Will the celestron powerseeker 70az telescope be able to see a solar eclipse?
You don't need ANY kind of telescope to see the solar eclipse. If you have a telescope, and _IF_ you have a projection eyepiece that will project the Sun's image onto the screen, then you can use it - but the problem with viewing the Sun is more in decreasing the intensity of the image rather than magnifying it.

What are the benefits of a projection screen verses an lcd or plasma ?
When putting together your home theater system a key piece that you will need to buy is the television. While there are many different technologies to choose from, you could benefit from getting a projection flat screen TV. A projection flat screen TV may not be the sleekest looking television, but it can provide you with the deepest colors of all technologies. These TVs use digital light projection technology and has the deepest contrast ability of all televisions. This allows dark colors to appear much darker and light colors to appear much lighter than other technology TVs, which gives an overall sharper picture.
What you can use for rear screen projection?
Rear projection screens are difficult to make. They have to achieve two things in order to work: First, they need to pass light freely. As the projector is behind the screen, the audience in front of it would see nothing if the screen failed to pass light from one side to another. Secondly, they have to prevent light passing straight through or no image would be seen, just the light from the projection lens. The two requirements are in conflict with each other. The more that light is captured by the screen and then dispersed, the less is actually delivered to the viewer. The more that light passes freely through the screen, the more obvious the light source becomes. Screen manufacturers spend a great deal of time and money to produce either rigid or flexible surfaces that meet both requirements and result in an evenly illuminated image. Homegrown equivalents are hard to produce but there are two ways that may produce results. In past times, glass was ground on one side to produce a frosted surface. Glass producers can still carry out the process but the cost is likely to be even higher than purpose made screens. The other option is remarkably low cost. Translucent paper such as tracing paper, baking paper, greaseproof paper etc can be used for small screens. Held flat in a frame, these papers can produce a fairly respectable image. Most certainly, they are not equivalent to a good projection screen, but for cost, they are unbeatable. Finally, stage effects sometimes use a gauze as a screen. The open weave makes them semi transparent and they can be used as a form of rear projection screen. They only work from a distance so for normal rear projection applications they won't be very effective. Treat all of the ideas as experiments and have fun with them.

How do you use your own green screen?
Well, you need to hook up the screen to the computer, and you can then add images and videos. The green pigment is an unnatural color, so you need to make sure nothing else you are filming is that shade of green. Then, use your software to select an image and the green screen shade, and then the image will appear when you use the software.
Why does your monitor have a video on it when not in use?
I assume you are talking about the screen saver. In "traditional" monitors, the large bulky ones that are CRT or Cathode Ray Tubes they were sensitive to a stationary image being displayed too long. An image left stationary would 'burn' an image into the screen and effectively ruin the monitor. Screen savers were developed so that when left with a stationary image for a certain amount of time it would put up another moving image to preserve the monitor. Newer LCD or flat screen monitors don't need this as they use an entirely different process. Newer screens no longer need Screen Savers, but are kept largely for aesthetic reasons.

How convert a HTML document to Microsoft Word which is copied by screen shot from web?
A screen shot creates an image. If you want to convert the image to text you can manipulate in MS Word, you need to scan the image with OCR (Optical Character Reader) software. If you do not want to edit the text or images you captured from the Web, you can paste the screen shot into MS Word and view it that way.
