For the real ecological-minded and crafty among us, check out Green Living at Care2.com. In addition to using recycled paper for cards, they have a recipe for making recycled paper from paper shreds. If you’ve got the time, you might try it. It involves cutting bulk mail into shreds, soaking it in warm water for two hours and then putting it in a blender. It goes on from there. Care2.com is a website for folks who “care2” make a difference in the environment as well as human rights, education, women’s rights and more.
LCD VS. PLASMA TVs
To be honest, researching the best flat-screen TV for our family started as a financial consideration. If we were going to splurge on a state-of-the art TV, cost was going to be a major issue. Interestingly enough, it turned out that there was not just a cost savings but an energy savings to consider.
The LCD and plasma TVs use two different technologies. LCD TVs, or liquid crystal diode displays, are described by the LCD-TV Buying Guide as “a matrix of thin-film transistors that supply voltage to liquid crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen.” The light that passes through this matrix enables LCD televisions to display color images.
Plasma TV images are created by thousands of pixel cells. Each pixel is made up of three fluorescent lights – red, green and blue. In a plasma TV, the tiny colored fluorescent lights, primarily made of plasma gas, illuminate to form an image, according to dtvcity.com.
Both types of TVs have their good and bad points. LCDs tend to have less glare than plasmas. They perform better in bright light. Plasmas, on the other hand, do well in a darkened home theater. They are generally better for angle viewing and good for sports. On the downside, LCDs have been known to have a ghost or trailing effect, but this is less of an issue in the newer models. Plasma TVs sometimes suffer from a burned-in image effect. In other words, if an image is left on the screen too long, which sometimes happens with video games, the image leaves its mark on the screen.
