Is technology making people too self-absorbed?

This week’s question concerns the impact technology is having on society. Technology has made it possible for people to share every aspect of their lives - both the good and the bad – with the entire world. The insatiable desire of some people to reach out and touch each other has made Web sites like Twitter, Facebook, MySpace and YouTube phenomenally successful. Now a UK-based company called Vicon is developing a small camera, called the ViconRevue, that can be worn around the neck and automatically take pictures every 30 seconds, virtually documenting every moment of your life. The pendant-size camera, which was originally designed to help Alzheimer’s patients, can store about 30,000 images on a 1GB memory card and should be in stores next year. Fans of the concept think it’s the coolest tech-toy since the camera phone, while critics call it proof-positive that society as a whole is becoming too self-absorbed. What do you think? Is technology making people too self-absorbed?

Research: Reducing Energy Consumption in Street Lighting

Experts from Rensselaer Polytechnic Institute's Lighting Research Center (LRC) estimate that about half of the approximately 13 million streetlights in the U.S. have the opportunity to reduce energy consumption by 50 percent - translating to an annual savings of 1 billion kWh, and a reduction in power plant CO2 emissions of 546,000 tons per year.

Engineers Envision Cheaper Algae Oil Production

Compared to soybeans that produce 50 gallons of oil an acre a year, some algae can average 6,000 gallons - but it's not cheap to produce. Two Kansas State University engineers are assessing systematic production methods that could lower the costs of algae oil production. They plan to grow algae in the ocean on very large, supporting platforms.
