Imagine for a moment that you and a friend are on a day hike in a remote area. You get disoriented, and can't find your way back to the car. After a few hours you are really lost, darkness is starting to fall, and you start to panic. You've long since run out of water, you have no food, you haven't seen anybody else all day, and you're not dressed for the cold night temperatures. Now imagine that you have an escape route. A way to tell people exactly where you are, and that you are in trouble and need help.
That is the kind of useful technology that Isaac Daniel hopes will save people's lives. Because of an incident with his 8-year old son being reported as missing, he has created a line of sneakers with a built-in GPS tracking. They allow you to push a button on the sneaker, and send a wireless alert is sent to a monitoring service. In some emergencies (such as a lost child or missing Alzheimer's patient), a parent or guardian can ask the monitoring service to activate the GPS remotely in order to find the missing person.
What's next? This shoe is meant for emergencies, but I imagine that in the near future we will have more of these types of products around for everyday use. So for example, you will be able to create a "virtual fence" area from which they can't leave without triggering an alert to you. So if you child goes outside the neighborhood when they are supposed to be at home, you get a text message. Or if they leave school grounds during school hours (possibly due to an abduction), you get instant notification. It is always better to know about a possible abduction right away, rather than waiting a few hours until the child doesn't show up on time. It could literally mean the difference between life and death.

Turn Garbage Into Clean Energy
Read the article on www.PopSci.com
It looks as though the concept of turning garbage into energy rather than dumping it into a landfill has finally come of age. These trash converters aim to use the principle of plasma gasification to turn just about any trash (including chemical weapons, metal, and concrete) into a synthesis gas, which can be used to generate electricity, and an obsidian-like glass which can be used as a building material. It takes electricity to start the reaction, but once the reaction is going, it produces excess electricity, which can then be used to power surrounding buildings or sold back to the power grid. We're going to need a lot more of these types of converters if we hope to take care of the world's energy and garbage problems.

Urban Road Race For Robotic Cars
Read the full story on CNN.com
This is the kind of technology I've been yearning for all my driving life. Sure, it is still many years off, but at least I can now have a glimmer of hope that it will be available to me in my lifetime.
Imagine getting in your car, telling it where you want to go, and then sitting back and relaxing, maybe taking a nap, or getting an early start on your day's work. You don't have to worry about getting in an accident because your car and every other car out there are driving themselves around, without the flaws of human judgment.
One potential downside? Maybe technology (coupled with ubiquitous ultra-high-speed internet) this will encourage people to commute farther to work. After all, if you can do a lot of your work, or anything else, while driving, the driving doesn't seem like so much of a waste of time.
Of course, some will say that this technology will ultimately become fairly useless, as the promise of affordable flying cars starts to look more like a reality (see companies like Moller for more info on the future of flying cars). The concept would be the same, as you tell it where you want to go and then sit back, but the challenges of navigating through roads in the sky will be much less difficult than navigating around on the ground.
But the idea of using your driving time to do something enjoyable or productive is so alluring, that we can hardly afford not to reach for it. So raise a glass to the computer chauffeurs of tomorrow. And hope he doesn't crash as often as the computers of today.

Silent Supersonic Jet?
Read the story on CNN.com
Is it finally possible to make a "quiet" supersonic jet? The folks at Lockheed Martin's fabled Skunk Works think they've designed just such an aircraft.
With advanced design and technology, they believe they have designed a plane that can cruise at about 1100 MPH, while producing only 1 percent as much noise on the ground as the recently decommissioned Concorde. All this while obtaining considerable range (4,600 miles, Chicago to Rome), and some fairly fine luxury seating.
I for one hope that they succeed. I hope that this spurs the development of affordable and quiet supersonic passenger jets. For the last 50 years, passenger planes have gone the same speed. We have not realized any gains in the speed with which we travel through the air, despite 50 years of technology evolution. It is definitely time to move around the planet faster.

Irresponsable Media
There have been many stories in the news lately, as there always are, about world events. But in recent weeks, one story has consistently made headlines more than any other.
It concerned the death of a woman named Vickie Lynn Marshall. She grew up in Texas, with several half-siblings, in a broken home. She moved in with her aunt, and failed miserably in school, never gaining more than an 8th grade education. She decided at the age of 17 to marry a 16-year old boy and then have a child. The two seperated a year after the child was born, and she started to work at Wal-Mart, and then as a waitress at Red Lobster.
She apparently didn't like working for low wages, and decided to become a stripper. But she got a "big break" in 1992 when she got in to Playboy Magazine. She married an old billionaire, who died 13 months later, leaving her a fortune. She had a daughter by some other unknown person in 2006. Later in 2006, her son, who was a recovering druggie, died at age 20 from a combination of drug-addiction medications and anti-depressants. She finally died this year at age 39, from as-yet unknown causes. Heavy drug and alcohol use are suspected as possible culprits, as having shortened her life.
By now, you may have realized that I'm speaking about Anna Nicole Smith. Just about anyone who has read the newspapers or seen the internet has seen countless stories about her death in recent weeks.
But why is the press (and through them the American People) so intent on dwelling on this particular life? Why is it that the press puts so much attention on a stripper who one could argue has done nothing constructive for the world? Many would argue that this was a miserable failure of a human being who got lucky enough to look good nude. Many would say that she never contributed anything to society, but that she in fact helped pull society downward, and destroy value more than create value.
The sad fact of the matter is that the media loves to dwell on people like Anna Nicole Smith, and get the public to dwell on it, because of the nature of lust and greed. The really great people of the world (of whom there are many), are rarely mentioned in the press. And even when they are, it is only a quick and fleeting story, printed once and then forgotten. How many Nobel Prize winners can the average American name? How many great, ordinary, every day people who sacrifice and help those around them, are mentioned on the news when they die? How many good examples are mourned by the media today, when they pass, compared to the bad examples who only destroy our society and everything around them?
Shame on the media, for systematically destroying our values, and our society.
