Facilitate space debris collection

Make all spaceship and satellite equipment from material that transmit their exact location. Develop a website, perhaps only NASA can do that, which monitors their orbital fall back to earth. By giving out the exact location of their fall on earth, space enthusiasts will go collect them. If they fall in remote places, the locals can pick them up and sell them via auction on eBay. NASA will certify the authenticity of recovered items such as an astronaut's glove claimed to be Neil Amstrong's or a screwdriver belonging to Yuri Gagarin. When facing budget cuts, NASA can collect the items itself and put them for sale on eBay to raise money for its programs:)

What if we could create some kind of artificial partial solar eclipse?

This will reduce the amount of solar energy that gets to the earth.

I think I had read somewhere that some people had come up with the idea of creating large space-blankets that will orbit the earth and reflect sunlight back to the sun.

Whatever needs to be built, the main idea is this. Since we can't seem to have a way to remove green house gases from the atmosphere, we can at least try to reduce the amount of solar energy that gets to the Earth!

Any other ideas how to do so?
