This is a pretty neat concept demonstrated in the video shown below.  The device captures energy when the wind vibrates a special material at a fast frequency and then converts it into energy.

Pollution turned into renewable energy

Sandia National Laboratories have discovered how to re-energize carbon dioxide and turn it back into fuel using the sun. They have proven their theory however will it be efficient enough for governments to invest in the technology? If successful, it would take 15 to 20 years before it is used in the market.

It is very interesting how they talk about applying this technology to coal power plants which they would harvest the carbon dioxide created from the fossil fuels and turn it into a fuel, perhaps gasoline, jet fuel, methanol, or almost any type of liquid fuel. Now that is recycling!

I hope these technologies along with others get applied soon otherwise everyone will get stuck with lung cancer. China is pretty bad, their carbon dioxide reached 18.57 million tons in 1999 and the lung cancer rate is over 1 million people new cases per year.

LCD flat screen

When shopping for a new television you probably noticed the 720p, 1080i or 1080p labeled on the box. What does it all mean? The store clerk might convince you that 1080p is the best and you should get one. The television might be capable of displaying 1080p but is the source able too? Examples of sources include: Blu-ray, HD DVD, cable, satellite, gaming consoles.

Blu-ray, HD DVD and gaming consoles provide true high definition representation. Nintendo Wii displays 480p (not HD) while Xbox 360 can displays 1080i and Playstation 3 can displays 1080p.

On the other hand the satellite or cable companies keep advertising that they offer HD. Well those channels are not always 24×7 and some are only up converted to higher resolution but not necessarily HD. Why would you pay so much for only 30 channels? Yes, HD is nice but in my opinion it is too expensive to pay for.

Disadvantages of HD (Cable or Satellite)

-Regular channels are ugly since the aspect ratio makes your image look fuzzy
-Regular channels have a black bar on both sides of the image
-Not enough high definition channels
-Too expensive for the few channels that you have to pay extra for.
-Not all channels are true high definition
-Service providers compress the feed which cause images to lose quality

Advantages of HD

-Enjoy high definition gaming from Xbox 360 or Playstation 3
-Over 500,000 more pixels then SDTV at 720p resolution
-Aspect ratio of 16:9 for a widescreen image
-Crystal clear, sharp and realistic images
HDTV is by far a technology that everyone would like to own however you should investigate what the service provider have to offer in HD including prices. Paying for an HD box and the service might cost you much more then your regular digital channels but if you have the money to spend to view around 30 HD channels, go right ahead.
