You don't need to pay for cable TV

You might not know it, but you can watch HDTV with an antenna.
By Dan Schointuch | Jun 30, 2010

Over 99% of U.S. TV households can receive at least one local station over the air, while 89% can watch five or more. The picture is perfectly clear thanks to the switch to digital TV completed on June 12, 2009. You’ll either see a crisp, beautiful image or no image at all (static is a thing of the past). And the best part? All your favorite programming will still be in HD.

HDTV is more expensive for local stations to produce, so it’s common to see a station broadcast in regular standard definition during the day, but switch their signal to high definition for prime time. So while the local news may not be in HD, your favorite shows like Glee, America’s Got Talent, and The Bachelorette will be.

Of course, you will need an antenna to make this work, but your HDTV will also have to have an “HDTV tuner” built in. This is sometimes referred to as “integrated HDTV”. If not, you’ll need to buy a separate HDTV tuner that connects your existing HDTV to an antenna. To check, you may have to consult your HDTV’s manual, do a search online, or contact the manufacturer.

AntennaWeb, a site provided by the Consumer Electronics Association (CEA) and the National Association of Broadcasters (NAB), will show you exactly where to point your antenna for the best reception at your address. It will also let you see which stations are broadcasting over the air in your area. There may be more than you think.

Thousands of E-books: Free

Thousands of E-books: Free

By Stacy Johnson



You know e-books have arrived when the President of the Unites States is writing one.

On Tuesday, Nov. 16, President Obama’s third book debuts. But unlike his previous two, Dreams from My Father (1995) and Audacity of Hope ( 2006 ), this one will be also available as a digital download. Called Of Thee I Sing: A Letter to My Daughters, it’s a children’s book about “13 groundbreaking Americans and the ideals that have shaped our nation.”

But the book itself is part of a trend shaping our nation. E-books are no longer high-tech innovations for early adopters. This summer, Amazon.com announced that it started selling more e-books than hardcovers – 143 e-books for every 100 hardcovers. And by the end of 2011, Amazon says its e-books sales will eclipse paperbacks.

But e-books are not only reshaping the way we read – they’re also reshaping the way we use the library, not to mention how much we spend on books.

When you think about using the library now, you may think of getting in the car, driving to the nearest branch, finding the book you’re looking for – hopefully all the copies won’t be checked out – then waiting in line to borrow it. But what if all you had to do was log on to the library’s website, do a quick search, then click “download”?

That’s now happening with thousands of books at thousands of libraries around the country. It’s a whole new world of convenience – and one that may appeal to a whole new type of library card-holder: younger, tech-savvy readers who may not have considered the library before, but now see that free e-books and instant downloads make the library a better alternative than iTunes or Amazon.

Today there are two potential drawbacks when it comes to downloading e-books free from the library as opposed to paying for them from commercial sources. The first is that library e-books don’t work on all e-readers – notably the most popular e-reader, the Amazon Kindle.

Many libraries use a company called Overdrive to supply their down-loadable audio and e-books. Here’s a look at compatible devices for Overdrive – you’ll find a lot of devices that handle audio books, but not as many that handle e-books. Another big distributor of both e-books and audio books to libraries is Netlibrary: you can see their list of compatible hardware here.

In short, you can probably listen to audio books on most anything: most Apple devices, including the iPad and iPhone 4, as well as most other smart phones. You can read e-books on the Sony Reader, Barnes & Noble’s Nook and a few other readers – and of course on any computer, either PC or Mac – but you can’t read most library e-books on the Amazon Kindle.

The second potential problem when it comes to using your local library as a sole source for e-books is that they probably aren’t carrying a complete catalog – at least not yet. The reason? As I said in the video above, some publishers aren’t playing ball with libraries because there just isn’t enough money in it for them. The publisher of my latest book, Life or Debt 2010, Simon & Schuster, has thus far has refused to do digital deals with libraries. According to this article from the New York Times, MacMillan is another publisher not providing e-books to libraries.

But according to the librarian I interviewed, these problems will ultimately be ironed out as the demand for e-books continues to expand and publishers work out a profit model that works for all parties involved.

