Plasma TVs At High Altitudes
by: Jakob Culver
An interesting factor to consider when planning your purchase of a new plasma television is altitude. Plasma TVs use millions of tiny, gas-filled chambers to create a picture. When you move to higher altitudes, the constant pressure in the chambers and the now lower ambient air pressure create a buzzing sound reminiscent of a halogen beer sign. This buzz is a combined result of the increased power consumption necessary to overcome the pressure differential, and the increase in fan use because the high power consumption heats the unit. This change in noise is really the only difference between operating a plasma television at sea level and one operating at extreme (above 6,000 ft) altitudes.
This noise increase provides a hint as to the more serious reason to avoid using a plasma television: lifespan. The life of a plasma screen is dependent on how hard it works through the course of its life. Operating these televisions at altitudes above what they were designed for puts an excess strain on their various components. Using a plasma TV above 6,000 ft. is more likely to annoy you with additional noise than anything else, but it's a bad choice in the long run.
This pressure change is why airplanes chose to use LCD screens over plasma screens on flights that offer video entertainment. LCDs use crystals instead of gas filled chambers, and are thus indifferent to altitude changes. That said, there are manufacturers who have designed plasma televisions for use at altitudes up to 9,000 ft. You'll pay for this upgraded design, so you must decide if the price difference is worth it. So, check the elevation information for your city to determine if this should concern you, because it's not always obvious. Denver is just under the 6,000 ft. window for operating a regular plasma screen. You may see a slight difference in the lifespan of the unit here when compared to an identical television located closer to sea level, but this is likely to be very small. If you're not sure what your local elevation is, or if you're close, but still below the 6,000 ft. recommended ceiling, do some firsthand research. Go to an electronics store and test out the various plasma TVs on display. Listen closely for a buzzing or humming. You may find that your local air pressure is low enough to affect the performance of a plasma unit.
So you've done your research and planning, and you're ready to buy your plasma television? Now make sure you check your local conditions and, if necessary, invest in a high altitude plasma unit.

Lift Kits - The Raised Truck Craze Gone Wild
Lift Kits - The Raised Truck Craze Gone Wild
by: Rob Gordon
There was a day when trucks were a working man?s vehicle and scratches were expected.
Shells protected valuables and tonneau covers protected tools.
Those days are over and truck enthusiasts are souping up their rides more than ever before.
With the addition of popular movies featuring fancy cars and popular television shows that glorify plasma screens and ground shaking stereo systems, the custom truck rage is here to stay.
As a sign of manhood or personal taste, many truck owners decide to lift their rides for a performance altered appearance. Lift kits http://www.autoanything.com/category.aspx?c_id=50515&se=lift_kits can actually be found online and can be installed on your truck in a do-it-yourself fashion.
Some lift systems can be somewhat difficult to...

Plasma TV for the Home Theater
Plasma TV for the Home Theater
by: Tom Ace
One of the hottest topics in home entertainment is home theater. And one of the hottest topics in home theater is plasma TV.
Plasma TV for your home theater is actually only a receiver, much like your computer monitor, and is only one component of a great home theater. Still, it's an arguable point that the plasma TV is the part of the home theater package that you'll be viewing and is therefore a very important component.
Consider the technology of the plasma TV and you'll understand why this is such a great choice for the home theater. Typically, a plasma TV is a flat screen monitor. Because of the thin design, it becomes very versatile in the home theater design. Remember the television sets of a few decades ago? They were bulky pieces of furniture and the rest of the room was often arranged around the television set. A plasma TV, by comparison, is easier to manipulate. Most models will even...
