Nevada, New Mexico, Oklahoma, Oregon, Tennessee, and Texas—making it the most popular item on the map.