Bottom line? The best way to save more is to find ways to do it without sacrificing your quality of life. And here we have a text-book example: you can now download many of the same e-books free from your library that you’d have to pay for at an online bookstore.

And e-books aside, don’t forget that your library is a wonderful source for virtually every kind of entertainment, from books to music to movies. As I said in the video, you’ve already used your tax dollars to buy and store all this stuff – why would you go out and pay for it? Spend a few minutes today at your local library’s website and see what you’ve been missing.

Best of America: Best Road Trip

Tyler Kellog drove more than 3,000 miles last year. His goal? Help as many people as he could.
From Reader's Digest

Tyler Kellogg calls himself a chronic do-gooder, and what he did last summer is proof: After scraping together $2,000 and retrofitting his car with a sleeping space, the 21-year-old college student hit the road. His goal: to bestow random acts of kindness on 100 strangers.


He drove 1,600 miles, from his parents’ house in Adams Center, New York, to the Florida Keys, then back again. “The first person I helped was a guy installing a boat lift on a lake in Oneida, New York,” Kellogg recalls. “I was shaking when I asked if he needed a hand.” What if he thought Kellogg was crazy? “When he said, ‘Can you help me get this lift into the water?’ I knew everything was going to be fine.”


He helped a cop fix a downed barricade in Washington, D.C., and spread countless cubic yards of mulch in Maryland and North Carolina. And somewhere outside Atlanta, he met a man who was crying because his wife had recently died and he had no one to talk to. “For three hours we sat on his porch,” Kellogg says. “When I left, he said, ‘Thank you. I realize now that my life will go on.’ ”


In 55 days, Kellogg assisted 115 strangers and made an exhilarating realization: “You don’t have
to be a billionaire to be a philanthropist,” he says. “You just have to ask people, ‘How can I help?’ ”

MIT Researchers Develop a Way to Funnel Solar Energy

MIT Researchers Develop a Way to Funnel Solar Energy

SEPTEMBER 13, 2010Massachusetts Institute of Technology

Using carbon nanotubes (hollow tubes of carbon atoms), MIT chemical engineers have found a way to concentrate solar energy 100 times more than a regular photovoltaic cell. Such nanotubes could form antennas that capture and focus light energy, potentially allowing much smaller and more powerful solar arrays."Instead of having your whole roof be a photovoltaic cell, you could have little spots that were tiny photovoltaic cells, with antennas that would drive photons into them," says Michael Strano, the Charles and Hilda Roddey Associate Professor of Chemical Engineering and leader of the research team.Strano and his students describe their new carbon nanotube antenna, or "solar funnel," in the Sept. 12 online edition of the journal Nature Materials. Lead authors of the paper are postdoctoral associate Jae-Hee Han and graduate student Geraldine Paulus.Their new antennas might also be useful for any other application that requires light to be concentrated, such as night-vision goggles or telescopes.Solar panels generate electricity by converting photons (packets of light energy) into an electric current. Strano's nanotube antenna boosts the number of photons that can be captured and transforms the light into energy that can be funneled into a solar cell.The antenna consists of a fibrous rope about 10 micrometers (millionths of a meter) long and four micrometers thick, containing about 30 million carbon nanotubes. Strano's team built, for the first time, a fiber made of two layers of nanotubes with different electrical properties — specifically, different bandgaps.In any material, electrons can exist at different energy levels. When a photon strikes the surface, it excites an electron to a higher energy level, which is specific to the material. The interaction between the energized electron and the hole it leaves behind is called an exciton, and the difference in energy levels between the hole and the electron is known as the bandgap.The inner layer of the antenna contains nanotubes with a small bandgap, and nanotubes in the outer layer have a higher bandgap. That's important because excitons like to flow from high to low energy. In this case, that means the excitons in the outer layer flow to the inner layer, where they can exist in a lower (but still excited) energy state.Therefore, when light energy strikes the material, all of the excitons flow to the center of the fiber, where they are concentrated. Strano and his team have not yet built a photovoltaic device using the antenna, but they plan to. In such a device, the antenna would concentrate photons before the photovoltaic cell converts them to an electrical current. This could be done by constructing the antenna around a core of semiconducting material.The interface between the semiconductor and the nanotubes would separate the electron from the hole, with electrons being collected at one electrode touching the inner semiconductor, and holes collected at an electrode touching the nanotubes. This system would then generate electric current. The efficiency of such a solar cell would depend on the materials used for the electrode, according to the researchers.


Strano's team is the first to construct nanotube fibers in which they can control the properties of different layers, an achievement made possible by recent advances in separating nanotubes with different properties.While the cost of carbon nanotubes was once prohibitive, it has been coming down in recent years as chemical companies build up their manufacturing capacity. "At some point in the near future, carbon nanotubes will likely be sold for pennies per pound, as polymers are sold," says Strano. "With this cost, the addition to a solar cell might be negligible compared to the fabrication and raw material cost of the cell itself, just as coatings and polymer components are small parts of the cost of a photovoltaic cell."Strano's team is now working on ways to minimize the energy lost as excitons flow through the fiber, and on ways to generate more than one exciton per photon. The nanotube bundles described in the Nature Materials paper lose about 13 percent of the energy they absorb, but the team is working on new antennas that would lose only 1 percent.

Chapmans' family tour will share pain and joy

September 19th, 2010


The family of Christian music singer Steven Curtis Chapman has been very open about the pain they have felt since the death of Maria Sue Chapman two years ago.

The 5-year-old was accidentally struck by a SUV driven by one of her brothers, in the family's driveway in May 2008. The family has shared their journey of grief with their fans through media interviews.

Steven Curtis Chapman also sang of his pain and his hope for the future in his most recent album, "Beauty Will Rise," and his wife, Mary Beth, has written a book, "Choosing to See," in which she talked about the challenges of her life, including Maria Sue's passing.


Now the family has taken the journey on the road, with a "Night with the Chapmans" tour. Steven Curtis and Mary Beth are being joined by sons Caleb and Will for the series of fall events.

The concerts in part will help the family continue healing, they said.

"We're still learning to live this new normal of life," Steven Curtis Chapman said just before the tour began last week. "There are days that we're doing really good and we feel like we are getting wind in our sails. And then days, seasons, when it just hits you again and kind of takes you back."

Mary Beth has always been behind the scenes, but she feels like this is an important part of being a steward of the story, he said.

She'll have a very informal session interacting with the audience, he said.

She's never been one to step into the spotlight of her famous husband, never been one who wanted a celebrity lifestyle. She has done some appearances on her book tour, but having her husband and sons there will make the concerts easier on everyone, Steven Curtis Chapman said.

"There's no doubt that us as a family standing on stage together saying that we're trusting in the Lord and we trust in God, that he is doing something out of this that is going to be good and healing and helpful in the lives of other people - and that's part of the healing process for us."

Caleb Chapman said that in rehearsals it was obvious that the shows were going to be emotionally charged. But the family wants to reflect on the positives of bringing Maria Sue into their lives and to show the goodness of God's promise for life in Heaven.

"We really want this to be more about the hope and the joy that we found through this suffering," he said. "We really want to encourage people."

Caleb, the front man and lead guitarist for a four-piece band called "Caleb," will open the show, the first time his group has opened for his dad. He said fans of Steven Curtis Chapman should expect a different sound than his father. He plays in a young rock band he hopes "won't be too loud," he said with a laugh.

But that's not to say that his Dad hasn't influenced him. It's more in the craft of being a musician, he said. By watching his father through the years he learned the trade and how to write songs.

"He plays a huge role in my music, whether you hear it or not," Caleb Chapman said. They are still working out whether father will join sons for a number in the opening act, Caleb said (Caleb and Will Chapman are also a part of Chapman's backing band).

Caleb will play songs from independently produced EPs, including a recently released single "We Will Wait."

The tour runs through late November. If you are going to attend you can request a song through Steven Curtis Chapman's tour page. Just make sure you request a song that he actually sang.

"Sometimes people say, 'We want to hear you sing that 'Friends' song of yours. We love that one,'" he said. "Well, that's Michael W. Smith ... but I'll sing it if you want me to."

When he does sing one of his most popular songs, "Cinderella," he says he'll take comfort in knowing somewhere Maria Sue is listening.
